Abstract

Purpose - This study aims to investigate the market timing strategy in different market conditions (Le, up, down, normal and in-financial-crisis situation) in the ernerging market of Pakistan over the period 1995 to 2015, Furthermore, this study tests the validity of the capital asset pricing model (CAPM) and Fama and French model.
Design/methodology/approach - This study considers monthly stock returns of 167 firms and constructs six different portfolios on the basis of different size and book to market ratio, The Treynor and Mazuy model is used to capture the market timing strategy.
Findings - The results indicate evidence of the market timing in normal market conditions, However, there is less supportive evidence of market timing in up-market, down-market and in-financial-crisis situations, This study also confirms the validity of the capital asset pricing model and Fama and French three-factor model with strong support of value premium and size premium in the stock market.
Practical implications - The findings of this study are helpful to companies in estimating the cost of issuing equity more accurately, The investors can use market timing to make their investment in a more better and profitable manner.
Originality/value - Unlike other previous studies, this study considers an extended period to test the validity of the capital asset pricing model and Fama and French modeL In addition, this study is novel in testing the marketing timing of the firms in the context of emerging economy of Pakistan.

1. Introduction

Bernoulli (1954) suggests that to determine the value of an asset, we should assess the utility rather than focus only on the price of the asset. The theory of modem finance is based upon three assumptions: first, the markets are efficient; second, the investors always try to exploit arbitrage opportunity, i.e. to buy an asset at lower price and selling it at a high price to gain the profit; and third, investors are always rational. Various asset pricing models are proposed to describe the relationship between expected returns and risk. Most of the models are developed on the basis of systematic and unsystematic risk.

Markowitz (1952) laid foundation of asset pricing model. He presented the concept of tradeoff of risk and return and proposed optima! portfolios. Tobin (1958) developed the "Separation Theorem" to simplify the portfolio selection. According to the theorem, investors' need to identify risky assets and then decide his borrowing or lending preferences. In this manner, investors' will hold one portfolio, which would also be a market portfolio. Sharpe (1964) introduced a much simple version of portfolio analysis models, and provided method of asset pricing, to price the portfolios by simply taking the weighted average of the returns which is known as capital asset pricing model (CAFM).

CAPM can be helpful to quantitatively find out the association among the beta of the asset, its expected associated retum, while beta is the measure of sensitivity for the non­diversifiable risk of the asset. For portfolio investment, beta is an important factor for making the investment decision as well as to estimate the expected returns. Moreover, according to the CAFM, the relationship between the risk and return is always linear in nature, but Fama and French (1992) proved that relationship between risk and retum is quadratic and not linear. Hence, there are other risk factors that explain the retums of assets, except those that are explained by the market beta.

On the other hand, there are two more variables that are included by the Fama and French (1992) in the original CAPM to observe the selectivity and value premium and size premium, which is the micro-forecasting ability of the managers. As CAPM is a single factor model, and inc1udes only the market risk, Fama and French proposed a three-factor model. In their model, they inc1uded two more variables: size variable, or the size premium, and BV/MV ratio, or the value premium, along with the original market risk. They proposed that two types of stocks performed well than the other stocks. They are either growth stock, which has low BVIMV ratio, or value stocks which has high BV/MV ratio of the stocks. They argued that companies with low BV/MV ratio indicate the higher eamings and performance, while companies or stocks with low BV/MV indicate the distress position of the company. Moreover, small-sized companies or companies with small market capitalization show low earnings, but returns on such companies' stocks compensate the low earnings. Hence, investments in small-sized firms and high-BV/MV ratio firms are compensated with higher returns.

Treynor and Mazuy (1966) introduced the market timing model to observe if investors time the market while making investment decisions. Market timing, in simple words, is a strategy to decide the right time to invest in a particular stock or fund. It can be done by predicting if the market will be bullish or bearish, which is basically forecasting the future trend of the stock market (Olbrys, 2010). A portfolio is shaped in such a manner that it moves according to the price changes and the market as a whole. Portfolios are structured according to these expectations. The purpose of this strategy is to outperform or beat the market as investor tries to forecast the market trends in near future. This strategy is used to structure the portfolio for the mutual funds mostly, hence mostly used by the mutual funds manager (Skrinjaric, 2013). According to Prigent (2007), market timing is a strategy that is linked with the beta, if the beta is less than one than the stock market is bearish and if it is greater than 1, than the stock market is bullish. Research on funds is done initially by the Treynor and Mazuy (1966) and Henriksson and Merton (1981). Most of the later research on the market timing has been done by using the two market timing models mentioned in the study.

This study is an attempt to investigate the validity of CAFM, Fama and French three­ factor model and the presence of market timing in the emerging stock market of Pakistan. In reference to Pakistan, only few studies have been carried out[1], in which most of the studies investigate mutual funds and considered small sample periodo In contrast, this study focused on individual stocks with a sample of 167 companies. In addition, this study considers an extended period of 20 years (1995-2015) for analyses, which will provide more robust results. To the best of the authors' knowledge, this study is the first to investigate the market timing in the stock market of Pakistan, considering different market conditions. In particular, this study adds to the literature in four aspects. First, this study will provide information about the market timing in Pakistan Stock Exchange (PSE). Second, this study will provide information about market timings in different market conditions, i.e. up-market (bullish), down-market (bearish) and normal conditions. In addition, this study will examine the market timing during the financial crisis period[2]. Third, this study will test the validity of CAPM. Fourth, this study will test the validity of the Fama and French three-factor model. More specifically, this study will explore the effect of value and size premiums on the stock market. This study will provide valuable information to investors, fund managers, policymakers and companies.

The rest of the study is organized as follows. The Section 2 reviews the models. Then Section 3 presents the methodology. Section 4 presents the results, and Section 5 conc1udes.

2. Review of literature and models

2.1 Market timing

Treynor and Mazuy (1966) are the pioneers in conducting the research on the market timing ability of funds. They studied 57 American funds and concluded that only one of the funds was following market timing ability. Several studies conducted on market timing ability of funds have confirmed the original findings (Cumby and Glen, 1990; Gjerde and Szettem, 1991; Liljeblom and Loflund, 2000).

However, Treynor and Mazuy (1966) market timing model received several criticisms. Ippolito (1993) criticized Treynor and Mazuy for using insufficient observations of each fund and for studying the market timing model of individual funds. Ferson and Schadt (1996) suggested that investors increased their investment when they predicted higher returns in future and that it could be the reason for the funds to have low market exposure during the period when the expected retums in the market were high. Henriksson and Merton (1981) used a new approach in market timing model and included a dummy variable to assess the macro-forecasting ability of the fund's manager. However, they observed similar results such as Treynor and Mazuy research.

Several studies have been conducted on investigating the market timing model, among which a few of the studies reported the absence of the market timing model (Bollen and Busse, 2001; Cumby and Glen, 1990; Eun et al., 1991; Henriksson, 1984; Kao et al., 1998; Liljeblom and Loflund, 2000; Romacho and Cortez, 2006). Apart from the aforementioned studies, sorne of the studies reported the presence of positive market timing ability in the funds (Black et al., 1992; Gjerde and Saittem, 1991; Sandvall, 2001; Yu et al., 2010). On the contrary side, few of the studies reported negative market timing abilities (Ferson and Schadt, 1996; Leger, 1997; Yu et al., 2010).

The literature also provides evidence of market timing abilities of managers in emerging markets. For example, Unal and Tan (2015) studied the Polish fund managers over the period January 2009 to November 2014, considering the post-financial-crisis period of 2008. They suggested that Polish fund managers had no ability to time the market during the quantitative easing era. Similarly, Aiken et al. (2016) found no evidence of overall market timing ability in emerging market using pooled and calendar-time approaches. However, they found sorne evidence of market timing in the financial crisis period and during the subsequent recovery periodo In contrast, Liao et al. (2017) documented that Chinese mutual fund managers have the ability to time market returns, liquidity and volatility. Similarly Yi et al. (2017) found strong evidence that Chinese mutual funds can time the market liquidity and volatility. They further suggested that only growth mutual funds have the ability to time the market retums. The aforementioned discussion shows that there is inconsistent evidence regarding the market timing ability of the managers in emerging markets. Therefore, studying the market timing ability of managers in the context of Pakistan will add sorne valuable knowledge to the existing literature regarding emerging markets.

2.2 Fama and French

Fama and French (1992) added two more factors into the original CAPM to measure the company specific risk factors. They separated the firms on the basis of size of the company and the BV/MV ratio of the company. They argued that companies with high BV/MV ratio are valued firms, which provide more retums to compensate for the level of extra risk associated to those, while companies with low BV/MV ratio are the growth firms, and these companies provide less returns as compared to the value firms. Moreover, small-sized companies tend to have small market capitalization, and to compensate the extra risk associated with small-size firms, the returns provided by such firms are greater than the firms with high market capitalization.

Fama and French (1992) added value and size premiums as additional variables to the original CAPM model. They studied stock of three American markets: NASDAQ, NYSE and AMEX. They sorted the stocks by their size, i.e. the equity market value for the selected markets and ten portfolios were constructed on the basis of size. By applying the Fama and MacBeth approach, they found that beta was not enough to explain return variations; the size and value premium ratio was also explaining changes in the returns. In the subsequent paper (Fama and French, 1993), confirmed similar results by considering stocks and bonds, which confirmed the reliability of the three factor model.

Several studies have been carried out to study the three-factor model and CAPM. Most of the studies reported supportive arguments in favor of the three-factor model, that the three­ factormodel is better in explainingreturns than CAPM (Abbas et al., 2014; Aleati et al., 2000; Claessens et al., 1995; Drew, 2003; Drew and Veeraraghavan, 2002; Hassan and javed, 2011; Mirza and Shahid, 2008). However, Qi (2004) conc1uded that CAPM is still a better measure to explain stock returns.

2.3 Up-market and down-market

The single factor CAPM model was not able to describe the returns of the stocks, and it was criticized because of up-market and the down-market conditions in the stock market. Pettengill et al. (1995) mentioned that beta has a tendency to behave altogether different in the up-market as well as down-market conditions. According to them, bullish market, or the up-market, is when the returns from the market are positive and beta is positive and it results in normal relationship of risk and return. In case of down-market, or bearish market, however, the beta is negative; hence, there is a negative relationship between the risk and the retum. They ascertained it through their study and provided sufficient amount of evidence showing inability of the beta to describe the returns in the market as described by Fama and French in their different researches.

Fletcher (2000) used the international markets returns of 18 international markets' stocks to show the conditional behavior of the beta for the period between 1970 and 1998. Their results showed consistency with Pettengill et al. (1995) that beta did change the relationship as well as the significance of the relationship with returns. Woodward and Anderson (2009) also verified the conditionality of beta and concluded that investors' tend to move through the different markets, which indicates the consistent beliefs. Zhang and Wihlborg (2010) collectively analyzed the six international markets by using the data of more than one thousand companies from 1996 to 2006. They reported consistent findings such as Pettengill et al. (1995) that performance of the beta varies in the up market and in the down market.

3. Methodology

3.1 Sample selection

The sample consists of monthly stock returns from the Pakistan Stock Exchange over the period from February 1995 to May 2015. The main aim of using monthly retums for such a longer period is to get more accurate results[3]. The final sample includes 167 firms, considering availability of the data[4]. We used Pakistan's Treasury Bill yield, with six months maturity as a proxy for the risk-free rate of return. In particular, there is no risk-free asset available in the market, and that's why government securities are treated as risk-free assets. However, even though government securities are considered to be risk-free, they are not entirely without risk; for example, inflation risk is always attached to such securities.

3.2 Treynor and Mazuy market timing model

Treynor and Mazuy introduced the market timing model, which was based on regression analysis. The proposed model is built on the quadratic term to find out the realized portfolio returns. The model is given as follows:

rp,t = αp + βp . rM,t + γp . (rM,t)2 + εp,t             (1)

In equation (1), rp,t = Rp,t - RF,t is the simple excess return on portfolio P in period t, rM,t = RM,t - RF,t is the simple excess return on portfolio M in period t, Rp,t is the one-period retum on portfolio P, RM,t is the one-period return on market portfolio M, RF,t is the one-period return on riskless securities, βp is the systematic risk measure of portfolio P, γp measures the market-timing ski lis of the manager of portfolio P, αp measures the selectivity skills of the manager of portfolio P and εp,t is a residual term, with the following standard CAPM conditions E εp,t = 0, E (εp,t εp,t-1) = 0.

Furthermore, if the manager of the portfolio forecasts the stock prices successfully, the αp will be positive, and vice versa. If the manager successfully times the market, then the γp will be positive, showing the existence of the market timing.

3.3 Modified three factor model afier the incorboration of market timing

Fama and French introduced the multifactor model for size and value premiums along with the market premium from the original CAPM, which is given as follows:

rp,t = αp + βp . rM,t + δ1p . rSMB,t + δ2p . rHML,t + εp,t             (2)

In equation (2), rSMB,t = RSMB,t - RF,t is the simple excess return on the mimicking portfolio 5MB in the period t, rHML,t = RHML,t - RF,t is the simple excess retum on the mimicking portfolio HML in the period t, δ1p is the measure of the sensitivity of the returns on portfolio P to changes in the 5MB factor returns and δ2p is the measure for the sensitivity of the returns on portfolio P in response to the changes in the HML factor returns.

However, this model still does not incorporate the market timing premium. Hence, Olbrys (2010) introduced a modified Henriksson and Mazuy model for their research and inc1uded market timing variable into the original Fama and French three-factor model by inc1uding the square of rM,t. We monitor the fol1owing model in this study:

rp,t = αp + βp . rM,t + δ1p . rSMB,t + δ2p . rHML,t + γp . (rM,t)2 εp,t             (3)

From equation (3), rp,b rM,t, αp, βp, γp and εp,t are explained in equation (1) and δ1p, δ2p, rSMB,t and rHML,t are explained in equation (2).

3.4 Market timing model under conditional markets

We created dummy variables for the up-market and down-market conditions and for the financial crisis period, and inc1uded in the Treynor and Mazuy market timing model.

3.4.1 Up-market condition. For the up-market condition, a dummy variable rUM,t for the up-market was created, which was then inc1uded into the Treynor and Mazuy market timing model. The model is given below:

rp,t = αp + βp . rM,t + γp . (rM,t)2 + βU . rUM,t + εp,t             (4)

From equation (4), rp,t, rM,t, αp, βp and εp,t are explained in equation (1), βU measures the market-timing skills of the manager of portfolio in up market, and rUM,t = (rM,t)2*UM, where UM is the proxy variable for the up market.

3.4.2 Down-market condition. For the down-market condition, a dummy variable rDM,t for the down market is created, which is then included into the Treynor and Mazuy market timing model. The model is given below:

rp,t = αp + βp . rM,t + γp . (rM,t)2 + βD . rDM,t + εp,t             (5)

In equation (1), βD measure the market-timing skil1s of the manager of portfolio in down market,

rDM,t = (rM,t)2*DM, where DM is the proxy variable for the up market.

3.4.3 Financial crisis. For the down-market condition, a dummy variable rrc¡ for the down-market is created, which is then inc1uded into the Treynor and Mazuy market timing model. The model is given below:

rp,t = αp + βp . rM,t + γp . (rM,t)2 + βFC . rFC,t + εp,t             (6)

In equation (6), f3 FC measures the market-timing skil1s of the manager of portfolio during financial crisis and rFC,t = (rM,t)2*FC, where FC is the proxy variable for the financial crisis.

3.5 5ize and BV/MV portfolios

Size portfolios are based on the market capitalization of the stocks. To make the size portfolios, stocks from the Pakistan Stock Market are initially arranged according to their market capitalization, in which market capitalization represents the size of the firmo We then ca1culated the median size of the sample and divided into two equal parts. Stocks above the median represent the big size (B) firms, while those below the median represent small size (S) firms. We define the size of the firms according to the aforementioned method.

Initially book value is divided by the market value of the stock to calculate the BV/MV ratio. After calculating the book value to the market value ratio for the stocks, all stocks are arranged in descending order according to their BV IMV ratio. After arranging the stocks in order, they are divided into three parts; bottom 30 per cent, middle 40 per cent and top 30 per cent. These stocks are c1assified according to their rank, as top 30 per cent stocks are categorized as high (H), middle 40 per cent stocks are categorized as medium (M), while bottom 30 per cent is categorized as low (L). By doing this, stocks are divided into high (H), medium (M) and low book (L) value to market value ratio.

After getting the two portfolios on the basis of their size and three portfolios on the basis of the BV IMV ratio, intersection of both types of portfolios is done. Following the aforementioned procedure, we constructed six different type of portfolios based upon different size and BV/MV ratio. These six portfolios are B/H, B/M, B/L, S/H, S/M and S/L. The B/H stocks are stocks that have big size and high BV/MV ratio. B/M stocks are stocks that have big size and medium BV IMV ratio. BIS stocks are stocks that have big size and low BV/MV ratio. S/H stocks are stocks that have small size and high BV/MV ratio. S/M stocks are stocks that have small size and medium BV/MV ratio. S/L stocks are stocks that have small size and low market ratio.

Table I provides the summary of the number of firms in each portfolio over the years. We used monthly data from Feb 1995 to May 2015. The number of firms' average is taken for the year and that average is used as yearly mean number of firms in each portfolios.

 

According to Table 1, on average, there are 5 firms through the period of the study in S/L while there are 16, 19, 24, 25 and 9 firms are in the S/M, SIR, B/L, B/M and B/H, respectively.

Once portfolios are developed, next step is to find out HML and 5MB.

5MB is the risk premium for the retums related to the size of the firm. It is calculated by taking the difference among the retums of the equally weighted three small size firms' portfolios and three big size firms' portfolios. It is ca1culated by using the formula given below:

 

HML is the portfolio's value premium. It is the difference between the high, medium and low BV/MV ratio stocks' portfolio retums.

 

Portfolio retums are taken at t + 1 period, as taking returns at time t is conceptually wrong because one cannot eam the retum at the time investment is made, hence retums are generated after at least one period of the investment.

4. Empirical results

4.1 Descnpiioe statistics

Table II presents the summary statistics of the variables. The results show that mean retums increases from the low to high BVIMV ratio as the BV/MV ratio increases with increase in average returns. On the other hand, except for the portfolio SL and BL, small­sized portfolios have high average retums as compared to the large size, which confirms the negative relationship between the size and retum. Average retums for the six portfolios ranges between 0.0106 to the 0.0403. The standard deviation of the portfolios is also very low, as for all of the portfolios standard deviation is under 0.1 except for the SL and BH portfolios. Furthermore, the range of the retums is wider for the small-sized portfolios and narrow for the big-sized portfolios. None of the portfolio has foHowed the normal distributed returns. As it can be seen in the table, SL, BL and BM are negatively skewed with kurtosis more than three, while the remaining three portfolios, SM, SH and BH, are positively skewed, and their kurtosis ranges from 4.096 to the 6.896.

 

Table II shows the descriptive statistics for the explanatory variables. Average retums for the 5MB factor is 0.00468, for the HML factor 0.0211, for the market retum 0.0120 and for the market timing it is 0.00820. The standard deviation for all of the four types of variables is below 0.1. The range for the retums is lowest for the 5MB factor, and market retum is highest for the market timing. Furthermore, none of the variables has foHowed the normal distribution, as 5MB and market retum factor has negatively skewed distribution with kurtosis more than three. On the other hand HML and market timing factors has positively skewed retums with kurtosis more than three too.

4.2 Correlation matrix

Table III represents the result of the correlation among six portfolios. The results show that SL portfolio has low correlation with the other five portfolios. On the other hand, rest of the portfolios has very strong correlation with each other. The minimum correlation lies between the SIL and the BIH, while highest degree of the correlation is between the BIL and the BIM. AH these results suggest that if an investor wants to diversify the risks by investing in more than one portfolio, he/she should make a combination of portfolios with the SIL portfolio, as only SIL has the minimum degree of correlation with others.

 

The market risk return, 5MB and HML have positive but weak correlation. The correlation between 5MB and market risk premium is negative and more than 0.5, which is a slightly strong correlation. The market risk premium and HML are also positively correlated. However, the correlation between 5MB and HML is negative (-0.413).

4.3 Fama and French three-factor model with size and value premiums

Table IV shows the results of traditional Fama and French three-factor model. The impact of market, size and value premiums is tested on portfolio returns from the PSE. The results suggest that market premium for the systematic risk (βp) is significant. In case of SMB factor or the size premium, (δ1p) three out of the six portfolios are significantly positive, which suggests that investors do consider the size of the firm and its market capitalization while investing. It affirms the literature that small firms or portfolios offer more retums as compared to the big size firms or portfolios to compensate the investors for the extra risk, which they took for investing in small-sized firms or portfolios. The results of the HML factor or value premium (δ2p) shows that value premium for four out of six portfolios indicated significant positive signs, while only two portfolios with low BV/MV ratio have negative coefficients, which indicates that few of the investors invest in high value firms or portfolios.

 

4.4 Modified Fama and French ihree-factor model with market timing

Table V presents the results of modified Fama and French's three-factor model. It shows that systematic risk (βp) is significant for all portfolios. The results of the 5MB factor or size premium (δ1p) of three portfolios (with small capitalization) have significant positive coefficient, which suggests that small-sized firms offer more retums as compared to big­sized firms to compensate for the higher levels of risks associated with those. The HML factor or the value premium (δ2p) is significant for all portfolios having positive coefficient in four out of six portfolios. The low BV/MV ratio portfolios has negative coefficients, which confirms that they are growth portfolios, and they give low retums as compared to the other four portfolios which have medium or high BV/MV ratio. The results of this study show that market timing (γp) is used by the investors in PSE. The results suggest the positive market timing ability of the investors, which means investors in PSE do anticipate the market trends in advance and get benefit out of the bullish market and minimize the deficits of bearish trend of the market.

 

4.5 Treynor and Mazuy market timing model

The impact of market timing by using the Treynor and Mazuy model is presented in Table VI. The market risk is significant for all of the portfolios. The value of the beta is also less than 1, which is owing to the inc1usion of the market timing variable into the model. Furthermore, the impact of market timing is significant in five out of the six portfolios; hence, it can be concluded that market timing influence the PSE. The coefficient of the market timing is positive for all six portfolios. The intercept or the alpha, which also measure the selectivity, is significant for the three portfolios. So, it can be concluded that not all investors practice the selectivity while making investment in the PSE stock portfolios.

 

4.6 Capital asset pricing model

Table VII shows the results of traditional CAPM model. The results suggest that all six portfolios have significant coefficient ranging from 0.30 to 1.09 with standard errors less than 1. If we compare it with the modified three-factor model, the coefficients of original CAPM model are lower than the three-factor model and the range of the standard errors for the market risk is also greater than the three-factor model.

 

If we compare the R2, results are quite different, as in case of one portfolio (SL), the value is only 0.074, while the highest value for any portfolio is 0.75. In case of the three-factor model, value of the R2 ranges from 0.57 to 0.85. Hence, we can state that on the basis of R2, the three-factor model explains the variation in the portfolio retum more than the single factor CAPM model. Furthermore, the value of βp increased by adding the HML and 5MB factors, which affirms the results of Fama and French (1993).

4.7 Modified Treynor and Mazuy model with an up-market variable

The impact of market timing in the up-market condition is shown in Table VIII. The results show that systematic risk is significant in all of the portfolios. The notable finding suggests that market timing coefficient is significant and negative in all portfolios. The possible explanation of the negative coefficients will be that investors or managers are not able to time the market correctly in up market conditions. These results are inconsistent with the literature because most of the studies reported positive market timing coefficient. Olbrys (2010) studied the up- and down-market conditions, with one period lag variable for the conditional market timing. Hence, the same methodology is repeated in this study to see whether the theoretically achievable results could be achieved. Hence, the Treynor and Mazuy model is tested again for the up-market condition with a lagged dummy variable.

 

A dummy variable of market timing in an up-market condition was created, and one lag was inc1uded into the Treynor and Mazuy model to further justify the impact of the market timing in up market condition, as it was originally used by Olbrys (2010). The results are shown in the Table IX, which suggests that systematic risk is significant in all portfolios, while market timing in normal market conditions is significant in five out of six portfolios. However, the results of the market timing in the up-market condition with one lag are insignificant except one portfolio. Other than in small-sized firms, with high BV/MV ratio portfolio, all other portfolios have insignificant results. Furthermore, S/H portfolio coefficient for the up market condition is also greater than 1, which confirms eaming super profit in up market conditions.

 

4.8 Modified Treynor and Mazuy model; with a down-market variable

Table X reports the results of the impact of market timing in the down -market conditions. It shows that systematic risk is significant in all of the portfolios. The notable findings suggest that the market timing coefficient is significant positive in four out of six portfolios in down­market conditions. This result shows positive market timing behavior in the down market confirming that managers cannot time the market in down-market conditions. This finding is inconsistent with the existing literature because negative market timing behavior is observed in the down-market conditions.

 

To deal with this, we foHowed Olbrys (2010) and created one-Iag market timing in down­ market condition too to see the impact of market timing in the down-market. The results are reported in the Table XI. Results suggest that systematic risk is significant for all of the portfolios in down market condition. The market timing in normal market conditions is significant in five out of the six portfolios. The results of the market timing in down market condition with one lag are insignificant except the one portfolio (BIL). Except in big-sized firms, with low BV/MV ratio portfolio, all other portfolios have insignificant results. The coefficient of the one-Iag market timing in down-market is negative, which affirm the impact of market timing in the down-market.

 

4.9 Modified Treynor and Mazuy model for financial crisis

Table XII shows the results for use of market timing during the financial distress period. The results show that market premium is significant for all of the six portfolios. The market timing is also significant for five out of the six portfolios.

 

To check the use of market timing during the financial crisis a dummy variable was created to see the impact of financial crisis. The results show that only one portfolio, i.e. B/M, has a significant negative coefficient during the financial crisis periodo Furthermore, intercept is also significant only for three out of six portfolios; it means that selectivity is not practiced by all of the investors.

5. Conclusion

The purpose of this study was to test the market timing in the emerging market of Pakistan. This study tested the market timing in up-market (bullish) and down-market (bearish) conditions. In addition, this study tested the market timing in financial crisis period of 2007. This study foHowed the Fama and French methodology and created six Fama and French portfolios by considering data of 167 firms listed on the PSE from February 1995 to May 2015. This study also tested the validity of CAPM and Fama and French three-factor model.

The results highlighted the validity of CAPM and Fama and French three-factor model. It was evident that size and value premiums impacted portfolio's excess retums. The results also highlighted the presence of selectivity in portfolios. The results indicated the presence of market timing in the portfolios in normal market condition. However the results were not strong enough to justify the presence of market timings in up-market down-market and in­ financial-crisis situations.

This study provides guidelines for investors, companies and regulators. Investors may benefit by timing their investments to maximize their retums. This study can be a guiding path for corporations to raise timely capital. Regulators can draft rules and regulations given the market dynamics and structure.

Notes

1. See, for example, Mirza and Shahid (2008); Hassan and Javed (2011); Javid and Ahmed (2008); Hamid et al. (2012); and Abbas et al. (2014).

2. There is no empirical evidence regarding market timing during the financial crisis period in reference to Pakistan. So this is the novel contribution to the literature.

3. The market timing becomes more prominent as the frequency of the data increases, and hence, it is another reason for selecting a longer range of data.

4. We excluded firms with missing observations. Furthermore, we considered all those firms for which the data was available for the selected period.
