Policies and Sustainable Economic Development | 565 Does Stock Price Reflect Earnings Persistence? Evidence from Vietnam VO XUAN VINH University of Economics HCMC - vinhvx@ueh.edu.vn CHU THI KIM HUONG Maybank Kimeng Securities Limited Liability Company HCMC - huong.chu@maybank-kimeng.com.vn Abstract This paper investigates the persistence of earnings and the contribution of accruals and cash flows component in earnings We also examine whether earnings, accruals, and cash flows are correctly priced Our data sample includes 245 listed firms on the Ho Chi Minh City stock exchange covering the period 2007 - 2013 The empirical results show that the earnings persistence rate of Vietnamese firms is quite high Moreover, we find that the accruals component of earnings causes earnings to be less persistent than the cash flows component of earnings Further, this study reports that persistence of earnings, cash flows and accruals component are not fully reflected in stock price Keywords: earnings persistence; abnormal return; cash flow; accruals; Vietnam stock market TIEU LUAN MOI download : skknchat@gmail.com 566 | Policies and Sustainable Economic Development Introduction Earnings quality is an important topic in corporate finance which draws attention from different stakeholders, including firm management and equity investors Particularly, the reliability of accounting information is clearly relevant in equity pricing This is reflected by a huge volume of papers in the literature devoted to investigate earnings quality Moreover, a large volume of papers examining earnings management (Dou et al 2016 forthcoming; Kadan & Yang 2016) The topic is important because earnings manipulation is detrimental in corporate world However, most of the papers seem to cover the data from mature markets while papers considering emerging markets tend to be limited in the literature This paper sheds further light on this important issue in the context of Vietnam, a member of CIVETS emerging markets group, which is characterized by high economic growth rate and innovative population While earnings persistence, its components (cash flow and accruals) and its role in securities pricing has been widely covered in the developed markets, study of this topic in the context of developing markets like Vietnam is relatively underexplored The central objectives of this paper are: (i) investigating the persistence of earnings and information contained in the accrual and cash flow components of earnings; and (ii) examining the magnitude to which this information is reflected in Vietnam stock market We focus on the quality of earnings using the dataset of Vietnam listed firms since the accounting fraud and earnings manipulation have recently been a serious problem More importantly, this accounting manipulation practice has been discovered in many large Vietnamese corporation Consequently, the quality of reported earnings has attracted attention from different market participants This is an important motivation for the current paper because quality of earning is more important in emerging markets due to the overall lacking of institutional quality Many previous authors also recognize the profound importance of earnings quality in emerging markets (Shen & Chih, 2007) Another important motivation of our paper is the mixed findings in the current literature Particularly, a large number of prior studies show that earnings persistence is more contributable by cash flow component than accruals component of earnings, but they also report that market participants usually overestimate more on accruals than earnings in actual investment More importantly, Sloan (1996) claims that investors concentrate on current earnings to predict future earnings in an influential work However, investors tend to fail to estimate the information contained in the two components of earnings which are accruals and cash flows Many subsequent authors extend the work of Sloan (1996) to provide further evidence on the persistence of earnings (Amir et al., 2015; Beneish & Vargus, 2002; Fairfield et al., 2003; Hanlon, 2005; Hui et al., 2016; Richardson, 2005; Subramanyam & Wild, 1996; Xie, 2001) TIEU LUAN MOI download : skknchat@gmail.com Policies and Sustainable Economic Development | 567 Our paper is also motivated by the light volume of this topic in the context of emerging markets We recognize that there is a few papers investigating earnings quality in the context of developing countries, for example, China (Navissi et al., 2006) and Korea (Hong-Bok & Gee-Jung, 2010) These papers also examine the pricing of earnings and earnings components offering consistent findings with the ones using the developed country data However, studies using the less developed country data seem to provide compelling results (Çelik et al., 2013; Clinch et al., 2012; Ozkan & Kayali, 2015) The results of this paper show that firms in Vietnamese stock market has a high level of earnings persistence Moreover, we observe that the accrual component of earnings causes earnings to be less persistent than the cash flow component of earnings These findings are consistent with previous results in the context of developed countries such as the US (Sloan, 1996) and the UK (Soares & Stark, 2009) The current paper also suggests that Vietnamese investors generally underestimate the persistence of current earnings into future earnings while overestimate the contribution of accrual component in relative with cash flow component Vietnam stock market reaction on earning persistence is inconsistent with the findings of papers using the context of developed markets, however, it is similar to the results of previous papers employing data of emerging markets, including China (Navissi et al., 2006), Korea (Hong-Bok & Gee-Jung, 2010), and Turkey (Çelik et al., 2013) The remainder of the paper is structured as follows Section reviews the literature Section introduces data and methodology Section reports the results and discussion of results Section concludes the paper Literature review Dechow (1994) demonstrates that cash flows and accruals are measures of earnings persistence and is based on the ground that the cash flows and accrual components of earnings should have similar forecasting information However, Sloan (1996) argues that accruals may be less informative than cash flows because they are less reliable To support this argument, Sloan (1996) provides evidence that accruals are less useful than cash flows in forecasting future earnings This argument indicates that earnings persistence which is contributed by the accruals component of earnings is lower persistent than earnings performance contributed by the cash flows component of earnings In the same vein, Pincus et al (2007) and Ball et al (2016) conduct the test and yield the similar findings Other studies in the context of emerging markets provide agreeable results, for instance, Navissi et al (2006) find that cash flow components of earnings mainly drive a high level of earning persistence in China, and Hong-Bok and Gee-Jung (2010) extract the same evidence for Korean stock market These findings lead to form our first testable hypothesis: H1: The persistence of earnings is lower by the contribution of the accruals component of earnings and higher by the contribution of cash flows component of earnings These pioneer works of Dechow (1994) and Sloan (1996) map the way for a voluminous papers investigating the pricing of the earnings, cash flows and accruals components of earnings (Beneish TIEU LUAN MOI download : skknchat@gmail.com 568 | Policies and Sustainable Economic Development & Vargus, 2002; Dechow et al., 2006; Fairfield et al., 2003; Fairfield et al., 2003; Hanlon, 2005; Persakis & Iatridis, 2015; Richardson, 2005; Subramanyam & Wild, 1996; Xie, 2001) However, the results are mixed While many papers demonstrate that market participants overprice the earnings’ persistence and they also overvalue the accruals components of earnings, Dechow et al (2006), in contrast, shows that market participants correctly anticipate the persistence of earnings and cash flows components of earnings The tests in the developing economies present compelling results Çelik et al (2013) and Clinch et al (2012) offer evidence from Turkey and Australia showing that market participants seem overestimate the properties of earnings persistence while fully reflect implication of accruals but underprice the value of cash flows component However, Ozkan and Kayali (2015) reports that investors react similarly on cash flows component, but different from accruals They overprice accruals in analyzing for investment From aforementioned evidences both in developed and developing markets, we predict that Vietnam investors fail to take into account the different levels of persistence of the two earnings’ components and form our second testable hypothesis as follows: H2: Stock prices fail to anticipate the higher earnings persistence contributed by the cash flows component of earnings and the lower earnings persistence contributed by the accruals component of earnings Data, variable measurement, and methodology 3.1 Data Accounting data and stock market trading data are obtained from Bloomberg database Our sample covers 245 listed firms on the Ho Chi Minh City stock exchange which have available data for the period from 2007 to 2013 We exclude banking, financial, and insurance institutions from our analysis because the distinction between operating and investing activities is not clear for these firms We also eliminate firm-year observations with insufficient data 3.2 Variable definition The financial variables used in this paper are earnings, cash flows, accruals and abnormal stock return We use the firm’s net income to proxy for earnings (NI) Sloan (1996) defines accruals as the difference between net income and cash flows from operating activities However, this definition of accruals omits cash flows from investment According to Richardson et al (2001), there is no clear evidence to expect that accruals relating to investment cash flow will be more or less reliable than accruals relating to operation cash flows To eliminate that shortcoming, we obtain accruals (ACC) definition as the difference between earnings (NI) and cash flows (CF), in which cash flows (CF) variable is measured as the sum of cash from operation (CFO) and cash from investment (CFI) Similar to Sloan (1996), in order to analyze earnings persistence and its components across a large set of firms, we standardize all of variables by scaling earnings, accruals, and cash flows by average TIEU LUAN MOI download : skknchat@gmail.com Policies and Sustainable Economic Development | 569 total assets, measured as the average of the beginning and ending year total assets These variables are defined as follows: Average total assets ( ATA) = (Total assetsbegin + Total assetsend )/2 Earnings (NI) = Cash flows (CF) = Net income (NI) Average total assets ( ATA) Cash from Operation (CFO) + Cash from Investment (CFI) Average total assets ( ATA) Accruals (ACC) = Net income (NI) − Cash flow (CF) Average total assets ( ATA) Following Alzahrani and Skerratt (2010), we use the market adjusted model to estimate abnormal returns as the difference between return of the stock 𝑹𝒊𝒕 and return of the corresponding national index 𝑹𝒎𝒕: AR it = R it − R mt The daily stock return for each stock and for the market index are calculated as follows: R it = Pit −Pit−1 Pit−1 and R mt = MPt −MPt−1 MPt−1 where: 𝐀𝐑 𝐢𝐭 is the abnormal stock return for firm i in year t; 𝑹it is the stock return for firm i in year t; 𝑷i𝒕 is the stock price of firm i at year t; 𝑷i𝒕-1 is the stock price of firm i at year t-1; 𝑹𝒎𝒕 is the return of the VN-index in year t; MPt is the VN-index value at year t; and MPt-1 is the VN-index value at year t-1 3.3 Methodology Following Freeman et al (1982) and Sloan (1996), we estimate the following Equation to test whether information of the persistence of current earnings is reflected in future earnings: 𝑁𝐼𝑖𝑡 = 𝛼0 + 𝛼1 𝑁𝐼𝑖𝑡−1 + 𝜀𝑡 (1) where: 𝑵𝑰𝒊𝒕 : net income of firm i in year t; and 𝑵𝑰𝒊𝒕−𝟏 : net income of firm i in year t-1 However, Equation (1) implies that the coefficients on the cash flows and accruals component in earnings are equal while prior literatures show that accruals are supposed as less qualified than cash flows of earnings Therefore, we use the prior studies’ results as assumption to test for Vietnam stock market to investigate whether earnings persistence is more attributable to accruals or cash flows by following model: 𝑁𝐼𝑖𝑡 = 𝛾0 + 𝛾1 𝐴𝐶𝐶𝑖𝑡−1 + 𝛾2 𝐶𝐹𝑖𝑡−1 + 𝜀𝑡 (2) where 𝑨𝑪𝑪𝒊𝒕−𝟏 is the accruals component of earnings of firm i in year t-1 and 𝑪𝑭𝒊𝒕−𝟏 is the cash flows component of earnings of firm i in year t-1 TIEU LUAN MOI download : skknchat@gmail.com 570 | Policies and Sustainable Economic Development To investigate the persistence of accruals and cash flows, we estimate two coefficients γ1 and γ2 in Equation (2) If γ2 is bigger than γ1, earnings persistence is more attributed to cash flows than to accruals, it means that earnings persistence is rely more on cash flows than accruals component of earnings We follow the empirical model of Mishkin (1983)and Sloan (1996) to test how Vietnamese investors react on the information of earnings persistence by estimating following system Equations: 𝑁𝐼𝑖𝑡 = 𝛼0 + 𝛼1 𝑁𝐼𝑖𝑡−1 + 𝜀𝑡 (1) 𝐴𝑅 𝑖𝑡 = 𝛽(𝑁𝐼𝑖𝑡 − 𝛼0 − 𝛼 1∗ 𝑁𝐼𝑖𝑡−1 ) + 𝜈𝑡 (3) where ARit is the abnormal stock return of firm i in year t The rest of the variables are as previously defined If Vietnamese investors fully understand the information of earnings persistence, then 𝛼1 =𝛼 1∗ , market efficiency is predictably confirmed in Vietnam stock market We also apply test of Mishkin (1983) and Sloan (1996) to identify whether stock prices differentiate implication of accruals and cash flows in earnings persistence by using below system Equations: 𝑁𝐼𝑖𝑡 = 𝛾0 + 𝛾1 𝐴𝐶𝐶𝑖𝑡−1 + 𝛾2 𝐶𝐹𝑖𝑡−1 + 𝜀𝑡 (2) 𝐴𝑅 𝑖𝑡 = 𝛽2 (𝑁𝐼𝑖𝑡 − 𝛾0 − 𝛾 1∗ 𝐴𝐶𝐶𝑖𝑡−1 − 𝛾 ∗2 𝐶𝐹𝑖𝑡−1 ) + 𝜈𝑡 (4) All of the variables are previously defined In estimating these Equations, we could safely conclude that Vietnam stock market correctly reflect the persistence of cash flows and accruals if the persistence of accruals are equivalent (𝛾1 = 𝛾 1∗ ) and the cash flows’ persistence are equal ( 𝛾2 =𝛾 ∗2 ) in the above Equations Empirical Results 4.1 Descriptive statistics Table shows descriptive statistics for firm-year sample used in this study Panel A contains statistics for the components of earnings and abnormal stock return The mean and median value of ACC variable is positive while mean of CF variable is negative, which indicates that listed firms on Vietnam stock market making large investments over the sample period Median value ACC in our test is 0.0836, while median value of ACC documented by Sloan (1996) is negative due to the different accruals definitions Our ACC definition includes the cash flow from financial activities while Sloan excludes it Further, the mean value of CF (-0.0168) is smaller than the mean value of ACC (0.0836), suggesting that over the sample period, earnings are attributable to accruals more than to cash flows TIEU LUAN MOI download : skknchat@gmail.com Policies and Sustainable Economic Development | 571

Variable ACCit-1 CFit-1 NrIit ARit Panel B of Table reports the pairwise Pearson correlations among the variables We observe a strong negative correlation between accruals and cash flows (-0.9002) This negative correlation indicates that the effect of accruals is to eliminate transitory components from cash flows into earnings Accruals are negatively correlated with abnormal stock return (-0.0573), while cash flow is positively correlated with abnormal stock return AR (0.0732) Persistence of earnings and implication of cash flow and accruals components in earnings Firstly, we estimate Equation (1) to find the level of persistence of earnings: NIit = α0 + α1 NIit−1 + εt (1) The result in panel A of Table shows a significant relationship between current earnings and next year earnings with α1 = 0.627, confirming prior findings in Sloan (1996) that current earnings could be an important indicator to predict future earnings Table Persistence of earnings Panel A: Regression

of the result, we use the decile rankings of the tested variables instead of the actual value The ranking formation is built up by assigning each variable from (lowest values) to 10 (highest value) The rank regression estimates are reported in panel B of Table with a slight higher coefficient of α1 (0.648) This parameter estimate confirms the result in panel A is robust Next, we analyze how the persistence of the accruals and cash flows component of earnings being reflected in future earnings by estimating the following Equation: 𝑁𝐼𝑖𝑡 = 𝛾0 + 𝛾1 𝐴𝐶𝐶𝑖𝑡−1 + 𝛾2 𝐶𝐹𝑖𝑡−1 + 𝜀𝑡 (2) Table indicates that the coefficient of the accrual component (𝛾1 ) is 0.570 while the coefficient of the cash flows component (𝛾2 ) is 0.631 This suggests that the accruals component of earnings is less persistent than the cash flow component of earnings Our findings are in agreement with previously studies (Çelik et al., 2013; Dechow et al., 2006; Hong-Bok & Gee-Jung 2010; Navissi et al., 2006; Ozkan & Kayali,

suggests that Vietnam investors not fully capture the quality of earnings, specifically they underestimate the information of earning persistence in their equity pricing The results in panel B of

reports the estimate results of the system of Equations (2) and (4) We observe that the coefficient of accruals, γ1* (0.412) is larger than the coefficient of cash flows γ2* (0.395) It appears that Vietnamese investors overestimate the persistence of accrual components despite the fact that information of accruals is less valuable than cash flow Moreover, the findings of γ1*< γ1 and γ2*< γ2 imply that Vietnamese investors undervalue of the persistence of accruals and cash flows components in earnings We again test for the second hypothesis using the Chi-squared value as a robustness test Clearly, this test strongly rejects the null hypothesis (γ1 = γ1* ; γ2 = γ2*) with a chi-squared of 12.436 and pvalue of 0.002 Hence, the finding suggests that stock prices not reflect fully information in the accrual and cash flow components of earnings Those findings are similar to results of papers using data of developing countries, for example, Navissi et al (2006) using data of Chinese market and Hong-Bok and Gee-Jung (2010) using data of Korean stock market On the contrary, our findings are inconsistent with the results of papers employing data from developed markets In developed markets, investors tend to overprice the persistence of accruals (Sloan, 1996) and correctly price stocks with the persistence of both accruals and cash flows of earnings (Dechow et al., 2006) Conclusion The reliability of accounting information is crucial in equity evaluation This paper investigates the information earnings persistence, properties of its two components (cash flows and accruals) and market pricing of this information in Vietnam, using a data sample of 245 listed firms on the Ho Chi TIEU LUAN MOI download : skknchat@gmail.com Policies and Sustainable Economic Development | 575 Minh City Stock Exchange for the period 2007-2013 Our analysis indicates that past earnings are useful for predicting firms’ future performance Specially, we show that: (i) earnings are persistent and the rate is rather high with the persistence rate is about 0.627; and (ii) the persistence of earnings is shown to be more dependent on the contribution of cash flows than accrual components of earnings Further, this study also examines whether investors correctly anticipate the persistence of current income We also examine the different implication of accruals and cash flows components documented by Sloan (1996) We find that: (i) investors underestimate the persistence of current income into future income; and (ii) investors are not likely to discriminate the level
