The Impact

Purpose The purpose of this paper is to investigate the impact of factor-based trading strategies on pricing and volume. Design/methodology/approach The authors employ a regression discontinuity approach to identify abnormalities in volume or pricing around expected portfolio changes. In addition, the authors characterize more granular effects on pricing and volume as a result of portfolio re-classification through Fama and Macbeth (1973) regressions. Findings The authors find that firms which are predicted to transfer among the factor portfolios of Fama and French (1993) exhibit strong and statistically significant short-term variation in stock price and volume. Short-term returns around the cutoff values comprising SMB and HML tend to be temporarily high if the firm is predicted to move into a long component of a factor-mimicking portfolio, and temporarily low if moving into a short component. Similar results are apparent when examining movement in and out of the 25 size and book-to-market sorted test asset portfolios. Practical implications The use of portfolio strategies formulated on the basis of sorting procedures, while once upon a time a niche market in the portfolio management industry, is now ubiquitous. The results of this study raise interesting methodological questions about the pricing implications arising from these common methodologies. Originality/value This study makes a number of contributions. First, it contributes to the idea that the publication or dissemination of trading strategies or – more generally – common portfolio sorting methods, leads to effects on pricing and volume through commonly motivated trading pressure. In other words, recipe-like discoveries of advantageous trading strategies lead to a synthetic creation of demand. Second, by noting that a lot of factor-focused trading activity begins around July and August of each year, the study relates to existing literature which documents seasonal variation in stock returns and volume. The findings raise questions about what guides institutional investors’ portfolio allocation decisions and whether these are optimal in aggregate.

AbstractThis research explored the effects of the coronavirus disease (COVID-19) outbreak on stock price movements of China’s tourism industry by using an event study method. The results showed that the crisis negatively impacted tourism sector stocks. Further quantile regression analyses supported the non-linear relationship between the government’s responses and stock returns. The results present that the resurgence of the virus in Beijing did bring about a short-term negative impact on the tourism industry. The empirical results can be used for future researchers to conduct a comparative study of cultural differences concerning government responses to the COVID-19.

Practical Implications

PurposeThis study compares the impact of the COVID-19 pandemic on stock returns in the first two waves of infection across selected markets, given built-in corporate immunity before the global outbreak.Design/methodology/approachThe data are collected from listed firms in five markets that have experienced the second wave of COVID-19 contagion, namely the United States (US), Australia, China, Hong Kong and South Korea. The period of investigation in this study ranges from January 24 to August 28, 2020 to cover the first two COVID-19 waves in selected markets. The study estimates the research model by employing the ordinary least square method with fixed effects to control for the heterogeneity that may confound the empirical outcomes.FindingsThe analysis reveals that firms with larger size and more cash reserves before the COVID-19 outbreak have better stock performance under the first wave; however, these advantages impede stock resilience during the second wave. Corporate governance practices significantly influence stock returns only in the first wave as their effects fade when the second wave emerges. The results also suggest that in economies with greater power distance, although stock price depreciation was milder in the first wave, it is more intense when new cases again surge after the first wave was contained.Practical implicationsThis paper provides practical implications for corporate managers, policymakers and governments concerning crisis management strategies for COVID-19 and future pandemics.Originality/valueThis study is the first to evaluate built-in corporate immunity before the COVID-19 shock under successive contagious waves. Besides, this study accentuates the importance of cultural understanding in weathering the ongoing pandemic across different markets.

Stock Momentum

Purpose This paper aims to examine the impact of the dividend payout ratio on future stock returns and momentum strategies. Design/methodology/approach The author uses the portfolio sorting approach used in the momentum literature to examine this impact. Findings First, the author shows that the returns for the winner stocks tend to be the largest if no dividends are paid and then decrease with the dividend payout ratio; the returns for the loser stocks tend to have an inverted U-shaped relationship with the dividend payout ratio, but the zero-dividend loser stocks have the smallest return; and the returns for the stocks between the winners and the losers tend to remain similar, regardless of the dividend payout ratio. Second, the author shows that momentum profit is the largest for the stocks that do not make dividend payment but appear similar for the stocks that pay dividends. The author's empirical findings imply that stock price momentum is a function of the dividend payout ratio, growth stock momentum tends to be much stronger than value stock momentum and no-dividend stock momentum beats dividend stock momentum. In fact, when the dividend payout ratio is considered, momentum profit can be improved by up to 63 per cent. Originality/value This paper is the first one to examine the impact of dividend payout ratios on future stock returns and momentum profit, and it obtained many interesting empirical results. In addition, unlike most studies in the momentum literature that use behavioral theory to explain empirical findings, this paper uses the growth option idea to present a rational explanation for the empirical results in this paper.

The Impact

PurposeThe current study aims to achieve two targets. First, examine empirically that whether corporate managers use tax avoidance to influence short-term profitability? Second, investigate the impact of tax avoidance on the value of firms. The tax accounts provide the opportunity to influence temporary/permanent profitability but empirical studies overlooking this matter, particularly in emerging economies.Design/methodology/approachFirst, the authors identified unexpected fluctuations of tax avoidance and then examine whether it impacts the profitability signal and firms' value? The unbalanced panel data of 189 non-financial firms for the period 2000–2018 are used for empirical analysis. The estimation biases and results consistency are verified by using two different econometric models including generalized least square and two-stage least squareFindingsThe study identifies that managers manipulate the profitability signal through tax avoidance. Tax avoidance practices help in earning management and earning smoothing to avoid negative signals in the stock market. In line with the behavioral finance view, tax avoidance has a positive impact on current stock returns because investors focus on profitability without a detailed screening of cash flows.Originality/valueA limited number of studies investigate the use of tax avoidance for manipulation of the short-term earning signal. Identifying gaps and limitations in the literature, this study provides invaluable insights into tax avoidance and its association with the profitability and value of firms. The findings are important for investors, managers and policymakers in making portfolio decisions and corporate policies.

Purpose The purpose of this paper is to examine the relationship between the strength of corporate governance and the value of firm-level investment policies following the passage of the Sarbanes–Oxley (SOX) Act of 2002 and the associated changes to the listing requirements of major stock exchanges. In particular the authors seek to examine potential changes in the market’s assessed value of capital expenditures after the passage of the SOX Act relative to before. Design/methodology/approach The authors employ a difference-in-difference methodology, centred on the year of the passage of the SOX Act to test for the role of governance on the marginal value of capital expenditures. Excess stock returns are calculated by subtracting Fama and French (1993) size and book-to-market portfolio value-weighted returns from the firms’ annual stock returns. Each firm is grouped into one of 25 size and book-to-market portfolios for each year in the sample, with size and the book-to-market ratio proxying for sensitivity to common risk factors in stock returns (Fama and French, 1993). Findings The authors find that markets responded to the change in governance brought about by the new regulation by altering the value of firm-level capital expenditures in a way that is generally consistent with predictions of agency theory. While the overall findings imply a reduction in agency conflicts post-SOX, there is some evidence that certain firms may have suffered excessive costs of compliance, while still others saw managers become excessively risk averse. Research limitations/implications The study has implications related to the efficacy of legislation. Cross-sectional variation in the effect of SOX on the marginal value of capital expenditures suggests that one-size-fits-all legislative approach can have both expected as well as unintended consequences. The study limits its analysis to examining the impact of three significant provisions of the Act. While, the value implications of the Act are largely captured by the selected three, a more comprehensive study could expand on the set of provisions studies to obtain a more granular level impact. Practical implications This research should add to the growing body of the literature examining the effect of SOX on firms’ real activities and decisions, as well as contribute to the debate on whether the Act was beneficial or costly to firms. With particular reference to the impact of capital expenditure on firm value, the research contributes to the sparse literature examining the contribution of capital expenditures to firm value and the role that agency conflicts play in this relationship. Additionally, this research adds to the growing body of the literature that examines the costs and benefits of the sweeping new regulations brought on by the adoption of SOX. Social implications Given the importance of investment policy for economic productivity and growth, the insights provided by findings in this research should benefit lawmakers both within the USA as well as in countries where corporate misconduct and fraud is a concern. Originality/value This is the first study that examines the impact of the SOX Act on the way capital markets value firm-level investment in capital expenditures. Since use of corporate resources by managers is fraught with agency conflicts, the role of SOX in potentially alleviating this conflict as revealed by the tests in this study are very valuable.

PurposeThis paper explores the effects of US President Donald Trump's Twitter messages (tweets) on the stock prices of media and non-media companies.Design/methodology/approachThe authors’ empirical analysis considers all Twitter messages posted by Donald Trump from May 26, 2016 (the date he passed the threshold of 1,237 delegates required to guarantee his presidential nomination) to August 30, 2018. The authors accessed President Trump's tweets through http://www.trumptwitterarchive.com, which provides links to all Twitter messages the President has ever posted. Of the 6,983 presidential tweets during our sample period, the authors select 513 messages that mention companies that are publicly traded in the United States for this study. The selected messages are then classified as having a positive, neutral or negative sentiment. The authors employ a series of univariate and multivariate tests as well as Heckman two-step regressions and partial least squares regressions to examine the effect of the President's tweets on the stock prices of the firms he tweets about.FindingsFor media firms, the authors find that positive tweets have a pronounced positive stock price impact, whereas negative and neutral tweets have little or no effect. For non-media firms, the authors observe the opposite: negative tweets tend to be associated with significant stock price declines, whereas neutral and positive tweets incur weakly positive stock price reactions. To a large extent, these stock price declines reverse on the following day. The authors further find that the President's reiteration of information that is already known by the market incurs an additional stock price reaction. The President's attitude towards the news appears to play a major role in this context.Originality/valueThe authors contribute to the literature by offering various new insights regarding the effect social media has on the stock markets. In addition, this paper expands the emerging strand of literature that explores how President Trump affects the stock prices of firms he tweets about. This paper differs from prior studies in this area by considering a broader range of tweets, by controlling for potential selection biases, by differentiating between Trump's tweets about media and non-media firms and by exploring the impact of “old” vs “new” news based on whether the President repeats information that is already known to the market. If social media posts by single influential people are found to affect markets, they may create trading opportunities for investors and financial managers and risk arbitrage opportunities for arbitrageurs. In the political science field, the findings of this research provide valuable insights into how politicians can employ social media platforms to affect the public, and the differential influence of nominees and politicians in office. Finally, our study gives corporations that wish to back a certain campaign or a candidate in an election a better idea of the possible risks and benefits of their actions, considering that candidates or politicians could post negative messages on social media platforms targeting companies that backed their opponents.

Purpose – The purpose of this paper is to examine the impact of Broad-Based Black Economic Empowerment (BBBEE) on the risk and returns of listed and delisted property firms on the Johannesburg Stock Exchange (JSE). The study was investigated to understand the impact of Black Economic Empowerment (BEE) property sector charter and effect of government intervention on property listed markets. Design/methodology/approach – The study examines the performance trends of the listed and delisted property firms on the JSE from January 2006 to January 2012. The data were obtained from McGregor BFA database to compute the risk and return measures of the listed and delisted property firms. The study employs a capital asset pricing model (CAPM) to derive the alpha (outperformance) and beta (risk) to examine the trend amongst the BEE and non-BEE firms, Sharpe ratio was also employed as a measurement of performance. A comparative study is employed to analyse the risks and returns between listed property firms that are BEE compliant and BEE non-compliant. Findings – Results show that there exists differences in returns and risk between BEE-compliant firms and non-BEE-compliant firms. The study shows that BEE-compliant firms have higher returns than non-BEE firms and are less risky than non-BEE firms. By establishing this relationship, this possibly affects the investor’s decision to invest in BEE firms rather than non-BBBEE firms. This study can also assist the government in strategically adjusting the policy. Research limitations/implications – This study employs a CAPM which is a single-factor model. Further study could employ a multi-factor model. Practical implications – The results of this investigation, with the effects of BEE on returns, using annualized returns, the Sharpe ratio and alpha (outperformance), results show that BEE firms perform better than non-BEE firms. These results pose several implications for investors particularly when structuring their portfolios, further study would need to examine the role of BEE on stock returns in line with other factors that affect stock returns. The results in this study have several implications for government agencies, there may be the need to monitor the effect of the BEE policies on firm returns and re-calibrate policies accordingly. Originality/value – This study investigates the performance of listed property firms on the JSE which are BEE compliant. This is the first study to investigate listed property firms which are BEE compliant.

Purpose: A green bond is a financial instrument issued by governments, financial institutions and corporations to fund green projects, such as those involving renewable energy, green buildings, low carbon transport, etc. This study analyses the effect of green-bond issue announcement on the issuer’s stock price movement. It shows the reaction of the stock price after the issue of green bonds. Methodology: This study is based on secondary data. Green-bond issue dates have been collected from newspaper articles from different online sources, such as Business Standard, The Economic Times, Moneycontrol, etc. The closing prices of stocks have been taken from the NSE (National Stock Exchange of India Limited) website. An event window of 21 days has been fixed for the study, including the 10 days before and after the issue date. Data analysis is carried out through the event study method using the R software. Calculation of abnormal returns is done using three models: mean-adjusted returns model, market-adjusted returns model and risk-adjusted returns model. Findings: The results show that the issue of green bonds has a significant positive effect on the stock price. Returns increase after the green-bond issue announcement. Although the announcement day shows a negative return for all the samples taken for the study, the 10-day cumulative abnormal return (CAR) is positive. Thus, green-bond issues lead to positive sentiments among investors. Research implications: This research article will help the government issue more green bonds so that the proceeds can be utilized for green projects. The government should motivate corporations and financial institutions to issue more green bonds to help the economy grow. In India, very few organizations have issued a green bond. It will be beneficial if these players issue green bonds, as it will increase the firms’ value and boost returns to the investors. Originality/value: The effect of green-bond issue on stock returns has been analysed in some studies in developed countries. This is the first study to examine the impact of green-bond issue on stock returns in the Indian context, to the best of our knowledge.

Purpose This paper aims to analyze the dynamics of the security lending process and lending markets to identify the market-wide variables reflecting the characteristics of the stock borrowed and to measure the credit risk arising from lending contracts. Design/methodology/approach Using the data provided by Istanbul Settlement and Custody Bank on the equity lending contracts of Securities Lending and Borrowing Market between 2010 and 2012 and the data provided by Borsa Istanbul on Equity Market transactions for the same timeframe, this paper analyzes whether stock price volatility, stock returns, return per unit amount of risk and relative liquidity of lending market and equity market affect the defaults of lending contracts by using both linear regression and ordinary least squares regression for robustness and proxying the concepts of relative liquidity, volatility and return constructs by more than variable to correlate findings. Findings The results illustrate a statistically significant relationship between volatility and the default state of the lending contracts but fail to establish a connection between default states and stock returns or relative liquidity of markets. Research limitations/implications With the increasing pressure for clearing security lending contracts in central counterparties, it is imperative for both central counterparties and regulators to be able to precisely measure the risk exposure due to security lending transactions. The results gained from a limited set of lending transactions merit further studies to identify non-borrower and non-systemic credit risk determinants. Originality/value This is the first study to analyze the non-borrower and non-systemic credit risk determinants in security lending markets.

PurposeThis study investigates the Chinese stocks' returns during different epidemic periods to assess their effects on firms' market performance.Design/methodology/approachThe study employs an event study method on more than 3,000 firms listed on Shanghai and Shenzhen stock exchanges during periods of SARS, H5N1, H7N9 and COVID-19FindingsEpidemics' effect on firms' stock returns is persistent up to 10 days after the event dates. Although the impact varies with types and development of the disease, most firms experience a negative impact of the epidemics. Among the epidemics, COVID-19 has the greatest impact, especially when it grows into a pandemic. The epidemics' impact is uneven across industries. In addition, B-shares and stocks listed on Shanghai Stock Exchange are more negatively influenced by the epidemic than A-shares and those listed on Shenzhen Stock Exchange.Research limitations/implicationsThe results of the study contribute to the limited literature on the effects of disease outbreaks as an economic shock on firm market performance. Given the possibility of other epidemics in the future, the study provides guidance for investors in designing an appropriate investing strategy to cope with the epidemic shocks to the market.Originality/valueThe research is novel in the way it compares and assesses the economic impact of different epidemics on firms and considers their impact at different development stages.
