Tax Status

We investigate buy–sell imbalances (BSIs) around ex-dividend days on the Taiwan Stock Exchange (TWSE) and find that trading activities are not entirely correlated with investor tax status. We find that margin traders and short sellers engage in arbitrage by selling more stocks for those with high abnormal returns cum- and ex-dividend, respectively. Tax-neutral dealers engage in overnight trading while tax-disadvantaged foreigners refrain from selling stocks cum-dividend.

Weak Form Efficiency

The competence of a financial system is entirely depending upon the stock market efficiency. The gradual growth of equity investor’s participation is inevitable to enrich the overall growth of emerging economies.Hence the necessity is felt to provide an empirical support to the investing community. For the purpose, this study attempts to examine the weak-form efficiency of Indian stock market – National Stock Exchange (NSE). The study has used the daily closing price of the Nifty fifty stocks from 3rdJanuary 2011 to 24thApril 2015. To test the weak form efficiency both parametric and non-parametric tests called Autocorrelation, Augmented Dicky Fuller test, and Runs Test were performed.  The study reveals that 39 stocks of NSE-Nifty Fifty are found to be weak form inefficient, so that the investors can formulate trading strategies to gain abnormal returns. The Index and 10 stocks are found to be weak form efficient during the study period since the price series found to be autocorrelation existence.

Election Results

The study investigates the effect of Presidential election results on the performance of an emerging stock market using the case of the 2011 and 2015 Presidential elections in Nigeria. Adopting Event Study methodology to analyse the secondary data obtained from the Nigerian Stock Exchange (NSE) and some national dailies, the results of the study suggest that the 2011 presidential election result had negative significant impact on the performance of the stock market. On the other hand, the 2015 Presidential election result had positive but insignificant impact on the stock market as evidenced by the average and cumulative abnormal returns on the event date and one day post-event date- an indication that the result of the 2015 Presidential election was a welcomed development as leadership changed from PDP to All Progressives Congress (APC).

Buy Back

Shorting involves selling stocks that one does not own. Advocates of shorting argue that it is needed to make the financial market a two-way (complete) market in which investors with bearish opinions can participate. To gain from shorting, short sellers hope to buy back the shorted stocks at a lower price. Obtaining ‘negative’ alphas or abnormal returns is thus desirable for short sellers as they imply the underperformance of the stocks and that a profit has been realized. Abnormal returns, according to Fama (1998), are anomalies that tend to disappear when reasonable changes are made to the methodology used to measure them. Diamond and Verrecchia (1987), however, theorize and argue a priori that an unusually large increase in short interest will be followed by a period of negative abnormal returns. Short interest is equal to the number of shorted shares divided by the number of shares available to be shorted. Using daily short interest data for stocks traded on the London Stock Exchange for the period of September 2003 to April 2010, we employ an event study to investigate the effects that follow shorting. Alphas and abnormal returns are measured according to the Market Model (MM), the Capital Asset Pricing Model (CAPM) and the Fama–French Three-factor Model (FF3F), and are estimated using different estimation windows of 60 and 120 days. In all the methodologies under study, we find significant negative alphas following shorting.

Using Data

This paper examines the intraday performance of contrarian strategies using data from 438 listed stocks on the Taiwan Stock Exchange in 2004. The results indicate significantly positive abnormal returns for the contrarian strategies. For the whole trading day, the contrarian strategies earn an average abnormal return of at least 0.18% for all strategies, and above 0.3% in 24 out of the 36 contrarian strategies prior to transaction costs. Moreover, the contrarian profit increases from a formation period of five minutes to 10 minutes, and then declines toward a longer formation period of 60 minutes. This pattern suggests that price reversals occur around 10 minutes into the formation period. The intraday analysis also indicates that the abnormal returns earned by the contrarian strategies are higher in the opening and the closing intervals than in the middle of the trading day. Finally, the results indicate that price reversals occur for both prior losers and prior winners, with prior winners experiencing larger price reversals than prior losers when the holding period becomes longer. However, the above results of profitable abnormal returns are based on gross returns before transaction costs were deducted. When reasonable explicit trading costs are considered, none of the 36 contrarian strategies produce any "free lunches" for investors.

We report a numerical study of the Taiwan stock market, in which we used three data sources: the daily Taiwan stock exchange index (TAIEX) from January 1983 to May 2006, the daily OTC index from January 1995 to May 2006, and the one-min intraday data from February 2000 to December 2003. Our study is based on numerical estimates of persistence exponent θp, Hurst exponent H2, and fluctuation exponent h2. We also discuss the results concerning persistence probability P(t), qth-order price–price correlation function Gq(t), and qth-order normalized fluctuation function fq(t) among these indices.

Abnormal Performance

This study examines the cross-sectional determinants of the price reaction to analysts’ recommendations disseminated through various type of media and for firms listed in Taiwan stock markets. We measure abnormal returns using the market model of event study. Based on the type of media (traditional media/social media) and the type of exchange (Taiwan Stock Exchange (TWSE)/Taipei Exchange (TPEx)), we classify the combined sample observations into four samples and run quantile regressions to investigate whether the relation will be uniform across various quantile levels. Our results show that the relation between firm characteristics and cumulative abnormal returns is not homogeneous across various quantiles of abnormal returns. Our evidence indicates that in general the relation tends to be stronger for firms at higher performance quantile levels and tends to be more pronounced for TWSE firms. The strongest relation is found for the Traditional/TWSE sample, where the abnormal returns are positively related to insider ownership and prior-period earnings, and negatively related to institutional shareholding and price-to-book ratio for firms in the highest abnormal performance quantile.

This paper extends ISO certification research by investigating whether a stock value is influenced by the announcement of its ISO registration with respect to the firm size, industry, and ISO standard series on the Taiwan Stock Exchange. The results show that receiving ISO registration influences abnormal returns. The market reacts favorably to both small and large firms but has no reaction to medium firms in terms of a firm's capital. We also observe significant positive market reaction for Plastics and Textiles. A beneficial implication is that investors may benefit more from their investment endeavors if they can properly examine the specific effects.

Stock Market Efficiency

Asset pricing is a key area of literature in analysing and evaluating the stock market efficiency. Though various pricing models made efforts to explain the behaviour of the stocks, the existence of seasonal anomalies in the stock markets creates an opportunity for the investors to generate abnormal returns. The present article emphasizes one of such market anomalies namely, the holiday effect using indices belonging to Indian stock exchanges. Thorough research is performed by including all the prime market-capital and sectoral indices of the National Stock Exchange and the Bombay Stock Exchange. The ARIMAX methodology is adopted to observe the anomaly by considering exogenous variables representing the trading days before the exchange-mandated holidays. Further, the strength of the anomaly is analysed with the incorporation of various stock market reforms and observed to be significantly persistent among most of the Indian market indices (including both the sectoral and the market-capital based indices).
