Positive Abnormal Return

This study investigates the price and volume behavior of stock added and excluded to the IBOVESPA, IBrX50, and IBrX100 indexes during the years 1994 to 2002 and FGV100 index during the years 2000 to 2002. In contrast to findings in the US, we find no evidence of abnormal returns around the announcement of changes in the IBOVESPA. We find short-term positive abnormal return to stocks added to the IBOVESPA and IBrX50. There is evidence of negative cumulative returns for stocks excluded from the indexes. We also find positive abnormal trade volume on the date before the stocks were added to the IBOVESPA index.

Purpose – This paper aims to investigate the impact of the filing of Form 20-F to the Securities and Exchange Commission (SEC) on short-term trading volume and return by those foreign firms which list their securities in the US Stock Exchanges. Design/methodology/approach – The authors collected 402 American depository receipt (ADR) firms from 38 different countries that listed their securities in the US Stock Exchanges over a 10-year period of 2000-2009. A regression model was used to examine such impact, including the post year 2007 SEC elimination of reconciliation. Findings – This paper found significant abnormal trading volumes and abnormal returns one day, two days and three days following the 20-F report for the sample firms whose financial statements were prepared under both home-country accounting principles and US generally accepted accounting principles (GAAP). Firms originally using international financial reporting standards (IFRS) do not present abnormal return and abnormal trading volume. This indicates that US investors view IFRS to be as high-quality as US GAAP. Research limitations/implications – The findings might be limited to this period and might not draw statistical inference for the future period. This evidence offers support for the SEC’s elimination of the reconciliation requirement to US GAAP. Practical implications – This study was carried out with the aim to investigate whether the release of Form 20-F by ADR firms offers any additional information useful to investors incorporating both abnormal return and trading volume, which is thought to be more sensitive. Originality/value – This paper investigates the short-term return and volume reactions caused by the earnings and equity reconciliation from home-country accounting standards or IFRS to US GAAP for foreign cross-listed firms in the USA.

In today’s interrelated economies, financial information travel at speed of light to reach investors around the globe. Global financial markets experience regular shocks that transmit negative waves to other equity markets and different asset classes. Given the unique characteristics of exchange-traded funds (ETFs), this paper examines how different ETFs that are traded on London Financial center reacted to the Brexit event in 23 June 2016. The unexpected referendum result the day after is viewed as the next significant financial event since 2008. The paper employs an event study market model on daily and abnormal returns of the selected ETFs with respect to FTSE 250 around the event date. Contrary to what is expected, the world equities fund experienced significant positive abnormal return on the event day. Emerging markets again proved to be a preferred investment destination in times of financial turmoil; the emerging equities fund gained 3% while enjoying an 11.5% positive significant abnormal returns. The US T-Bond fund recorded a 9% return with a significant 7.2% abnormal return. The gold fund soared as much as 4% as investors seeks refuge from Brexit, and the oil fund retraced 1% amid concerns of slowing global demand.

This paper examines the market response surrounding the share repurchase announcements of Malaysia Listed Companies from years 2012 to 2016. One sample T-test was carried out to identify the abnormal return in the range before and after 20 days from share repurchase announcements. The result shows a significant positive abnormal return in the day of repurchase announcements and continuously until day 1 after the announcements. Multiple regression analysis was performed in order to identify the firm characteristic of share repurchase. The finding is supported with information asymmetric, which shows that stock market reacts more favorably through the repurchase announcements by small firms than large firms. This study is consistent with the signaling hypothesis that shows share repurchase announcement can be an effective tool in stabilizing the stock market in Malaysia. The finding of this study acts as a useful tool for managers and investors to improve their decisions on share repurchase announcements in Malaysia. Company’s managers can conduct share repurchase announcements that are able to make the stock market react positively in order to generate positive abnormal returns.

Purpose: The core purpose of this paper empirically study of the initial public offerings (IPOs) of companies accepted in oil and chemical industries. The paper attempts to answer the question of is there any abnormal return from IPOs in listed companies in Tehran Stock Exchange (TSE).Design/methodology/approach: This research is an applied research, and its design is empirical, which is done by the method of post-event (past information). For the purpose of the study the t-statistic, regression and variance analyses are applied to examine the hypotheses. We use in the analyses a sample of 29 newly accepted Iranian oil and chemical companies listed on TSE for the period of 2001 to 2012. This paper has studied abnormal return and three abnormal phenomena have been considered in capital market. These phenomena consist: (1) underpricing or overpricing of the firm's stock, (2) lower or higher stock return of the firms and (3) Particular period in market for stock transactions volume.Findings: The results support the hypothesis that there is a positive abnormal return to investing in the newly accepted oil and chemical firms for stockholders. It also shown the firm size is the only factor that can affect the stock abnormal return. With considering significance level, investors have to give attention sequentially to other variables such as stock ownership centralization, going public time and stock offering volume.

Relative Spread

AbstractStock split ex-dates are associated with both an increased intensity of small investor buying and a positive abnormal return. The broker promotion hypothesis suggests that the increase in relative spread after a split induces brokers to promote splitting stocks to small investors. The trading inconvenience hypothesis ascribes the ex-split effects to inconveniences such as investors' aversion to dealing with due bills, which is unrelated to relative spreads. The reduction in the bid-ask spread due to decimalization allows us to disentangle these two hypotheses. During the 1/8th pricing period, we show that after the ex-date, the relative spread increases significantly. The average buy order size decreases and the frequency of small transactions increases after the split. After decimalization, these changes are smaller in magnitude. We observe significant positive abnormal returns around the ex-date during the 1/8th pricing period, but not in the decimal pricing period. These results support the broker promotion hypothesis.

Contrarian Strategies

Capital market efficiency and the prediction of future stock prices are the most thought-provoking and ferociously debated areas in finance. The followers of traditional financial theory strongly believe that the markets are efficient in pricing the financial instruments. This view became popular after Fama’s work on the Efficient Market Hypothesis. But before 1990s, wide-ranging financial literature documented that stock prices, to some extent, are predictable. Many psychologists, economist and the journalists are of the view that general tendency of individuals is to overreact to the information. De Bondt and Thaler (1985) studies this view of experimental psychology that whether such behaviour matters at the market level or not. They found out that stock prices will overreact to information, and suggested that contrarian strategies buy the past losers and sell the past winners, earn abnormal returns. They extended the holding period from 3 to 5 years and provide the evidence of long term returns reversal. Jegadeesh (1990) and Lehmann (1990) supported the evidence of return reversal in short term, i.e. from one week to one month. They suggested that the contrarian strategies having holding period of one week to one month earned the significant abnormal return. Lo and Mac Kinalay (1990) objected on the ground that a major portion of this abnormal return, reported by Jegadeesh (1990) and Lehmann (1990), is due to the delayed reaction of stock prices to common factors rather than to overreaction. Some other researchers pointed out some other reasons of this abnormal stock returns i.e. short-term pressure on stock prices and absence of liquidity in the market rather than overreaction.

The main objective of this study is to examine empirically the signalling theory for a sample of firms listed at Amman Stock Exchange (ASE) during the period 2005 to 2010. The sample consists of 183 observations and 132 observations for dividend release sample and no-dividend release sample, respectively. Event Study Methodology (ESM) is applied to examine the market reaction to dividend release announcements. The market model is used to generate the expected returns. Also, the t-test is used to examine the significance of the mean and cumulative abnormal returns. Results from the dividend release sample shows that there is a significant positive abnormal return on the announcement days. Also, it shows that there is an overreaction straight after the announcement day, then a correcting attempt in the post event and then it goes back to normal, which is consistent with the signalling hypothesis. For the no-dividend release sample, the results show no significant abnormal return on and around the announcement days which is again consistent with the signalling hypothesis. Our results are consistent with Al-Shattarat et al. (2012) suggestions that there could be value relevance for dividends rather than dividends change. Our findings show that there is value relevance for dividends and thus supporting the signalling hypothesis.

The objective of this study is to determine whether companies listed on the Johannesburg Stock Exchange overreacted to unexpected favourable and unfavourable company-specific news events during the period 1970 - 1984. The JSE appears to be inefficient in reacting to the announcement of unfavourable news; economically significant abnormal returns up to one year following the event are observed. The JSE does not appear to overreact to news of a favourable nature, there is only weak evidence of short-term overreaction. The selling pressure caused by panic selling could depress prices well below levels justified by the unfavourable news. The magnitude of the overreaction to unfavourable news is sufficient to enable astute investors to outperform the market by taking positions in these securities. Knowledge of the pattern of market overreaction can also be of value to investors for transactions that are to take place anyway.
