This study analyzes price-volume relation for Taiwanese listed firms that are added to or deleted from the MSCI free indices in the sampling period from May 17, 1999 to May 21, 2001. Additions to the indices found a positive abnormal return of 3.9% in the run-up window from the announcement day up to one day before the change was implemented. This was followed by a significant reversal on the change day. The deleted firms exhibit an even stronger announcement effect, with a significant abnormal return of -9.1% in the run-up, followed by a reversal of 1.6% on the change day. Even when reversals occurred on the change day, the abnormal returns in the post-announcement window are positive for additions and negative for deletions. The results support the price-pressure and long-run downward-sloping-demand hypothesis and are inconsistent with the efficient market hypothesis. The abnormal trading volume for deletions is negative following the announcement, contradicting the findings of Lynch and Mendenhall (1997). This difference is due to the innate of the Taiwanese stock market, in which no dedicated market makers accommodate block trading. Moreover, the regression results confirm a positive volume-return relation before and a negative relation on and after the change day. Finally, the QFII net buy (sell) the added (deleted) stocks up to ten days after the change was implemented, while the Securities Investment Trusts and Securities dealers, having a shorter frame net, buy the added stocks up to two days after the effective change. Individual investors reversing position on the change day are responsible for the price reversal on the change day.

The study explores the correlation between the immediate and the longer-term stock returns following large daily price moves. Following the previous literature, which documents a tendency for price reversals after initial large price moves, I suggest that if a large stock price move is immediately followed by a short-term price drift, then it may indicate that the company-specific shock is more completely incorporated in the stock price, significantly increasing the probability of subsequent longer-term price reversal. Analyzing a vast sample of large stock price moves, I document that negative (positive) longer-term stock price reversals after large price increases (decreases) are significantly more pronounced if the latter are immediately followed by relatively high (low) short-term cumulative abnormal returns, that is, by short-term price drifts. The effect remains significant after accounting for additional company-specific (size, market model beta, historical, or conditional volatility) and event-specific (stock’s return and trading volume on the event day) factors.

This study intends to examine the differences in market reaction around the announcement of the Annual Report Award which is not only measured by abnormal return but is also measured using trading volume activity and stock prices. The data used are quantitative data in the form of a list of companies that received the Annual Report Award for the 2015-2018 period, the daily closing price of the ARA-winning company in the event window, the composite stock price index, the number of shares traded, and the number of shares outstanding. The event window is selected for 11 days because the long window period will blend with the effects of other events or confounding effects. The results of the study concluded that the market reacted around the announcement of the Annual Report Award for the 2015-2018 period measured using abnormal returns, trading volume activity, and stock prices. There is no difference in abnormal returns before and after the announcement of the 2013-2016 Annual Report Award period. Instead there are differences in trading volume activity and stock prices before and after the announcement of the Annual Report Award for the 2015-2018 period.

This research was conducted to see the effect of the implementation of the Employee Stock Ownership Program on average abnormal returns of banking companies before and after applying ESOP and trading volume. The aim is to find out the difference in average abnormal return before and after applying the ESOP. The variable used in this study is average abnormal return. The period of this research event is 20 days, 10 days, 5 days and 1 day which are divided before and days after the date of application. This study examines banking companies that apply the Employee Stock Ownership Program listed on the Indonesia Stock Exchange so that data is obtained from trading in the company's stock price. The sampling criteria used a purposive sampling method in order to obtain 9 samples. The hypothesis method used in the normally distributed data is Paired Samples T-test. The result is that all average abnormal return periods both on the first and the last date of the ESOP application have a significant value >0.05, which means that the entire event period of the variable is proven to have no significant difference both before and after the banking company applies the Employee Stock Ownership Program.

From anticipation to anxiety in a market for lottery-like stocks

Purpose – The purpose of this paper is to investigate a unique sample of lottery-like stocks and contextualize their short-run price behavior with respect to behavioral principles. Design/methodology/approach – The authors conduct a short-run event-study of the abnormal returns for stock market investments in Australian small-cap oil and gas (O & G) explorers centered on the drilling commencement (spudding) of 157 wildcat oil or gas wells drilled between January 2000 and June 2010. Findings – Small-cap stock market investments associated with newly spudded wildcat O & G wells are negative NPV gambles rather than fair (zero NPV) investments. Once a wildcat well is spudded, the 30-day expected abnormal return is 6-8 percent: wealth-maximizing stockholders are advised to sell upon news of spudding, but gamblers may wish to hold on for the chance of a 10.6 percent 30-day average abnormal return (if the well is not plugged and abandoned). In the lead-up to each gamble the authors observe a significant pre-spudding stock price run-up on average, perhaps indicative of positively affected investors aroused by an easily imagined successful wildcat gusher as per evidence on the influence of image and affect on investors’ decisions (MacGregor et al., 2000; Loewenstein et al., 2001; Rottenstreich and Hsee, 2001; Peterson, 2002). Originality/value – The wildcat drilling events considered in this paper are lottery-like by nature, and spudding represents the distinct moment when the gamble is unambiguously on, following shortly on from which investors either strike it lucky or strike out. The specifically small-cap wildcatters are typically heavily vested in one well at a time, therefore the sample stocks are uniquely lottery like. This differs from other studies which infer the lottery-like nature of their sample stocks from characteristics such as price and idiosyncratic volatility.

This study conducted the examination of the long-run performance of IPO stocks in the Japanese market by measuring the monthly AAR/CAAR of sample IPO stocks. The study did this, so as to investigate whether IPO stocks in the Japanese market outperform in the long-run, as prior research on this phenomenon in the US market (Ritter, 1991; McDonald and Fisher, 1972) had found. The finding is that on the one hand, at TOPIX and TSE-2ND, stocks IPO firms that went public during 2004 to 2011 did not underperform the market in the long-run, as the monthly CAAR of sample IPO stocks on month 36 was not statistically significant. On the other hand, the finding also reveals that at MOTHERS, IPO firms underperformed the market throughout the period between months 2 and 36, and the monthly CAAR of IPO stocks at this market was –30.08 percent on month 36. The implication of this finding for the Efficient Market Hypothesis is that market efficiency held well at TOPIX and TSE-2ND; where during the sampling period abnormal returns could not be achieved and thus the long-run IPO underperformance was unlikely to occur. On the contrary, the departure from market efficiency was observed at MOTHERS: In the long-run, IPO stocks kept experiencing negative abnormal returns, and the existence of the long-run IPO underperformance was found to be significant.  Long-run IPO underperformance did not exist, with only one exception: It is only at MOTHERS that the long-run IPO underperformance was observed, whereas at TOPIX and TSE-2ND the phenomenon was not observed.

Name Changes

Purpose The purpose of this paper is to examine stock price and trading volume reactions to name changes of the Toronto Stock Exchange listed companies. Previous studies present conflicting evidence on reactions to corporate name changes in US and other capital markets. Design/methodology/approach This study uses the event study methodology to calculate abnormal returns and trading volume around the announcement, approval, and effective dates of corporate name changes. It also contrasts abnormal returns between major and minor name changes, signaling focused and diversified strategies, accompanied with a ticker symbol change and without a ticker change, structural and pure name changes, as well as brand adoption and radical name changes. Findings Companies tend to experience a significant run-up in stock price in the period preceding the announcement of a name change. The stocks also show a significant positive abnormal return around the effective date. In addition, corporate name changes are associated with significant increases in trading volume for several days starting from the approval date. Most importantly, the type of a name change matters, as reflected in significance levels of abnormal return and trading volume reactions to various types of corporate name changes. Research limitations/implications The limitation of this study comes from the difficulty to precisely identify the date when the market learns about a possible corporate name change. Originality/value This study is the first to examine market reactions to name changes of Toronto Stock Exchange listed companies. Most importantly, whereas previous studies focus on the announcement day, this paper also considers the approval and effective days. It also contrasts responses between name changes accompanied with a new ticker and name changes without a ticker change.

The efficient market hypothesis implies that no investor can get an abnormal return. This hypothesis has become a research topic that many researchers refer to. However, this hypothesis is strongly refuted after the discovery of several anomalies that are inconsistent with the efficient market hypothesis. One of them was found by De Bondt and Thaler (1985), that stock prices have a certain tendency, namely that stocks that perform well in one period will become stocks that perform poorly in the next period. Vice versa. This phenomenon is called overreaction or overreaction. These findings motivated further researchers to apply contrarian strategies to gain an advantage when there was an overreaction. This research is a study that is intended to obtain evidence of the ability of contrarian strategies in obtaining abnormal returns. This study aims to analyze the occurrence of overreaction on stocks on the Indonesia Stock Exchange and to analyze the advantages of implementing a contrarian strategy for investors. This research was conducted at companies listed on the Indonesia Stock Exchange. The companies selected were 100 companies with the most active transactions during 2019. From the results of data analysis, it can be concluded that there was a price reversal for the shares listed on the Indonesia Stock Exchange. This result is quite strong because it has been tested for up to 4 weeks. Despite the price reversal, the contrarian strategy was not able to generate significant returns for investors.Keywords :contrarian strategy, abnormal return, overreaction

One of the highly controversial issues in the area of finance is “Efficient Market Hypothesis”. Efficient Market Hypothesis states that, “In an efficient market, all available price information is reflected in the stock prices and it is not possible to generate abnormal returns compared to other investors.” A lot of studies conducted previouslyto test the Efficient Market Hypothesis, confirmed the theory until recent years, when some academicians found it to be non-applicable in financial markets. According to them, it is possible to forecast the stock price movements using Technical Analysis. The results of various studies have been inconclusive and indefinite about the issue. This study attempted to test the efficiency of FMCG Sector stocks in India in its weak form. For the study, closing prices of top 10 stocks from Nifty FMCG index has been taken for the 5-year period ranging from 1st October 2014 to 30th September 2019. Wald-Wolfowitz Run test has been used to test the haphazard movements in the stock price movements. The results indicated that FMCG sector stocks does support the Efficient Market Hypothesis and exhibit efficiency in its weak form. Hence, it is not possible to accurately predict the price movements of these stocks.

The behavioral finance literature has documented that individual investors tend to sell winning stocks more quickly than losing stocks, a phenomenon known as the disposition effect, and that such a behavior has an impact on stock prices. We examined this effect in the Tunisian stock market using the unrealized capital gains/losses of Grinblatt & Han (2005) to measure the disposition effect. We find that the Tunisian investors exhibit a disposition effect in the long-run horizon but not in the short and the intermediate horizons. Moreover, the disposition effect predicts a stock price continuation (momentum) for the whole sample. However this impact varies from an industry to another. It predicts a momentum for “manufacturing” but a return reversal for “financial” and “services”.

This study aims to analyze the abnormal returns before and after the announcement of mergers and acquisitions in the companies listed on the IDX 2018. In this study the observation period taken was three days before and after the announcement of mergers and acquisitions with the number of samples observed were 9 companies. The method for calculating abnormal returns used is the market adjusted return by using an intraday stock price of 15 minutes. Based on testing hypotheses conducted by paired sample t-test, it was found that there were no significant differences in abnormal returns before and after the announcement of mergers and acquisitions in each 15 minute period.
