PROFITABILITAS STRATEGI KONTRATRIAN DI BURSA EFEK INDONESIA

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

Herding and Contrarianism: A Matter of Preference?

Herding and contrarian strategies produce informational ineffciencies when investors ignore private information, instead following or bucking past trends. In a simple market model, I show theoretically that investors with prospect theory preferences generically follow herding or contrarian strategies, but do so because of future returns as opposed to past trends. I conduct a laboratory experiment to test the theory and to obtain an estimate of the distribution of preferences in the subject population. I find that approximately 70% of subjects have preferences that induce herding. Using the preference estimates, I quantify informational effciencies and predict trade behavior in more general environments.

Impact of Credit Risk on Momentum and Contrarian Strategies: Evidence from South Asian Markets

We examine the profitability of the momentum and contrarian strategies in three South Asian markets, i.e., Bangladesh, India, and Pakistan. We also analyze, whether credit risk influences momentum and contrarian return for these markets from 2008 to 2014. We use default risk that relates to non-payments of debts by firms as a measure of credit risk. For that purpose, we use distance to default (DD) by Kealhofer, McQuown, and Vasicek (KMV) model as a proxy of credit risk. We calculate the credit risk and form the momentum and contrarian strategies of the firms based on high, medium, and low risk. We find that in all three markets, the momentum and contrarian returns are significant for medium and high credit risk portfolios and no momentum and contrarian returns for low credit risk portfolios.

A Novel Online Portfolio Selection Strategy with Multiperiodical Asymmetric Mean Reversion

Mean reversion is an important property when constructing efficient contrarian strategies. Researchers observe that mean reversion has multiperiodical and asymmetric nature simultaneously in real market. To better utilize mean reversion and improve the existing online portfolio selection strategies, we propose a new online strategy named multiperiodical asymmetric mean reversion (MAMR). The MAMR strategy incorporates a multipiecewise loss function with the moving average method and then imitates the passive-aggressive algorithm. We further provide a solution via convex optimization. This strategy runs in linear time and thus is suitable for large-scale trading applications. Our empirical results testing six real market datasets show that this strategy can achieve better results in bearing higher transaction cost.

Destabilizing momentum trading and counterbalancing contrarian strategy by large trader groups

Purpose The purpose of this paper is to assess trading strategies adopted by each large trader group and examine their effects on the volatility in the interest rate futures markets. Design/methodology/approach The Grinblatt et al.'s (1995) measure of momentum strategy is used to estimate the degree momentum and contrarian strategies. Then, regression analysis is used to determine the effects of trading strategies on volatility. Findings Up until 2005, the trades by non-clearing member firms in the futures market were separated from institutional traders providing us the opportunity to study trading strategies adopted by large distinct trading groups and its effects on volatility in the futures markets. It is found that individual traders use momentum strategy, whereas market makers and institutional traders use contrarian strategy. Momentum strategy adopted by individual traders increases volatility whereas contrarian strategy dampens volatility. Moreover, it is found that institutional traders engage more actively in contrarian trading when individual traders cause excessive volatility. The two distinct trading groups were separately tracked prior to 2005 giving us a unique window to determine the effect of the traders that conduct momentum trading as opposed to the ones that are contrarian traders. After the reclassification, the institutional trading group exhibited weaker contrarian strategy which can be attributed to the inclusion of non-clearing firm traders. Originality/value This study documents the first empirical evidence that shows off-exchange futures trader group is not composed of only pure noise makers, but there are short-term forecasters in its group. The authors also show a unique finding that noises caused by off-exchange group is from momentum strategy that they use, whereas contrarian strategy is used by institutional trader lower volatility.

Profitability of Contrarian Strategies: Evidence From the Stock Exchange of Mauritius

The aim of this paper is to assess the profitability of contrarian strategies on the Stock exchange of Mauritius. Using data from 2001 till 2009 for all 40 listed companies on the official market, the study shows little support in favour of the contrarian effect. In particular, the losers portfolio seems to outperform the winners portfolio in one out of nine strategies. However, when considering the market return, negative excess returns are noted for all portfolios across all strategies, providing strong support for a passive portfolio management strategy and weak support for overreaction hypothesis. In addition, the Size, Price, Earnings to Price (E/P) and Book to Market (B/M) Effect has been tested. The results suggest that the average market return is greater than size-based portfolios and price-based portfolios. However, when accounting for the E/P and the B/M effect, there seems to be a strategy which can beat the market. Nevertheless, most strategies for E/P and B/M portfolios indicate insignificant excess returns. In general, the results of this paper are undoubtedly in sharp contrast with most popular studies in developed markets. However, it is observed that investors on the SEM may not possess similar characteristics to those of well-advanced markets. In particular, according to Harvey (1995), emerging market countries are sometimes relatively isolated from capital markets of other countries.
