Abstract

This study has two research objectives: (1) to find evidence whether investment decisions (allocation of funds in each asset in a portfolio) of Indonesian investors in the short investment horizon diverge with their investment decisions in the long investment horizon, and (2) to examine the belief of Indonesian investors in the mean reversion. This study analyzes the investment horizon from a behavioral point of view by examining the influence of investment horizon on investment decision and mean reversion in Indonesia. We employed the students of Master of Science, Master of Management, and Doctorate Programs at the Faculty of Economics and Business, Universitas Gadjah Mada, Indonesia as the sample in this research. Of the 217 questionnaires delivered, 172 questionnaires were completely filled and utilized in this study.The main findings of this study are as follows: (1) it is significantly proved that Indonesian investors are inclined to assume higher portfolio risk in the longer investment horizon than that in the shorter investment horizon; (2) it is very interesting to see that on average, the investors are inclined to increase their allocation in the risk-free asset in the longer investment horizon although the difference between the risk-free asset holding in the short investment horizon and that in the long investment horizon is not significant; (3) the framing effect significantly influences the investment decisions, both in short investment horizon and in long investment horizon; (4) there is a tendency for the respondents to show a willingness to assume higher portfolio risk when they received the questionnaires that provided the historical five-year returns on the first page; (5) investors predict an asset gaining 50 percent in the first year to continuously gain in the next four years while expecting an asset losing 25 percent in the first year to continuously loss in the next four years.

Abstract

On July 3, 2000, the Jakarta Stock Exchange (JSX) reduced its tick size from Rp25.00 to Rp5.00. This study examines the impact of the tick size reduction on the JSX bid-ask spread, market depth, and trading activity. Using daily data, this study finds that the rupiah spread, percentage spread, and depth decreased significantly. All of these findings are not surprising since they are consistent with previous studies conducted in several different markets.In contrast to previous studies, this study finds that the key variable in determining the difference in performance of JSX stocks following the tick size reduction is the price of the stock. Specifically, all the trading activity measures e.g. in the number of trades, share volume, and rupiah volume, increased for low-priced stocks. Conversely, trading activity decreased for high-priced stocks. The possible explanation is that absolute tick size Rp5.00 is too small in economic terms for JSX high-priced stocks, so those decrease the investors’ willingness to trade.

Abstract

This study attempts to investigate the issue of the existence of institutional herding in the stock market. The existence is detected in the intraday trade data from the Indonesia Stock Exchange (IDX) during up, down, and stable market condition over the period 2003-2005. By using the model of Lakonishok et al. (1992), it is found that the intensity of the existence of institutional herding at the IDX, on average, is 8.4 percent. Institutional investors do not seem to lead their transactions ina certain characteristic of stock. Most of them follow positive-feedback trading strategy while others follow negative-feedback trading strategy. This study also found that the existence of herd behavior at the IDX did not destabilize the market price in a subsequent period.

Abstract

This study examines the dividend life-cycle hypothesis and the propensity of non-financial firms listed on the Indonesia Stock Exchange (IDX) to pay dividends, in light of a recent idea by the IDX to regulate dividend payments. Using several proxies of the life cycle, the results consistently show that Indonesian listed firms follow the dividend life-cycle hypothesis. Our results recommend that if the authority insists on regulating dividend payments, the regulation should take into account the firms’ life cycles. Firms should only be required to pay dividends when they reach a certain stage and/or meet defined characteristics, according to their stage or characteristics.

Abstract

The study was organized into two major concerns: first, identifying the gains from international diversification in emerging stock markets from the Philippine and the Indonesian perspectives and determining which perspective yields the greater gains; and second, determining how many securities must be included to obtain an optimal investment portfolio from the Philippine and Indonesia perspectives.The empirical results indicate that there are gains from international diversification, both from the Philippine and Indonesian perspectives, in two to eight emerging stock markets. Generally the gains are greater from the Indonesian perspective than the Philippine perspective in all countrycombinations.Further, this study found that the number of stocks needed to form an optimum domestic investment portfolio was bigger for the Indonesian investor‘s perspective (at 15 stocks) than for the Filipino investor (14).
