Who Are the Market Beaters: Lucky Investors, Insiders or Who Else?

Öz:
Conditions of beating the market is always top of the interests of investors throughout the history. In this study we aim to find who beats the market using a special trade and portfolio data from a stock exchange namely Borsa İstanbul. Instead of market data, investor based data used in this paper provides us to make stronger analyses. We initially find that 87% of individual and 92% of institutional investors get returns in a random way. Then the rest of investors are investigated to determine who consistently beats the market and gets abnormal returns. And we mainly find that the market beating gets longer with increasing portfolio size and diversification, while it gets shorter with increasing turnover. Additionally, longer beating length means higher shares of women, old adults, funds and foreigner. Furthermore, we analyze the return performance of investors in our study and show that the picture becomes reversed compared to beating length criteria. Finally, the insiders are compared with other investors to understand whether the market is efficient in the strong form or not. And the findings indicate that the insiders cannot be specifically differentiated from other investors. Therefore, we end up with the evidence that there is strong form efficiency in Borsa İstanbul.

  • We define market beaters (beatens) as the group of investors who over-perform (under-perform) the market. That is, investors who have positive (negative) adjusted return are called as market beaters (beatens). Although the term of beater is generally used in the literature, the terms such as loser, underperformer, fool are preferred instead of beatens. In this study, the term of beaten has been intentionally chosen due to its simplicity and addition of originality.
  • We mean by “run” is the sequence of successive adjusted returns with same sign. Suppose we have following Daily adjusted returns: 0.02, 0.05, -0.01, -0.02, 0.01, -0.02, -0.03, -0.01, 0.03. Signs of these returns generate the sequence: + + - - + - - - + which contains four positive and two negative runs.
  • We define an investor as an inefficient if his/her result of runs test is not significant in 5% significance level, i.e., if |z|>1.96.
  • It is a fact that formal normality tests always reject on the huge sample sizes we work with today. It's even easy to prove that when n gets large, even the smallest deviation from perfect normality will lead to a significant result. As n gets larger, skewness and kurtosis become less important - and directed tests are likely to detect if these quantities deviate from 0 even by a small amount.
  • Since we could not find any significant change, we prefer to present the results by separating the investors in just two districts: Marmara and Other.
  • During the period of our study Individual investors that capture 21% of the market capitalization. Also, 84% of largest shareholders are institutional investors. If we consider only stocks from BİST100 Index, then this ratio increases to more than 90%.
