Theories predict that, due to investor under-diversification, idiosyncratic risk is positively priced in expected stock returns. Empirical studies based on various methodologies yield mixed evidence. This study circumvents the debate on methodological issues and traces the pricing of idiosyncratic risk to its economic source – investor under-diversification. Assuming that institutional investors tend to hold more diversified portfolios and thus care little about idiosyncratic risk relative to individual investors, we find that the positive relation between idiosyncratic risk and stock returns is significantly stronger (weaker) in stocks that are held and traded more by individual (institutional) investors. In addition, the pricing …


Reference Point Adaptation And Disposition Effect: Evidence From Institutional Trading, Chiraphol N. Chiyachantana, Zongfei Yang Jul 2010

Reference Point Adaptation And Disposition Effect: Evidence From Institutional Trading, Chiraphol N. Chiyachantana, Zongfei Yang

Using a large proprietary database of institutional trades, we investigate whether, and to what extent, the dynamic adaptation of reference point translates into variations in the disposition effect, and establish three key results. First, the propensity to realize losses declines sharply with the magnitude of prior losses due to insufficient adaptation of reference point. Second, recent adverse information accelerates investors’ adaptation to price depreciation and increases investors’ willingness to realize losses. Finally, a priori of losing money in highly speculative investments decreases investors’ aversion to realize losses. Collectively, the findings suggest that both prior outcomes and recent expectations contribute to …
