Idiosyncratic tail risk and expected stock returns: Evidence from the Chinese stock markets

We estimate idiosyncratic tail risk according to the extreme value theory. Both portfolio analyses and cross-sectional regressions suggest a significant negative relationship between the idiosyncratic tail risk and the expected returns in Chinese stock markets after controlling for other risk measures including size, book-to-market ratio, beta, momentum, short-term reversals, liquidity, idiosyncratic volatility, downside beta, co-skewness, co-kurtosis, idiosyncratic skewness, idiosyncratic kurtosis, value at risk and maximum daily returns. Turnover explains the negative effect of the idiosyncratic tail risk in Chinese stock markets where individual investors dominate the markets and short sales are constrained.
