Abstract: This study examines the cross-sectional return predictability of technical trading index and tests whether the source and the persistence of technical trading effect is the result of idiosyncratic volatility limiting arbitrage in the Chinese stock market. By eliminating common noise components in technical indicators, we propose a new technical trading index, TECHIWC, which negatively predicts future returns from short to long terms. This predictive power is not subsumed by other well-known firm characteristics. Furthermore, we find that the relationship between the TECHIWC effect and idiosyncratic volatility is significantly positive, which is consistent with idiosyncratic volatility limiting arbitrage of the TECHIWC effect. Finally, this relationship is robust to consideration of other limits of arbitrage, market states, and alternative specifications of idiosyncratic volatility.
