Volatility-Sorted Reversal Effects in Chinese A-Shares

Summary

This study examines how stock volatility relates to reversal and other factor returns in China’s A-share market, controlling for market capitalization and industry effects. It reports that stocks with weaker past returns tended to outperform later across reversal lookback windows from one to six months, with the strongest effect at the shortest window and weaker effects as the lookback lengthened. When reversal portfolios were divided by volatility, the middle-volatility group performed best, while the high-volatility group performed worst.

The report also evaluates profitability, value, leverage, liquidity, and residual-volatility factors. It says most tested factors had stronger results in low-volatility stocks and weaker results in high-volatility stocks, unlike reversal, for which the middle-volatility group had the best return and risk profile. These are findings from historical backtests summarized in the document; the available text does not include the full paper’s methodology, sample details, or implementation costs. The results may therefore depend on portfolio construction and market conditions and should not be treated as a forward-looking guarantee.

Key ideas

• The report finds reversal across one- to six-month lookback periods, with stronger results at shorter horizons.
• Among volatility-sorted reversal portfolios, the middle-volatility group performed best and the high-volatility group worst.
• Most tested profitability, value, leverage, liquidity, and residual-volatility factors favored lower-volatility stocks.
• The relationship between volatility and returns differs by factor category in the reported A-share backtests.
• The summary does not provide full methodology or trading-cost details, limiting conclusions about practical performance.
