China Equity Factor Review: Profitability Strength and Size Reversal

Summary

This weekly review tracks the returns and direction changes of 16 equity factors in the Chinese market during the 25th week of 2018. It reports that sales net margin had the strongest weekly performance, while valuation factors remained weak and the size factor reversed. The account also notes strength across volatility, technical, and profitability-related factors.

Ten of the 16 tracked factors changed direction from the prior week; nine moved from negative to positive, while the log of A-share free-float market capitalization turned negative. Valuation factors had been weak across the preceding four weeks, while the 24-day relative strength index and ROE had posted higher returns for nine consecutive weeks. These are reported historical observations, not a tested trading rule: the document supplies no portfolio construction details, methodology, risk adjustment, or evidence that the patterns persisted beyond the stated period.

Key ideas
