A-Share Factor Portfolio Results and 2017 Style Shifts
Summary
The document groups common Chinese A-share factors into style, technical, and fundamental categories. Style factors include market, size, and value; technical factors include reversal, low turnover, and low volatility; fundamental factors cover profitability and growth. It reviews portfolios built from these factors and reports that each category produced positive returns over 2010–2017, with size leading, technical factors next, followed by market, then fundamentals and value.
The 2017 results differed from the longer-run pattern: size reversed sharply and reversal had a notable drawdown in the first half, while low turnover, low volatility, profitability, and growth remained strong. Six of the eight portfolios were positive for the year. The outlook favored technical and fundamental factors over style factors, whose recent results appeared less reliable. These are historical observations and a dated forecast, not evidence that the returns will persist; the document explicitly warns that factor performance can fail in the future.
