A-Share Sell-in-May Seasonality and Weekly Market Positioning Review

Summary

This May 2020 market note reviews the reported Sell-in-May calendar pattern in Chinese A-shares and states that defense and military stocks historically performed best from May through September. Given the possibility of a May pullback, its positioning view is cautious and favors keeping existing allocations, with different suggestions for heavily and lightly invested portfolios. The summary also surveys market flows, style performance, trading activity, IPO conditions, and listing activity on the STAR Market.

The document reports weekly figures for fund flows, margin balances, turnover, unlocks, and IPO-related returns, but the underlying research report is only linked by a file path and its methods are not reproduced. It offers no details on the sample period or statistical tests behind the seasonal observation, so the calendar effect and sector comparison cannot be independently assessed from this text. The stated caveats include overseas volatility, macroeconomic or policy changes, and model failure; the observations are a dated market snapshot rather than a tested current allocation rule.

Key ideas

• The note reports a historical Sell-in-May tendency in A-shares and stronger May-to-September performance for defense and military stocks.
• Its May 2020 positioning view favors caution and maintaining existing allocations amid possible near-term weakness.
• It tracks market flows, investment styles, trading activity, and IPO-related conditions alongside the seasonal discussion.
• The summary does not provide the data window or statistical tests supporting the seasonality claims.
• It flags overseas volatility, macro and policy shifts, and model failure as risks.
