A Volatility and Recent-Strength Screen for A-Shares

Summary

This post describes a short-term A-share selection screen based on elevated price range, a qualifying large daily gain within the recent trading window, and a current maximum decline within a narrow band. Its stated rationale is to find volatile, recently strong stocks that may be poised for a rebound. The post also suggests adding liquidity, further technical measures, and fundamental filters such as valuation and earnings.

The document warns that the screen may favor speculative stocks, relies heavily on short-term technical signals, and can become less suitable as market conditions change. It supplies formula and sample implementation references, but leaves proposed liquidity, technical, and fundamental additions unspecified. It offers no backtest results, definition of portfolio construction or exits, transaction-cost analysis, or evidence that the rebound interpretation works. The selection rules should therefore be treated as an illustrative heuristic rather than a validated trading strategy.

Key ideas

• The screen looks for high-range stocks with a recent large daily gain and a current decline in a specified band.
• Its rationale is to identify volatile names with recent strength that may rebound.
• The post flags speculative exposure and dependence on a small set of technical conditions.
• It recommends considering liquidity, additional technical signals, and company fundamentals.
• The document reports no performance evidence and does not fully specify the suggested extra filters.
