Screening for Volatile Stocks with Recent Top-List Activity and Three-Day Declines

Summary

This Chinese equity screening idea combines three conditions: daily amplitude above 1 percent, appearance on the prior day’s top trading-activity list, and a decline over the preceding three sessions. The rationale is that a large range signals short-term volatility, top-list activity may indicate unusual fund flows, and a run of falling prices could leave a stock vulnerable to a rebound. The note supplies formula-style and Python examples for intersecting the three candidate sets.

The proposal is a short-term reversal hypothesis, not a tested strategy. No historical results, execution assumptions, or risk-adjusted measures are provided. The code’s three-session price-difference check identifies a net decline across the interval, which does not necessarily establish that each of the three sessions fell. The author also warns about market-wide reversals and the omission of fundamental analysis, and suggests adding volume or relative-strength measures and examining industry groups. These additions are suggestions rather than evaluated improvements.

Key ideas

• The screen combines amplitude above 1 percent, prior-day top-list presence, and a net price decline across three sessions.
• The proposed rationale is that volatile, actively traded stocks after a decline may rebound.
• The examples show how to intersect candidates that pass each condition.
• A net three-session decline does not prove that every session was down.
• The note provides no backtest and flags market risk and missing fundamental information.
