Screening for High Amplitude, Recent Leaderboard Presence, and a Lower Low

Summary

This Chinese stock-selection post describes a short-term screen using three conditions: price amplitude greater than 1, appearance on the previous day’s market leaderboard, and today’s low below yesterday’s low. Its rationale treats high amplitude as evidence of active price movement, leaderboard presence as a sign of attention or strong sentiment, and the lower low as a pullback that might precede a rebound. The article gives example indicator-formula and Python-style logic for combining the conditions, but it reports no historical test, benchmark, or evidence that rebounds follow these signals.

The post warns that the screen can select volatile stocks, that leaderboard data alone may not represent the broader situation, and that fundamental factors are omitted. It suggests adding technical indicators, financial measures, market and sector context, capital-flow information, or industry constraints. The code examples also merit implementation checks: the amplitude example uses prior-bar values, while the prose describes today’s amplitude, and the Python snippet compares a series of lows against a single prior low. These differences can affect which stocks qualify.

Key ideas

• The screen combines amplitude above 1, prior-day leaderboard appearance, and a current low below the previous low.
• The proposed interpretation is that attention and volatility coincide with a pullback that could rebound.
• The post supplies example screening logic but no performance evidence or validation results.
• The strategy can involve substantial volatility and does not account for company fundamentals.
• The code examples differ from the prose in timing and comparison details, which should be checked before use.
