Screening Stocks by Amplitude, Five-Day Trend, and Low Price

Summary

This Chinese-language post presents an equity screen requiring daily amplitude above a threshold, the stock price above its five-day moving average, and a price below 12. It interprets higher amplitude as greater opportunity, the moving-average condition as an upward trend, and the low price as a possible rebound setup. The accompanying examples describe implementing the filters with market data and stock-screening formulas.

The post cautions that a low share price does not establish undervaluation and may reflect weak company performance. It also identifies impulsive buying and selling as operational risks. The proposed refinement is to consider company fundamentals, historical performance, industry and market conditions, and potentially analytical models. No backtest, performance data, or evidence that the screen predicts returns is provided, so the rationale remains a set of hypotheses rather than a validated strategy.

Key ideas

• The screen combines daily amplitude, price relative to a five-day moving average, and a low share-price cutoff.
• The author interprets the moving-average filter as an indication of an upward trend.
• A low nominal share price does not by itself show that a stock is undervalued.
• The post recommends combining technical filters with company, industry, and market analysis.
• No performance test is provided to establish the screen's effectiveness.
