Screening Volatile Stocks by Turnover and Prior-Day Top List Appearance

Summary

The note proposes a short-term stock screen using three conditions: price amplitude above 1%, prior-day turnover above 60 million, and appearance on the previous day’s market top list. It presents amplitude and turnover as ways to identify active, volatile shares, while top-list inclusion is treated as a signal of market attention and possible money flows. Example snippets show how the conditions might be combined, but the document provides no backtest, measured performance, or detailed specification of the top-list data source.

The author cautions that these short-term indicators say little about company quality and that top-list appearance can reflect negative developments as well as positive attention. Suggested refinements include adding fundamental quality and value checks and applying independent research. The examples also leave implementation details unclear, including how the turnover threshold is measured and whether the listed amplitude condition is calculated consistently. The screen is best read as a candidate-selection heuristic, not as evidence of a reliable trading edge.

Key ideas

• The screen selects stocks with amplitude above 1%, prior-day turnover above 60 million, and prior-day top-list appearance.
• The note interprets volatility and turnover as signs of activity and top-list inclusion as a marker of attention.
• It warns that these short-term signals do not establish company quality and that top-list appearances may be negative.
• The examples do not report backtest results or fully specify data definitions.
• The author suggests adding fundamental analysis and value or quality filters.
