Combining Recent Limit-Ups with Buying Activity in a Stock Screen
Summary
This proposed stock screen combines a measure of current buying activity with recent limit-up occurrences. Its stated conditions are a buying-share measure above five percent and more than two limit-up days within ten days; it also refers to a listing-age condition, though the threshold is left unspecified. The article explains the buying measure as an indication of relative buying interest and treats repeated limit-ups as a sign of strong short-term expectations. It later proposes adding valuation and trading-volume filters, but these differ from the initial screen and are not clearly reconciled with it.
No backtest, return series, or other empirical support is provided. The article cautions that recent price action does not assess company quality or longer-term prospects, and that sentiment shifts or adverse policy changes may trigger losses. It suggests adding valuation and technical indicators, but does not test whether those additions improve selection or timing. The partial code is a reference rather than a complete implementation, so the conditions and data definitions would need clarification before replication.
Key ideas
- The proposed screen combines a buying-activity measure above five percent with more than two limit-up days in a ten-day period.
- The listing-age condition is mentioned without a clear threshold.
- The article interprets repeated limit-ups and buying activity as signs of short-term demand, but reports no performance evidence.
- It warns that the screen omits company fundamentals and is vulnerable to changes in sentiment or policy.
- Suggested valuation and technical filters are not validated, and the code reference is incomplete.
