Stock Screening with Buying Pressure and Trade Imbalance

Summary

This post proposes a stock screen combining a reported increase in daily position accumulation above five percent with an external-to-internal trading-volume ratio above 1.3. It also references 2021 as a time filter, describing it as a way to exclude recently listed stocks. The accompanying explanation interprets the accumulation measure as a sign of capital inflow and the volume ratio as an indication of market attention, then suggests using both conditions together rather than relying on either alone.

The post warns that these signals can be unrelated and may reflect excessive optimism or attention that leaves a stock overvalued. It recommends monitoring market conditions and adjusting the strategy, but provides no definitions of the data fields, universe details, entry or exit rules, backtest, transaction costs, or performance evidence. The screening logic is therefore an informal hypothesis, not a validated strategy; the role and date scope of the year filter are also unclear in the text.

Key ideas

• The proposed screen combines daily position accumulation above five percent with an external-to-internal volume ratio above 1.3.
• The post treats position accumulation as a possible indicator of capital inflow and the volume ratio as a proxy for attention.
• It warns that these conditions may not be related and that strong inflows or attention can accompany overvaluation.
• The document provides no backtest, cost analysis, full trading rules, or validation of the proposed signals.
