Interpretation guide
How to use trading value spikes
The Trading Value Spikes radar finds stocks where substantially more money is changing hands than usual. Turnover often appears before a trend becomes obvious, so this screen helps confirm whether a new catalyst is receiving real market attention.
Selection rules
The screen compares current trading value with the recent 20-session average and ranks names with the largest multiples. Minimum turnover filters reduce noise from very small stocks.
- Turnover spike shows how many times current trading value exceeds the recent average.
- A liquidity floor keeps the list focused on names that can be traded realistically.
- Market cap helps separate small-cap bursts from institutional large-cap flows.
How to interpret it
A turnover spike is not automatically bullish. It can represent accumulation or distribution, so price location and the close matter. A strong close with high turnover suggests demand; a weak close with high turnover can suggest supply.
- Above 1.5x is a meaningful increase in attention.
- Above 2.0x deserves a check for news, earnings, policy, or flow events.
- High turnover with weak price action can signal heavy overhead supply.
How to respond
Fast-moving turnover names need a plan before entry. Confirm whether the stock closes well, whether volume persists the next day, and whether the move connects to a breakout or trend reversal.
- Strong close plus turnover spike can become a pullback watchlist candidate.
- Weak price action should trigger news and resistance checks before chasing.
- On weak breadth days, treat turnover spikes as more likely to be short-term thematic trades.
