How these are measured
- Turnover
- — dollar volume over market cap; how hard this name is traded relative to its size.
- Vs prior 20 sessions
- — above 1 means heavier trading than in the 20 sessions before it.
- Share of market volume
- — of the 250 names tracked in United States, not the whole market.
- Volatility
- — from daily returns over the held history. Indicative, not a risk model.
- Market cap
- — the latest session's close × shares outstanding, in USD. Each day in the history has its own, from that day's close; the share count is refreshed monthly.
