Infinity volume insights

since 27 March 2025

Every session our rules flagged for this company since 27 March 2025: 12. Those marked “In the feed” were published in the daily feed at the time; the rest are computed with the rules in use now. The feed shows a few a day across every market, so most never appear there. We began tracking this company on 28 September 2026; findings before then are marked “Before we tracked it”: it traded that way, and we were not yet watching.

Price and dollar volume

Bars coloured by direction

The last three months, one point a week (the week's last close and its total dollar volume).

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 110 names tracked in Japan, 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.
