Highest Volume Since IPO

A stock’s busiest day ever is rarely quiet news. Record volume usually marks a catalyst: a breakout, a gap on earnings, a takeover bid or a squeeze, and it tells you the market suddenly cares about a name it was ignoring. This scan lists stocks whose daily volume in the last 10 calendar days is the highest since they listed (HVIPO). Today counts as soon as the volume traded so far passes the record, so a name can appear intraday. A stock needs 20 sessions of history first, so a new listing does not qualify every day. For a company that listed before the stored history begins, around 2003, the record is the highest volume in that history. Names must average at least $2 million a day in dollar volume over their last 20 sessions, and a stock is skipped on the day of a stock split. The list changes at midnight ET. Results are sorted by market cap, largest first. Record volume says how much traded, not which way price will go, so read the chart before acting.
