Stocks trading at 2x or more their 20-day average volume — unusual activity that often precedes or confirms a move.
Relative volume (RVOL) compares today's volume to a stock's own recent average. An RVOL of 2x means it is trading at twice its normal volume — a sign that something has changed: news, a breakout, or institutional activity.
This screen lists stocks with RVOL of 2.0 or higher, ranked by how extreme the volume spike is.
RVOL = today's volume ÷ the 20-session average volume. A value of 3.0 means triple the usual activity.
Stocks at 2.0x or above are listed, ranked highest-first. Volume confirms conviction behind a move — a breakout on high RVOL is more reliable than one on thin volume.
High volume is a participation signal, not direction. Pair it with the price move and trend to read what the volume means.
What is RVOL (relative volume)?
RVOL is today's traded volume divided by the stock's recent average volume (here, 20 sessions). RVOL of 2 means twice the normal volume.
Why do volume shockers matter?
A sharp jump in volume signals unusual participation — often news, a breakout, or institutional buying/selling. Moves backed by high volume tend to be more reliable.
How is the list calculated?
Strota computes each stock's 20-session average volume and divides today's volume by it. Stocks at 2x or above are listed, ranked by RVOL.
Does high volume mean the stock will rise?
No — volume shows participation, not direction. A volume shocker can be heavy selling. Read it alongside the price move. It is information, not advice.
