Unusual volume stocks today – up on high relative vol (RVol) | NYSE, NASDAQ and AMEX

Traders watch for unusual volume stocks because they are often accompanied by large price movements. Increased volume flows are correlated with volatility. A heightened volume indicates something is going on today and that the stock is “in play”. A stock moving up on unusually high volume typically signifies an outsized demand to own the stock.

Relative volume is a ratio called RVol. We compare current cumulative volume to average cumulative volume for the same time of day. High relative volume is also referred to as a “volume spike”.

If RVol is 5, it means that the stock has generated 5 times its normal volume, for this time of the day.

We use the 5-day average daily volume as the measuring baseline.
