WINDERMERE, Fla. ( Stockpickr) -- Professional traders running mutual funds and hedge funds don't just look at a stock's price moves; they also track big changes in volume activity. Often when above-average volume moves into an equity, it precedes a large spike in volatility.

Major moves in volume can signal unusual activity, such as insider buying or selling -- or buying or selling by "superinvestors."

Unusual volume can also be a major signal that hedge funds and momentum traders are piling into a stock ahead of a catalyst. These types of traders like to get in well before a large spike, so it's always a smart move to monitor unusual volume. That said, remember to combine trend and price action with unusual volume. Put them all together to help you decipher the next big trend for any stock.

With that in mind, let's take a look at several stocks rising on unusual volume today.

From a technical perspective, QCOR is ramping higher here right off its 50-day moving average of $26.88 with monster upside volume. This move has started to push shares of QCOR into breakout territory, since the stock has taken out some near-term overhead resistance at $27.91. Shares of QCOR are now quickly moving within range of triggering another major breakout trade. That trade will hit if QCOR manages to take out some near-term overhead resistance levels at $30.39 to $32.50 with high volume.

Traders should now look for long-biased trades in QCOR as long as it's trending above today's low of $27.55, and then once it sustains a move or close above those breakout levels with volume that hits near or above 1.50 million shares. If that breakout hits soon, then QCOR will set up to re-test or possibly take out its next major overhead resistance level at its 200-day moving average of $34.25. Any high-volume move above $34.25 could then send QCOR above $35 in the near future. MarketAxess
