DELAFIELD, Wis. (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.
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.>>5 Stocks Ready to Break Out With that in mind, let's take a look at several stocks rising on unusual volume recently. VeriFone Systems VeriFone Systems (PAY - Get Report) designs, markets and services electronic payment solutions at the point of sale worldwide. This stock closed up 8.7% to $34.94 in Monday's trading session. Monday's Volume: 4.60 million
Three-Month Average Volume: 1.57 million
Volume % Change: 162% From a technical perspective, PAY gapped up sharply higher here back above its 50-day moving average of $32.51 with strong upside volume flows. This move pushed shares of PAY into breakout territory, since the stock took out some near-term overhead resistance levels at $34.58 to $34.78. Shares of PAY are now quickly moving within range of triggering an even bigger breakout trade. That trade will hit if PAY manages to take out its 52-week high of $35.11 to some past resistance at $36.13 with high volume. Traders should now look for long-biased trades in PAY as long as it's trending above Monday's low of $33.34 or above its 50-day at $32.61 and then once it sustains a move or close above those breakout levels with volume that hits near or above 1.57 million shares. If that breakout triggers soon, then PAY will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $40 to $45.
