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.>>5 Hated Earnings Stocks You Should Love 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. >>5 Stocks Poised to Break Out With that in mind, let's take a look at several stocks rising on unusual volume today. SunPower SunPower ( SPWR) is a vertically integrated solar products and services company that designs, manufactures and delivers high-performance solar electric systems worldwide for residential, commercial, and utility-scale power plant customers. This stock closed up 10.6% at $34.16 in Monday's trading session. Monday's Volume: 5.46 million
Three-Month Average Volume: 3.41 million
Volume % Change: 165% >>5 Rocket Stocks to Buy in November From a technical perspective, SPWR skyrocketed higher here right off $32 with strong upside volume. This stock recently pulled back right to its 50-day moving average with bearish downside volume flows. Following that pullback, shares of SPWR have now rebounded sharply off its 50-day, and it's quickly moving within range of triggering a big breakout trade. That trade will hit if SPWR manages to take out Monday's high of $34.47 to its 52-week high at $35.39 with high volume. Traders should now look for long-biased trades in SPWR as long as it's trending above Monday's low of $31.90 and then once it sustains a move or close above those breakout levels with volume that hits near or above 3.41 million shares. If that breakout hits soon, then SPWR 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.
