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.

>>5 Stocks Poised for Breakouts

Republic Airway

Republic Airway (RJET) offers scheduled passenger services through its wholly owned operating air carrier subsidiaries: Chautauqua Airlines, Shuttle America Corporation, Republic Airline and Frontier Airlines. This stock is trading up 5% at $10.46 in recent trading.

Today’s Volume: 1.19 million

Average Volume: 580,110

Volume % Change: 178%

From a technical perspective, RJET is ripping higher here right above some near-term support at $9 with heavy upside volume. This move has started to push shares of RJET into breakout territory and new 52-week-high territory, since the stock has cleared some near-term overhead resistance at $9.94.

Traders should now look for long-biased trades in RJET as long as it’s trending above $9.94 and then once it sustains a move or close above its new 52-week high of $10.50 with volume that hits near or above 580,110 shares. If that RJET can maintain that trend, then this stock could possibly hit $12 to $13 in the near future.

Stratasys

Stratasys (SSYS) is a manufacturer of three-dimensional printers and high-performance rapid prototyping systems for the office-based RP and direct digital manufacturing markets. This stock is trading up 6.9% at $68.17 in recent trading.

Today’s Volume: 2.98 million

Average Volume: 835,052

Volume % Change: 490%

Shares of SSYS are soaring higher here after the company posted a loss for its fourth quarter but beat Wall Street earnings estimates and issued a full-year sales forecast that ranged higher than analysts were expecting.

From a technical perspective, SSYS is gapping sharply higher here back above its 200-day moving average of $64.21 with heavy upside volume. This gap up has at least briefly stopped the stock’s downtrend over the last month, which took shares of SSYS lower from $84.10 to $60.20. This move is quickly pushing shares of SSYS within range of triggering a near-term breakout trade. That trade will hit if SSYS takes out its intraday high of $72.69 with high volume.

Traders should now look for long-biased trades in SSYS as long as it’s trending above today’s low of $67.53, and then once it sustains a move or close above $72.69 with volume that hits near or above 835,052 shares. If that breakout hits soon, then SSYS will set up to re-test or possibly take out its 50-day moving average of $78.08.

OSI Systems

OSI Systems (OSIS) is engaged in the design and manufacture of electronic systems and components for critical applications. This stock is trading up 3.7% at $59.73 in recent trading.

Today’s Volume: 542,000

Average Volume: 242,082

Volume % Change: 181%

From a technical perspective, OSIS is ripping higher here and breaking out above some near-term overhead resistance at $57.87 with above-average volume. This move has also pushed shares of OSIS right into its 50-day moving average of $61.26. At last check, OSIS has hit an intraday high of $61.35 with volume that’s well above its three-month average action of 242,082 shares. Shares of OSIS are now starting to move within range of triggering a near-term breakout trade. That trade will hit if OSIS manages to take out its 50-day at $61.26 with high volume.

Traders should now look for long-biased trades in OSIS as long as it’s trending above $57.87 and then once it sustains a move or close above its 50-day at $61.26 and at $61.35 with volume that hits near or above 242,082 shares. If that breakout triggers soon, then OSIS will set up to re-test or possibly take out its gap down day high of $64.19. Any high-volume move above $64.19 will then give OSIS a chance to re-fill some of its gap down zone from January that started at $72.

Veolia Entertainment

Veolia Entertainment (VE) is a provider of environmental management services, which include water and wastewater services, waste management services, energy services and transportation services. This stock is trading up 5.5% at $13.18 in recent trading.

Today’s Volume: 370,000

Average Volume: 260,308

Volume % Change: 100%

From a technical perspective, VE is trending higher here right above its 50-day moving average of $12.27 with above-average volume. This move has started to push shares of VE into breakout territory, since the stock has taken out some near-term overhead resistance at $13.17. At last check, VE has hit an intraday high of $13.39 and volume is well above its three-month average action of 260,308 shares. This move is also pushing shares of VE within range of triggering another major breakout trade. That trade will hit if VE clears some past overhead resistance at $13.76 with high volume.

Traders should now look for long-biased trades in VE as long as it’s trending above today’s low of $13.10, and then once it sustains a move or close above $13.17 to $13.76 with volume that hits near or above 260,308 shares.
