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 Stocks Sell Before It's Too Late

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 for Breakouts

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

Hub Group

Hub Group (HUBG), an asset-light freight transportation management company, provides intermodal, truck brokerage, and logistics services in North America. This stock closed up 2.1% at $41.15 in Friday's trading session.

Friday's Volume: 504,000

Three-Month Average Volume: 293,360

Volume % Change: 79%

From a technical perspective, HUBG bounced modestly higher here right above its 50-day moving average of $40.16 with above-average volume. This move is starting to push shares of HUBG within range of triggering a major breakout trade. That trade will hit if HUBG manages to take out some near-term overhead resistance levels at $41.81 to $42.50 and then once it takes out its 52-week high of $43.09 with high volume.

Traders should now look for long-biased trades in HUBG as long as it's trending above its 50-day at $40.16 or above its 200-day at $38.66 and then once it sustains a move or close above those breakout levels with volume that's near or above 293,360 shares. If that breakout starts soon, then HUBG will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $48 to $50.

EPAM Systems

EPAM Systems (EPAM) provides software engineering solutions and technology services worldwide. This stock closed up 8.4% to $33.44 in Friday's trading session.

Friday's Volume: 1.54 million

Three-Month Average Volume: 633,179

Volume % Change: 203%

From a technical perspective, EPAM spiked sharply higher here with strong upside volume. This move is starting to push shares of EPAM within range of triggering a near-term breakout trade. That trade will hit if EPAM manages to take out Friday's high of $33.86 to its 200-day moving average of $34.64 with high volume.

Traders should now look for long-biased trades in EPAM as long as it's trending above Friday's low of $31.47 or above more near-term support just below $31 and then once it sustains a move or close above those breakout levels with volume that hits near or above 633,179 shares. If that breakout triggers soon, then EPAM will set up to re-test or possibly take out its next major overhead resistance levels at $36.58 to its 200-day moving average of $37.07. Any high-volume move above those levels will then give EPAM a chance to tag $40.

Targa Resources

Targa Resources (TRGP), through its general and limited partner interests in Targa Resources Partners LP, provides midstream natural gas and natural gas liquid services in the U.S. This stock closed up 1.4% at $104.51 in Friday's trading session.

Three-Month Average Volume: 275,517

Volume % Change: 50%

From a technical perspective, TRGP trended up modestly higher here right above some near-term support at $101.08 with above-average volume. This stock has been consolidating and trending sideways for the last few weeks, with shares moving between around $98 on the downside and $105.96 on the upside. Shares of TRGP are now quickly moving within range of triggering a big breakout trade above the upper-end of its recent sideways trading chart pattern. That trade will hit if TRGP manages to take out Friday's high of $105.12 to its 52-week high at $105.96 with high volume.

Traders should now look for long-biased trades in TRGP as long as it's trending above support at $101.08 or above its 50-day at $97.39 and then once it sustains a move or close above those breakout levels with volume that hits near or above 275,517 shares. If that breakout triggers soon, then TRGP will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $110 to $115, or even $120.

Tutor Perini

Tutor Perini (TPC) provides diversified general contracting, construction management, and design-build services to private customers and public agencies worldwide. This stock closed up 2% at $29.73 in Friday's trading session.

Friday's Volume: 465,000

Three-Month Average Volume: 267,676

Volume % Change: 80%

From a technical perspective, TPC spiked notably higher here with above-average volume. This spike higher on Friday is quickly pushing shares of TPC within range of triggering a big breakout trade.

Traders should now look for long-biased trades in TPC as long as it's trending above some near-term support levels at $28 or $27 or above its 50-day at $26.26 and then once it sustains a move or close above those breakout levels with volume that's near or above 267,676 shares. If that breakout gets underway soon, then TPC will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $35 to $40.
