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.

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 recently.

EV Energy Partners

EV Energy Partners (EVEP) engages in the acquisition, development and production of oil and natural gas properties in the U.S. This stock is trading up 5.4% to $14.10 in Monday's trading session.

From a technical perspective EVEP is spiking sharply higher here right above some near-term support at $12.75 with above-average volume. This move to the upside on Monday is now quickly pushing shares of EVEP within range of triggering a near-term breakout trade. That trade will hit if EVEP manages to take out some key near-term overhead resistance levels at $14.55 to its 50-day moving average of $14.87 with high volume.

Traders should now look for long-biased trades in EVEP as long as it's trending above Monday's intraday low of $13.66 or above more key near-term support at $12.75 and then once it sustains a move or close above those breakout levels with volume that registers near or above 594,892 share. If that breakout hits soon, then EVEP will set up to re-test or possibly take out its next major overhead resistance levels at $15.66 to $16.78, or even $18.
