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.

Clearwater Paper

Clearwater Paper (CLW) - Get Report manufactures and sells private label tissue and paperboard products in the U.S. and internationally. This stock is trading up 1.4% to $60.89 in Friday's trading session.

Friday's Volume: 228,000
Three-Month Average Volume: 147,161
Volume % Change: 294%

From a technical perspective, CLW is trending modestly higher here right above its new 52-week low of $58.43 with above-average volume. This stock gapped down sharply in Thursday's trading session from $74 to that new 52-week low of $58.43 with heavy downside volume flows. That move has now pushed shares of CLW into oversold territory, since its current relative strength index reading is 27. Oversold can always get more oversold, but shares of CLW are starting to rebound of that recent low with volume. Traders should now look for a continuation move to the upside in the short-term if CLW manages to clear Friday's intraday high of $61.77 with high volume.

Traders should now look for long-biased trades in CLW as long as it's trending above Friday's intraday low of $60.44 or above its new 52-week low of $58.43 and then once it sustains a move or close above Friday's intraday high of $61.77 with volume that hits near or above 147,161 shares. If that move gets started soon, then some possible upside targets are $64 to its 200-day moving average of $66.18.

Endurance International Group

Three-Month Average Volume: 463,385
Volume % Change: 179%

From a technical perspective, EIGI is ripping sharply higher here back above its 50-day moving average of $17.25 with above-average volume. This sharp spike to the upside on Friday is now quickly pushing shares of EIGI within range of triggering a major breakout trade above some key near-term overhead resistance levels. That trade will hit if EIGI manages to take out some key near-term overhead resistance levels at $18.26 to its all-time high of $19.09 with high volume.

Traders should now look for long-biased trades in EIGI as long as it's trending above Friday's intraday low of $16.69 or above more near-term support at $15.92 and then once it sustains a move or close above those breakout levels with volume that registers near or above 463,385 shares. If that breakout materializes soon, then EIGI will set up to enter new all-time-high territory above $19.09, which is bullish technical price action. Some possible upside targets off that breakout are $23 to $25.
