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 Rocket Stocks to Buy for Earnings Season

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 Big Breakouts

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

Zoltek

From a technical perspective, ZOLT soared higher here right above its 50-day moving average at $13.23 with above-average volume. This stock also entered breakout territory, since the stock took out some near-term overhead resistance at $14.43. This breakout is significantly, since shares of ZOLT had been trending range bound for four months, with shares moving between $12 on the downside and just over $14 on the upside.

Traders should now look for long-biased trades in ZOLT as long as it's trending above $14.43 or $14 and then once it sustains a move or close above Monday's high at $15.50 with volume that hits near or above 253,763 shares. If we get that move soon, then ZOLT will set up to enter new 52-week-high and three-year-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $20 to $22.

This move is quickly pushing shares of KLIC within range of triggering a near-term breakout trade. That trade will hit if KLIC manages to take out some near-term overhead resistance levels at $12 to $12.56 with high volume.

Traders should now look for long-biased trades in KLIC as long as it's trending above its 50-day at $11.48 or its 200-day at $11.19 and then once it sustains a move or close above those breakout levels with volume that hits near or above 540,702 shares. If that breakout triggers soon, then KLIC will set up to re-test or possibly take out its next major overhead resistance levels at its 52-week high of $12.95 to its 3-year high at $13.69.

Keep in mind that KLIC is set to report earnings on July 30 before the market open. Look to play this breakout ahead of the quarter and then after as long as the stock continues to uptrend once earnings are out.
