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 Hated Earnings Stocks You Should Love 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 today.

This stock closed up 5.6% to $16.63 in Monday's trading session. Monday's Volume: 1.42 million

Volume % Change: 756% >>5 Breakout Trades Under $10 From a technical perspective, HOLI ripped higher here right off its 50-day moving average of $15.60 with monster upside volume. This move is quickly pushing shares of HOLI within range of triggering a big breakout trade. That trade will hit if HOLI manages to take out Monday's high of $16.78 and then its 52-week high at $17.66 with high volume. Traders should now look for long-biased trades in HOLI as long as it's trending above its 50-day at $15.60 and then once it sustains a move or close above those breakout levels with volume that hits near or above 149,486 shares. If that breakout hits soon, then HOLI will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $23 to $25.
