Stock Quotes in this Article: TASR, CLVS, GWPH

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 Poised for Breakouts

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.

Traders should now look for long-biased trades in TASR as long as it's trending above Friday's low of $17.50 or above its 50-day at $16.77 and then once it sustains a move or close above Friday's high of $18.88 with volume that hits near or above 1.37 million shares.
