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 With Big Insider Buying 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 Rocket Stocks to Buy This Week With that in mind, let's take a look at several stocks rising on unusual volume today. Crocs Crocs ( CROX) is engaged in the design, development, manufacturing, marketing and distribution of consumer products, mainly casual and athletic shoes and shoe charms, from specialty resins referred to as Croslite.

Shares of CROX closed just below those breakout levels at $13.89. Market players should now look for a continuation move higher in the short-term if CROX can manage to take out Wednesday's intraday high of $14.53 and its 200-day moving average at $14.99 with high volume. Traders should now look for long-biased trades in CROX as long as it's trending above its 50-day at $13.34 or above Wednesday's low of $12.60 and then once it sustains a move or close above $14.53 to $14.99 with volume that hits near or above 1.31 million shares.
