WINDERMERE, Fla. (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 today.

>>5 Stocks Ready to BreakOut

Elizabeth Arden (RDEN) is a beauty products company with a portfolio of prestige fragrance, skin care and cosmetics brands. This stock closed up 1% at $40.89 on Wednesday.

Wednesday's Volume: 543,000

Average Volume: 280,770

Volume % Change: 72%

From a technical perspective, RDEN bounced modestly higher here and briefly moved back above its 50-day moving average of $40.98 with above-average volume. Shares of RDEN hit an intraday high of $41.88, but the stock pulled back and closed just below its 50-day. This move is quickly pushing shares of RDEN within range of triggering a major breakout trade. That trade will hit if RDEN manages to take out its 50-day at $40.98 and then once it clears more past resistance at $42 with high volume.

Traders should now look for long-biased trades in RDEN as long as it’s trending above its 50-day at $40.98 or above Wednesday’s low of $40.02 and then once it sustains a move or close above those breakout levels with volume that hits near or above 280,770 shares. If that breakout triggers soon, then RDEN will set up to re-fill some of its previous gap down zone from late January that started near $48. Some potential targets if RDEN gets into that gap with volume are its 200-day moving average at $43.24, or $44 to $45.
