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. Many times when above average volume moves into 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.

Endo Health Solutions

From a technical perspective, ENDP is moving higher here back above its 200-day moving average of $33.68 on above average volume. At last check, ENDP traded a bit above its 50-day moving average of $35.44, after the stock hit an intraday high of $35.60.

Traders should now look for long-biased trades if ENDP can trigger a near-term breakout trade. That trade will hit once ENDP takes out its 50-day at $35.60 and then some near-term overheard resistance at $36.30 with high volume. Look for a sustained move or close above those levels with volume that’s near or above 1.3 million shares. If we get that action soon, then look for ENDP to make a run at its March high of $39.29.

As of the most recently reported quarter, Endo is one of the top holdings of Lee Ainslie's Maverick Capital.

That trade will hit once FMCN can manage take out some near-term overhead resistance at $22.64, and then its 200-day at $24.02 and its 50-day at $24.11 with high-volume.

Traders should look for long-biased trades if FMCN can take out all of those levels with volume that’s near or above 2.2 million shares. If we get that action soon, then FMCN can easily hit $26 to $28 in the near future.

Traders should now look for long-biased trades if SPRD can sustain a move or close above $18.32 to $18.55 with volume that’s near or above 1,276,010 shares. If we get that action today or soon, then look for SPRD to continue its uptrend toward its next significant overhead resistance levels at $21.16 to $21.37, or possibly back toward $23.05.

Today’s Volume: 2.1 million

Volume % Change: 394%

From a technical perspective, ROSG is spiking notably higher here on monster volume. At last check, ROSG has hit an intraday high of $16.65 and volume is well above its three-month average action of 618,708 shares.

Traders should only look for long-biased trades if ROSG can manage to take out Friday’s high of $17.50 with high volume. Look for a sustained move or close over $17.50 with volume that’s near or above 618,708 shares. On the flipside, I would look for short-biased traders if ROSG fails to take out $17.50, and then moves below some major near-term support at $12.71 with high volume.

Allot Communications

Allot Communications (ALLT) is a provider of intelligent IP service optimization, monetization and personalization solutions for mobile, fixed and wireless broadband service providers and enterprises. This stock is trading up 4.1% at $24.89 in recent trading.

This move has briefly pushed ALLT into breakout territory since the stock took out some near-term overhead resistance at $24.62. At last check, ALLT has moved back below that breakout level with shares now trading at $24.89.

Traders should now look for long-biased trades if ALLT can manage to trigger a breakout above $24.89 and then above its 52-week high of $26.97 on high volume. Look for a sustained move or close above those levels with volume that’s near or above 470,180 shares. If we get that action soon, look for ALLT to tag $30 in the near future.

On the flipside, I would avoid ALLT if it moves back below its 50-day moving average of $23.49 with heavy volume.

Cirrus Logic

Cirrus Logic (CRUS) develops high-precision, analog and mixed-signal integrated circuits (ICs) for a range of audio and energy markets. This stock is trading up 4.8% at $28.79 in recent trading.

From a technical perspective, CRUS is spiking sharply higher here on above average volume. This move has pushed CRUS into breakout territory, since the stock has taken out some near-term overhead resistance at $28.25 with strong volume.

Traders should now look for long-biased trades as long as CRUS is trending above $28.25 to today’s high of $29.30 with strong upside volume flows. I would consider any upside volume day that registers near or above 2,433,420 as bullish. If we continue to see CRUS trending above $28.25 to $29.30 with strong volume, then this stock should head north of $30 in the near future.

Average Volume: 610,758

Volume % Change: 52%

From a technical perspective, SYNC has started to flirt with a major breakout trade today, since the stock has briefly moved above some near-term overhead resistance at $11.89 with decent volume. At last check, SYNC has hit an intraday high of $12.50, but it has since pulled back to just under $12.

Traders should continue to look for long-biased trades as long as SYNC is trending above $11.89 and today’s high of $12.50 with strong upside volume flows. I would consider any upside volume day that’s near or above 610,758 shares as bullish. If we continue to see SYNC trending above those levels, then this stock has a great chance of re-testing its all-time high of $13.60, and potentially trending even higher.
