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 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.

Let's take a look at a

number of stocks rising on unusual volume today

. They are all recording volume in midday trading that is already at least 50% above their average trading volume for a full day.

From a technical standpoint, CALL is bouncing big off of its 50-day

moving average

of $11.63 on big volume. Traders should now watch for a sustained move and close either near or above today's high of $13.23.

If we close near today's highs, then look for CALL to break out above some near-term

overhead resistance

at $13.60 to $13.68. A

high-volume move

and close over those levels should set this stock up to trend back toward its next significant overhead resistance levels at $16.95 in the near future.

technical standpoint

, ADES is

trigging a major breakout

today now that the stock has cleared some past overhead resistance at $20.97 on heavy volume. As long as ADES can hold above $20.97 at the close today, and finish near the daily highs, then this stock should set up to trend back toward its March high of $24.92.

Today's Volume: 567,000

Average Volume: 464,602

Volume % Change: 188%

This stock is moving nicely to the upside today after Oppenheimer said that the recent share weakness was related to short positions initiated by general partners at Benchmark Capital as a hedge. Oppenheimer reiterated an outperform rating on the stock.

From a technical standpoint, shares of ZIP are bouncing big off of extremely oversold levels since the stock just dropped from its November high of $21.41 to a recent low of $12.04. The next buy point on ZIP will trigger once the stock clears $16 on high-volume.

Traders should look for a sustained move over $16 on volume that's near or above 464,602 shares. If we get that move, look to add to any long positions once ZIP takes out its 50-day at $16.94 with heavy volume.

If we get a high-volume move and close above those levels, then look for MAPP to challenge its October high of $16.19 in the near future.

Volume % Change: 754%

>>5 Stocks Under $10 Set to Soar

From a technical standpoint, SSRX is bouncing big off its

52-week low

of $9.50 on monster volume. This is clearly an oversold snapback rally since shares of SSRX just dropped from its December high of $13.41.

Traders should now look for the next buy point to trigger if SSRX can sustain a move and close above today's high of $10.16 with volume. If we see that action, then look for SSRX to make a run at $11.48 (its 50-day) in the near future.

Today's Volume: 2,977,000

Average Volume: 2,627,890

Volume % Change: 115%

This stock is soaring today after Canaccord said it would be aggressive buyers of INHX due to the overreaction in shares following



PSI-938 clinical developments. Canaccord rated the stock a buy with a $22 price target.

From a technical standpoint, INHX is starting to trend back above its gap down day high of $10.45 on heavy volume today. Traders should now watch for a sustained high-volume move and close above $10.45 to signal that this stock wants to continue to fill the gap back towards $14.

Keep in mind that this stock just bounced big off its pre-market low of near $5 from that huge gap down day last week. That's an over 100% run now for INHX, so profit-taking could easily hit this stock at any moment.

Spectrum Pharmaceuticals

Spectrum Pharmaceuticals

(SPPI) - Get Spectrum Pharmaceuticals, Inc. Report

is a commercial stage biopharmaceutical company, engaged in developing and commercializing therapies with a focus primarily in the areas of hematology-oncology and urology. This stock is trading up 4.2% at $15.12 in recent trading

Today's Volume: 1.1 million

Average Volume: 1.3 million

Volume % Change: 65%

From a technical standpoint, SPPI is starting to

trigger a major breakout today

now that the stock is flirting with some near-term overhead resistance at $15.09 on solid volume. Market players should now watch for sustained high-volume move and close over $15.09 to signal that this stock wants to move higher in the near future.

If we get that action, I would keep a long bias on this stock and look to play it for more upside as long as we stay above $15.09, within a few percentage points.

Shares of NICE recently had a huge volume down day of 716,500 shares. That big volume down day might have marked a near-term bottom in the stock, again, as long as $31.26 holds.
