 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.

Allscripts Healthcare Solutions

Allscripts Healthcare Solutions (MDRX) is a provider of clinical, financial, connectivity and information solutions and related professional services to hospitals, physicians and post-acute organizations. This stock is trading up 4.5% at $10.77 in recent trading.

Today’s Volume: 13.7 million

From a technical perspective, MDRX is bouncing sharply higher here after the stock just recently plunged from $16 to a low of $8.99 on monster volume. Basically what we have here is an oversold bounce since the relative strength index reading for MDRX is 17.74.

Traders should continue to look for an oversold bounce in MDRX as long as this stock is trending above its gap-down day high of $10.51 with strong upside volume flows. I would consider upside volume that’s near or well above 4.3 million shares as bullish. As long as MDRX is trending above $10.51 with strong volume, then this stock can continue to fill that massive gap-down.

I would avoid MDRX if its trending below that gap-down day high or below today’s low of $10.16 with heavy volume.

PhotoMedex

PhotoMedex (PHMD) provides integrated disease management and aesthetic solutions through laser and light-based devices and science-based skincare products. This stock is trading up 4% at $15.40 in recent trading.

>>5 Stocks Setting Up to Break Out

From a technical perspective, PHMD is ripping higher here and it’s triggering a near-term breakout above some overhead resistance at $15.11 on heavy volume.

Traders should continue to look for long-biased trades in PHMD as long as it’s trending above $15.11 with strong upside volume flows, and if it closes near its daily highs. I would consider any upside volume that’s near or well above 54,122 shares as bullish. If we get a strong close today, then look for PHMD to continue its uptrend towards its next significant overhead resistance level at $16.81 in the near future.

Traders should only consider long-biased traders in CYOU if it can manage to move back above its 50-day with strong volume. Look for a sustained move or close above $26.57 with volume that’s near or well above 297,700 shares. If we get that action soon, then CYOU could trend back towards its next significant overhead resistance levels at $28.05 to its 200-day moving average of $39.35.

Traders should now look for long-biased trades as long as ZAGG is trending above $12.35, and if it can close near its daily highs. If we get that action today, then look for ZAGG to continue its uptrend in front of its quarter toward its next significant overhead resistance level at $14.

Following its earnings report, traders should look for long-biased trades if ZAGG can trigger a breakout trade over $14 with volume. Look for a sustained move or close over $14 with volume that’s near or well above 1,124,510 shares. If we get that action, look for ZAGG to make a run at $16 to $17 or possibly much higher.

If we get that action today, look for CVV to make a run at its next significant overhead resistance level oat $16.06 in the near future.
