6 Stocks Rising on Huge Volume

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.

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 tracking well above their average daily trading volume.

Dendreon ( DNDN) is a biotechnology company focused on the discovery, development and commercialization of therapeutics that may improve cancer treatment options for patients. The stock is trading up 8.9% at $13.45 in recent trading.

Today's Volume: 18 million

Average Volume: 6.8 million

Volume % Change: 268%

From a technical standpoint, shares of DNDN are very close to triggering a big breakout trade if this stock can manage to sustain a move and close above some past overhead resistance at $13.95. A high-volume move and close over $13.95 will push DNDN into position to start filling its massive gap down from back in August of 2010 from over $30.

Volume today is already well above its average action, so watch for a close over $13.95.

Questor Pharmaceuticals ( QCOR), a biopharmaceutical company, provides prescription drugs for the treatment of auto-immune diseases. The stock is trading up 8% at $42.11 in recent trading.

Today's Volume: 2.4 million

Average Volume: 1.1 million

Volume % Change: 241%

Shares of QCOR are ripping higher today after the company announced sales of its H.P. Acthar Gel that exceeded analyst expectations. The company shipped 3,360 vial of the gel vs. 1,680 shipped in the fourth quarter of 2010.

From a technical standpoint, QCOR is starting to gap up big today back above its 50-day moving average of $42.25 on heavy volume. Traders should now watch for a sustained move and close above $42.25 to signal that this stock wants to re-test some major overhead resistance at close to $46.

I would consider it a major breakout if QCOR can take out $46 with volume in the coming days or weeks.

Questcor shows up on recent lists of 3 Low-PEG, High-Momentum Stocks and 5 Drug Stock Winners of 2011.

Netflix ( NFLX) is an Internet subscription service streaming television shows and movies. The stock is trading up 6% at $92.29 in recent trading.

Today's Volume: 13.3 million

Average Volume: 8.45 million

Volume % Change: 222%

Shares of NFLX are soaring higher today after the company said it will begin its push into the U.K. and Ireland, marking the start of a European expansion that will push it into a loss this year but will attract new customers in the long run.

From a technical standpoint, NFLX is approaching another big breakout trade if the stock can manage to take out some past overhead resistance at $93.84 with volume. Volume today is already well above the average action and the stock has already hit a daily high of $93.58.

A move and close over $93.84 with volume should be considered very bullish since this will bring a large gap down from $120 into play from back in October of 2010.

Netflix, one of TheStreet Ratings' top-rated online retail stocks, shows up on a list of 6 Tech Stocks to Avoid in 2012 but was also featured recently in " 5 Big Stocks to Trade for Gains."

Shares of Tornier N.V. are surging higher today after the company announced preliminary fourth-quarter sales gains of 12.7% and full-year 2011 sales gains of 14.9%.

From a technical standpoint, TRNX has started to challenge its 50-day moving average of $18.67 today on high volume. Market players should now watch for a sustained high-volume move and close above $18.67 and then $18.72 to trigger a breakout trade.

If we get that action soon, then look for TRNX to challenge $20 to $22.32 (its 200-day) if the volume continues to track in strong on the up days.
