DELAFIELD, Wis. (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 recently.

MTS Systems

  • Monday's Volume: 49,000
  • Three-Month Average Volume: 66,497
  • Volume % Change: 177%

MTS Systems  (MTSC - Get Report) is a global supplier of test systems and position sensors. This stock is trading up 2.2% to $57.94 in Monday's trading session.

From a technical perspective, MTS Systems is moving modestly higher and displaying relative strength versus the overall market weakness with decent upside volume flows. This trend to the upside on Monday is now starting to push shares of MTS Systems within range of triggering a near-term breakout trade above some key overhead resistance levels. That trade will trigger if this stock manages to take out some near-term overhead resistance levels at its 20-day moving average of $57.99 to more resistance levels at $60.02 to $60.20 a share and then above its 50-day moving average of $60.66 a share with high volume.

Traders should now look for long-biased trades in MTS Systems as long as it's trending above some near-term support at $56 or above its recent low of $54.35 a share then once it sustains a move or close above those breakout levels with volume that hits near or above 66,497 shares. If that breakout triggers soon, then this stock will set up to re-test or possibly take out its next major overhead resistance levels at $64 to $65.70 a share.

From a technical perspective, Juno Therapeutics is ripping higher here right off its 20-day moving average of $39.27 with decent upside volume flows. This display of relative strength versus the overall market weakness is starting to push shares of Juno Therapeutics within range of triggering a big breakout trade above some key near-term overhead resistance levels. That trade will trigger if this stock manages to take out some near-term overhead resistance at its 50-day moving average of $42.03 to some more near-term overhead resistance levels at $44 to $44.25 with high volume.

Traders should now look for long-biased trades in Juno Therapeutics as long as it's trending above its 20-day moving average of $39.27 or above or above more key near-term support at $37.25 and then once it sustains a move or close above those breakout levels with volume that hits near or above 1.93 million shares.
