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.

SolarCity (SCTY) designs, manufactures, installs, maintains, monitors, leases, and sells solar energy systems to residential, commercial, government, and other customers in the U.S. This stock is trading up 6.5% to $55.58 in Monday's trading session.

  • Monday's Volume: 2.57 million
  • Three-Month Average Volume: 2.21 million
  • Volume % Change: 170%

From a technical perspective, SolarCity is ripping sharply higher here right off its 20-day moving average of $53.94 and back above its 200-day moving average of $54.35 with strong upside volume flows. This bullish spike to the upside on Monday has also pushed shares of SolarCity into breakout territory, since the stock took out some near-term overhead resistance at $55.

This move is now starting to push shares of SolarCity within range of triggering another big breakout trade. That trade will hit if this stock manages to take out some key overhead resistance levels at its 50-day moving average of $57.28 to some more near-term resistance at $58.40 with high volume.

Traders should now look for long-biased trades in SolarCity as long as it's trending above its 200-day at $54.35 or above its 20-day at $53.94 and then once it sustains a move or close above those breakout levels with volume that hits near or above 2.21 million 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 $62 to $64 a share.

  • Volume % Change: 236%

From a technical perspective, Jarden is jumping notably higher here right above some near-term support at $54 with bullish upside volume flows. This spike to the upside on Monday has now pushed shares of Jarden into breakout territory, since the stock has cleared some near-term overhead resistance just above $55 and it has now printed a new 52-week high. Market players should now look for a continuation move to the upside in the short-term if this stock manages to take out Monday's intraday high of $55.90 with high volume.

Traders should now look for long-biased trades in Jarden as long as it's trending above some near-term support at $54 and then once it sustains a move or close above $55.90 with volume that hits near or above 1.46 million shares.
