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.

Restoration Hardware

Restoration Hardware(RH) - Get Report, together with its subsidiaries, is engaged in the retail of home furnishings. This stock is trading up 1.7% to $94.77 in Friday's trading session.

Friday's Volume: 1.54 million
Three-Month Average Volume: 751,998
Volume Change: 396%

From a technical perspective, RH is ripping higher here after briefly dipping below its 50-day moving average of $89.83 with strong upside volume flows. This spike to the upside here is now quickly pushing shares of RH within range of triggering a big breakout trade above some key near-term overhead resistance levels. That trade will trigger if RH manages to take out some key near-term overhead resistance levels at $95.79 to $96.88 and then above more resistance at $97.76 with high volume.

Traders should now look for long-biased trades in RH as long as it's trending above $92.50 or above Friday's intraday low of $88.90 and then once it sustains a move or close above those breakout levels with volume that registers near or above 751,998 shares. If that breakout triggers soon, then RH will set up to re-test or possibly take out its next major overhead resistance level at its all-time high of $100.66. Any high-volume move above that level will then give RH a chance to make a run at $105 to $110 a share.

From a technical perspective, MANU is spiking notably higher here right above some near-term support levels at $15.50 to $15.40 and back above its 50-day moving average of $16.09 with above-average volume. This spike has now pushed shares of MANU right into its 200-day moving average of $16.59. Market players should now look for a continuation move to the upside in the short-term if MANU manages to take out its 200-day moving average of $16.59 with high volume.

Traders should now look for long-biased trades in MANU as long as it's trending above its 50-day at $16.09 or above those near-term support levels at $15.50 to $15.40 and then once it sustains a move or close above its 200-day moving average at $16.59 with volume that hits near or above 117,954 shares. If that move kicks off soon, then MANU will set up to re-test or possibly take out its next major overhead resistance levels at $17.50 to $17.72, or even $17.95 to $19.
