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.

Kate Spade

Kate Spade (KATE) , together with its subsidiaries, primarily designs and markets a range of apparel and accessories. This stock traded up 6.5% to $31.68 in Thursday's trading session.

From a technical perspective, KATE gapped up sharply higher here back above its 50-day moving average of $29.63 and briefly above its 200-day moving average of $32.40 with heavy upside volume flows. This sharp move to the upside on Thursday also briefly pushed shares of KATE into breakout territory, since the stock flirted with some key near-term overhead resistance levels at $32.47 to $32.80. Shares of KATE closed off its highs on Thursday of $33.40 to finish the trading session at $31.68. This stock is now starting to trend within range of triggering another major breakout trade. That trade will hit if KATE manages to take out some past overhead resistance at $33.88 with high volume.

Traders should now look for long-biased trades in KATE as long as it's trending above Thursday's intraday low of $31.35 and then once it sustains a move or close above $33.88 with volume that registers near or above 2.24 million shares. If that breakout hits soon, then KATE will set up to re-test or possibly take out its next major overhead resistance level at its 52-week high of $42.87.
