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.

With that in mind, let's take a look at several stocks rising on unusual volume today.

At last check, JIVE has hit an intraday high of $17.75 on volume that’s well above its three-month average action of 651,386. Traders should now look for long-biased trades once JIVE takes out $18 to $18.63 with volume. Look for a sustained move or close above those levels with volume that’s near or above 651,386 shares. If we get that action soon, then JIVE has a great a chance of re-testing its 50-day moving average of $21.35.

At last check, NLNK has hit an intraday high of $13.78, which is also a new 52-week high on strong volume. Traders should continue to look for long-biased trades as long as NLNK is trending near or above $13.67 with strong upside volume flows.
