4 Stocks Rising on Unusual Volume

MADISON, 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 today.

From a technical perspective, FIO is bouncing sharply higher here right off of $14 with above-average volume. This move is quickly pushing shares of FIO within range of triggering a near-term breakout trade. That trade will hit if FIO manages to take out some near-term overhead resistance levels at $15 to $15.90 with high volume.

Traders should now look for long-biased trades in FIO as long as it's trending above $14 or above some more near-term support at $13.35 and then once it sustains a move or close above those breakout levels with volume that hits near or above 3.65 million shares. If that breakout triggers soon, then FIO will set up to re-fill some of its previous gap down zone from earlier this month that started at around $18.

Inter Parfums

Inter Parfums ( IPAR) manufactures, markets and distributes an array of fragrances and fragrance related products. This stock is trading up 3.8% to $30.10 in recent trading.
