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. 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." >>5 Stocks Setting Up to Break Out 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. >>5 Breakout Trades to Benefit From the 'January Effect' Fusion-IO Fusion-IO ( FIO), a provider of data center solutions, is trading up 5.4% at $20.06 in recent trading. Today's Volume: 3.07 million Average Volume: 2.82 million Volume % Change: 122% From a technical perspective, FIO is bouncing here right above some near-term support at $18.85 with above-average volume. This stock recently broke below some key near-term support levels at $21.63 to $21.14, after it failed at its 50-day moving average of $22.73. That slide has pushed FIO into oversold territory, since its relative strength index hit 30. Oversold can always get more oversold, but it's also an area where a stock can produce a powerful upward bounce from. Traders should now look for long-biased trades in FIO as long as it's trending above that recent low of $18.85 with strong upside volume flows. I would consider any upside volume day that registers near or above its three-month average action of 2.82 million shares. If FIO can maintain that trend, then this stock has a great chance of rebounding back towards its next significant overhead resistance levels at $22 to $22.73. Any move above $22.73 will then put its 200-day at $24.09 into range for shares of FIO.
