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.>>5 Stocks Under $10 Set to Soar 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. >>5 Big Trades to Take in December With that in mind, let's take a look at several stocks rising on unusual volume today. Shenandoah Telecommunications Shenandoah Telecommunications ( SHEN) provides integrated voice, video and data communications services to end-user customers and other communications providers. This stock closed up 3.6% at $24.18 in Friday's trading session. Friday's Volume: 184,000
Three-Month Average Volume: 115,970
Volume % Change: 65% From a technical perspective, SHEN spiked higher here with above-average volume. This stock just formed a double bottom chart pattern, since buyers stepped in to support the stock over the last month at $22.17 and at $22.19. Shares of SHEN have now started to spike higher off $22.19 and it's quickly moving within range of triggering a near-term breakout trade. That trade will hit if SHEN manages to take out some near-term overhead resistance levels at its 50-day moving average of $25.19 to more near-term overhead resistance at $25.44 with high volume. Traders should now look for long-biased trades in SHEN as long as it's trending above Friday's low of $23.23 or above more support at $22.19 and then once it sustains a move or close above those breakout levels with volume that's near or above 115,970 shares. If that breakout hits soon, then SHEN will set up to re-test or possibly take out its next major overhead resistance levels at $27.02 to its 52-week high at $29.15.
