Stock Quotes in this Article: MGI, SEIC

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 Poised for Big Breakouts

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.

>>4 Big Stocks on Traders' Radars

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

From a technical perspective, MGI ripped higher here right off its 50-day moving average of $20.65 with above-average volume. This move is quickly pushing shares of MGI within range of triggering a major breakout trade. That trade will hit if MGI manages to take out some near-term overhead resistance at $23.39 to its 52-week high at $24.88 with high volume.

Traders should now look for long-biased trades in MGI as long as it's trending above its 50-day at $20.65 or above more near-term support at $20 and then once it sustains a move or close above those breakout levels with volume that hits near or above 139,470 shares. If that breakout triggers soon, then MGI will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are its next major overhead resistance levels at $29 to $30.

Keep in mind that MGI is set to report earnings on July 25. Look to play that breakout action before the quarter and then after as long as the stock continues to uptrend once earnings are out.

This breakout could be setting up SEIC for much higher prices, since it entered new highs with above-average volume.
