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 a number of stocks rising on unusual volume today.

Tesla Motors

Tesla Motors (TSLA) designs, develops, manufactures and sells electric vehicles and advanced electric vehicle powertrain components. This stock is trading up 3.8% at $36.01 in recent trading.

Today’s Volume: 1.2 million

Average Volume: 1.08 million

Volume % Change: 124%

From a technical perspective, TSLA has started to move above some near-term overhead resistance today at $35 with decent volume. This move now puts the stock within range of triggering a major breakout. That breakout will trigger once TSLA takes out its all-time high of $36.42.

A high-volume move and close above that level should set this stock up for significant upside, since it will mean that TSLA is trading in all-time-high territory. Traders should look for long biased trades once TSLA closes over $36.42 with decent volume.
