 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.

Let's take a look at a number of stocks rising on unusual volume today. They are all recording volume in midday trading that is already at least 50% above their average trading volume for a full day.

Cal-Maine Foods

Cal-Maine Foods (CALM) is a producer and marketer of shell eggs in the U.S. The stock is trading up 4.5% at $35.81 in recent trading.

Today’s Volume: 136,000

Average Volume: 80,323

Volume % Change: 328%

Shares of CALM are spiking higher today after the company said its second-quarter profit rose more than 50% due to strong demand for eggs and higher average selling prices. Cal-Maine’s net income jumped to $23.3 million, or 97 cents per share, from $15.2 million, or 64 cents per share, last year.

From a technical standpoint, CALM has gapped up big today and broken out above some past overhead resistance levels at $34.83 to $34.86 on heavy volume. Traders should now watch for the next major breakout to trigger if CALM can sustain a move and close above $36.39 on high volume.

Look for volume that registers near or above 80,323 on a move over $36.39 to confirm that this stock wants to trend much higher in the near future.

From a technical standpoint, AWAY is bouncing big today with volume off of some oversold conditions with volume. The current relative strength index (RSI) reading for AWAY is under 30, which indicates an oversold condition. Since the stock is bouncing here right around some previous support at $19.94, it’s very possible that a bottom is being put in for AWAY.

Market players should watch for the next long trade to trigger if AWAY can take out $22 with volume. Look for volume that’s near or above 276,675 shares on a sustained move and close over $22.
