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.

From a technical perspective, CARB ripped higher here right off some near-term support at $10.25 with above-average volume. This stock has been uptrending for the last few weeks, with shares moving higher from its low of $9.17 to its intraday high of $10.85. During that uptrend, shares of CARB have been consistently making higher lows and higher highs, which is bullish technical price action. That move has now pushed shares of CARB within range of triggering a near-term breakout trade. That trade will hit if CARB manages to take out Friday's intraday high of $10.85 and then once it clears both its 50-day and 200-day moving average at $11.07 with high volume.
