Major moves in volume can signal unusual activity, such as insider buying or selling -- or buying or selling by "superinvestors."

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.
