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.>>Buy These 5 Rocket Stocks to Beat the Market With that in mind, let's take a look at several stocks rising on unusual volume recently. 500.com (WBAI - Get Report) provides online sports lottery services in the People's Republic of China.
