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 several stocks rising on unusual volume today. >>5 Stocks Poised for Big Breakouts SunPower SunPower ( SPWR) is a vertically integrated solar products and services company that designs, manufactures and delivers high-performance solar electric systems worldwide for residential, commercial and utility-scale power plant customers.
