MADISON, Wis. ( 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. Often when above-average volume moves into an equity, it precedes a large spike in volatility.

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 Rocket Stocks to Buy for Dow 15,000 Westlake Chemical Westlake Chemical ( WLK) is a manufacturer and marketer of basic chemicals, vinyls, polymers and fabricated products.
