Volume is the market's heartbeat. On a normal day a penny stock trades thin and quiet — nobody's paying attention. When volume spikes to 3, 5, or 10 times its average, something is happening: a filing dropped, a deal was announced, insiders are moving, or the crowd is waking up. High volume means this ticker is getting attention which will most likely have a profound influence on price action. These are the tickers where the action is today — perhaps a reason to watch them closely. Check out these charts!
