BALTIMORE ( Stockpickr) -- Put down the 10-K filings and the stock screeners. It's time to take a break from the traditional methods of generating investment ideas. Instead, let the crowd do it for you. From hedge funds to individual investors, scores of market participants are turning to social media to figure out which stocks are worth watching. It's a concept that's known as "crowdsourcing," and it uses the masses to identify emerging trends in the market. >>5 Stocks Setting Up to Break Out Crowdsourcing has long been a popular tool for the advertising industry, but it also makes a lot of sense as an investment tool. After all, the market is completely driven by the supply and demand, so it can be valuable to see what names are trending among the crowd. While some fund managers are already trying to leverage social media resources like Twitter to find algorithmic trading opportunities, for most investors, crowdsourcing works best as a starting point for investors who want a starting point in their analysis. Today, we'll leverage the power of the crowd to take a look at some of the most active stocks on the market today. >>5 Stock Trades for S&P 1,700 These "most active" names are the most heavily-traded names on the market -- and often, uber-active names have some sort of a technical or fundamental catalyst driving investors' attention on shares. That's especially true now that earnings season is officially underway. And when there's a big catalyst, there's often a trading opportunity. Without further ado, here's a look at today's stocks. >>5 Stocks Under $10 Set to SoarAruba Networks Nearest Resistance: $17 Nearest Support: $12.36 Catalyst: Earnings, Guidance Miss Shares of networking equipment maker Aruba Networks ( ARUN) are getting shellacked this afternoon, down more than 25% as I write following a first-quarter loss and lower guidance announced after the bell yesterday. The firm earned 11 cents per share for the quarter, a penny short of the 12 cents that analysts were expecting -- but the guidance dip is what's doing the stock in today. From a technical standpoint, Aruba Networks is broken. The stock gapped down hard on this morning's open, shoving shares all the way down to support at their $12.36 52-week low. While it's positive that shares are catching a bid down there, it's a little too early to say that the selloff is over. After all, shares have halved in the last month alone.
