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 Poised to Pop on Bullish Earnings 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 Big Stocks to Sell Now 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 Rocket Stocks to Buy as Stocks BounceFacebook Nearest Resistance: $25 Nearest Support: $23.50 Catalyst: Analyst Upgrade >>3 Tech Stocks Under $10 to WatchFacebook ( FB) is seeing a pop on high volume today after an analyst upgrade at Jeffries sparked buying in the social networking stock this morning. Facebook has been a cautionary tale of late. Its IPO was fraught with missteps, and the scores of retail investors who bought the stock on its first day of trading continue to sit on hefty losses today. It's too early to tell is today's 6% jump can change that. Facebook's drop below support at $25 was significant -- it meant that the glut of buying pressure that's previously been down at that level got taken out by increasingly eager sellers. And while today's bounce is keeping FB off of the year-to-date lows set yesterday, we're still under newfound resistance at $25. I couldn't recommend buying unless Facebook can catch a bid above that level this week.
