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 SoarNational Bank of Greece Nearest Resistance: $2.30 Nearest Support: $1.20 Catalyst: Fitch Upgrade >>5 Stocks Insiders Love Right Now First up is National Bank of Greece ( NBG), a stock that's up more than 14% as I write today after ratings firm Fitch upgraded it and a number of other Greek banks. NBG is approaching nearly three-times its normal trading volume midway through this afternoon. While the upgrade is promising from a fundamental standpoint, investors looking to dip a toe in NBG should think again: this stock is supremely volatile and fraught with headline risk right now. NBG's chart is insane -- the $2 billion banking stock looks like a microcap in the middle of a pump and dump campaign right now. At this point, National Bank of Greece is plowing its way to new multi-month highs, but there's still considerable selling pressure in the mid-$2 range. With support far below NBG's current print, I'd recommend all but the most nimble traders avoid this name altogether right now.
