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 Set to Soar 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 Rocket Stocks You Should Buy as Stocks Drop 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 Poised for BreakoutsVale Nearest Resistance: $18 Nearest Support: $17 Catalyst: Technical Setup Vale ( VALE) is seeing some strong volume of its own today, as traders watch closely for Vale to test a critical support level at $17. Shares of the $87 billion metal mining stock have been slammed since the start of the new year, and today's price action is threatening sending the stock even lower. $17 has acted as a strong price floor for VALE over the course of the last six months, but if shares push below it, traders have a signal that this stock can't catch a bid anymore.
