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. >>5 Big Stocks to Trade for Big Gains 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. 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 Stocks Under $10 Set to Soar 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. Sirius XM Radio Nearest Resistance: $4.20 Nearest Support: $3.80 Catalyst: Earnings >>5 Stocks Poised to Pop on Bullish Earnings Shares of satellite radio stock Sirius XM Radio ( SIRI) are trading more than 1.5% lower this afternoon, following the firm's mixed third-quarter earnings release this morning. SIRI added more than a half-million subscribers in the quarter, boosting its total subscriber count to 25.6 million listeners, a record high. Net income fell more or less in line with analysts' estimates, but 2014 guidance fell short, which is why shares are showing traders a modest decline. From a technical standpoint, SIRI still looks bullish. Shares are pulling back down to trendline support at the 50-day moving average, a level that's acted as a floor for shares since the middle of the summer. For investors in search of a good entry opportunity, it doesn't get much better than this.
