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. >>4 Reasons to Buy Stocks in 2013 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 Huge Stocks to Trade for Gains in March 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 Hated Earnings Stocks Poised to PopCiena Nearest Resistance: $18 Nearest Support: $16.50 Catalyst: Surprise Profit A surprise first-quarter profit is spiking shares of communications stock Ciena ( CIEN) today, with shares up 16% as I write this afternoon. Analysts had expected a net loss for the quarter, but the firm actually earned 12 cents per share. Ciena has already seen three times its normal daily volume halfway though Thursday's market session. Shares of Ciena had been consolidating sideways for the last quarter and change, but today's massive gap up changes that. The move also puts $18 resistance within reach this month as the broad market pushes through to new highs. While risk is outsized right now in CIEN with shares so close to resistance, that tradeoff flips once resistance gets taken out. I'd recommend being a buyer on a move through $18.
