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.

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.

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 Bargain Stocks to Play the Resurgent U.S. Consumer

A big bit of M&A news is coming from Pittsburgh, home to ketchup giant H.J. Heinz ( HNZ). The firm announced today that it would be acquired by a group of investors led by Warren Buffett's Berkshire Hathaway ( BRK.B). The deal gives HNZ shareholders $72.50 in cash, a price that's a 20% premium to yesterday's close.

But if you didn't own HNZ last night, don't bother buying it now. As I write, there's a 1-cent risk premium priced into the deal, making the merger arbitrage opportunity completely non-existent for late-to-the-game buyers. This stock isn't likely to deviate from that offer price for the foreseeable future.

>>4 Loser Stocks Poised for a Comeback in 2013

Shareholders of Constellation Brands ( STZ - Get Report) are winning big today after Anheuser-Busch InBev ( BUD) announced that it would sell rights for Grupo Modelo's U.S. brands to Constellation in order to jump the regulatory hurdles being imposed on BUD's full acquisition of the Latin American brewing giant. The news gives Constellation some of the country's most popular beer brands at a bargain price, a necessary sacrifice BUD had to make to get the bigger piece of the Grupo Modelo's business. The news is sending STZ to new highs today, up more than 36%.

Making new highs is significant from an investor psychology standpoint because it means that everyone who has bought shares in the last year is sitting on gains. As a result, the "back to even" mentality is less of a concern than it would be for a name with a higher proportion of shareholders sitting on losses. For late-to-the-game buyers, though, I'd recommend sitting on the sidelines until STZ pushes above today's high water mark. A correction might be in order before the weekend.

Mondelez International

Nearest Resistance: $28
Nearest Support: $26
Catalyst: Q4 Earnings Miss

$47 billion snack foods giant Mondelez International ( MDLZ - Get Report) isn't getting buoyed by its chocolate exposure this Valentine's Day. Instead, the Kraft ( KRFT) spinoff gapped down more than 3% today after releasing numbers for the last quarter. Clearly, Wall Street isn't liking them.

The gap-down puts Mondelez in a less-than-awesome technical position. With shares smack-dab in between resistance at $28 and support at $26, this stock could still move materially before any sort of high probability trading opportunity pops up. For that reason, it's best to wait for MDLZ to establish some kind of price action at this new level before trying to trade this stock.
