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 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 underway. And when there's a big catalyst, there's often a trading opportunity.

Without further ado, here's a look at three of today's names.

Sumitomo Mitsui Financial Group

Nearest Resistance: $6.60

Nearest Support: $6.10

Catalyst: Japanese Bank Stumbles

Japanese banks have been stumbling this week, a fact that's trickling into trading stateside with the American depositary receipt -- or ADR -- of Sumitomo Mitsui Financial Group ( SMFG). Sumitomo is one of the biggest financial services firms in Japan, making it an obvious choice for investors seeking out (or trying to avoid) exposure to financials in the land of the rising sun.

Despite an uptick in trading volume today, shares are only up around 2% as they bounce off of yesterday's August lows.

Shares of SMFG have been range-bound for the last couple of months. Until this stock can break outside of that $6.10 to $6.60 range, there isn't a trade here.

Idenix Pharmaceuticals

Nearest Resistance: $8

Nearest Support: $4.30

Catalyst: FDA Decision

>>5 Stocks Under $10 Set to Soar

Idenix Pharmaceuticals ( IDIX) is getting shellacked today, after announcing that the FDA was placing a traial for its lead hepatitis C compound on hold. While Idenix's compound didn't have any issues, a similar compound under trial from Bristol-Myers Squibb ( BMY) did cause a serious health issue in at least one patient. The similarities between the drugs are enough to suspend IDIX's contender -- and send shares down 30% today.

Idenix is the prototypical falling knife here. Today's gap down is a big move lower for shares, but it's not necessarily any sort of a bottom at this point.

Opportunistic buyers should wait for shares to catch a bid before trying to jump on a bargain opportunity. The nearest meaningful support level is the stock's 52-week low at $4.30.

Nearest Resistance: $74

Nearest Support: $71

Catalyst: Earnings

Last up is retail giant Wal-Mart ( WMT), one of the " 5 Consumer Stocks Hedge Funds Love" right now. They're probably just not loving today's price action.

Wal-Mart is down around 3% as I write, the result of earnings that, while strong, fell short of what analysts had been expecting. The disappointment broke shares down below the bottom of an otherwise bullish technical setup, opening the door to more downside until WMT touches support at $71. I wouldn't go back and buy this stock unless it can push through resistance at $74; that's too close for an upside barrier otherwise.

Wal-Mart is one of Warren Buffett's holdings.
