Stock Quotes in this Article: CX, O, SIRI

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.

>>Why the Fed's "Taper Tantrum" Doesn't Matter

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 the Pros Love This Summer

Sirius XM Radio

Nearest Resistance: $3.40

Nearest Support: $3.20

Catalyst: Technical Setup

>>5 Big Trades After the Fed Meeting

Satellite radio operator Sirius XM Radio (SIRI) is down just shy of 2%, driven lower on high trading volume by a bearish technical setup. Sirius XM has had a major about-face in the last two months, going from rallying hard in May to correcting just as hard in June. The rounding top pattern put into shares at the end of last month triggered a few weeks ago, and shares have been making an orderly descent ever since. I think it's early to try to build a position in SIRI right now.

Wait for the downtrend resistance line to get broken before jumping in.

Realty Income

Nearest Resistance: $43

Nearest Support: $40

Catalyst: Dividend Hike

>>5 Stocks Insiders Love Right Now

Retail REIT Realty Income (O) didn't just start selling off this week. Shares of the large landlord have been getting shellacked since the middle of May, when a downgrade from Goldman Sachs sparked selling. For income-seekers, one positive outcome from that is a higher dividend yield, currently at 5% for Realty Income. And with today's dividend announcement, that yield is continuing to increase.

Realty Income announced yesterday that it was hiking its monthly dividend payout from 18 cents to 18.15 cents. The shareholder pay raise is small, but coupled with the huge drop in shares over the last month, this stock's yield has become massive. I'd suggest waiting to build a position from here – we're still a little way off from $40 support.

Cemex

Nearest Resistance: $10.25

Nearest Support: $9.75

Catalyst: Latin America Proxy

>>5 Stocks Poised to Pop on Bullish Earnings

Newsflash: Unlike the recent weakness in the S&P 500, emerging-market stocks have been getting hammered for pretty much all of 2013. That's showing through in Mexican cement maker Cemex (CX) as it tests key support today. Cemex made a major swing in today's session, cracking all the way down to test key support at $9. Since then, it's rebounded back up to shorter-term support at $9.75 – if shares can hold that level until the close today, Monday may be a good time to jump into CX as a short-term buy.

Longer-term, resistance has been constraining CX to lower highs. Until that resistance line gets broken, I'd only recommend more experienced traders take a position in this stock.
