Stock Quotes in this Article: AA, MU, BBRY

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 Stocks Poised for Breakouts

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.

>>5 Rocket Stocks Ready for Blastoff

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.

Micron Technology

Nearest Resistance: N/A

Nearest Support: $18

Catalyst: Technical Setup

>>4 Tech Stocks Under $10 to Watch

First up is perennial high-volume name Micron Technology (MU). Micron is seeing higher-than-normal volume this afternoon on the heels of new 52-week highs in shares. Micron has been a stellar momentum name all year in 2013, and it continues to hit new high water marks as the year progresses. While traders may want to avoid holding over earnings on October 10, this week could still be a good time to enter a trade in MU.

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. If you decide to take the trade, I'd recommend keeping a tight stop in place.

BlackBerry

Nearest Resistance: $8

Nearest Support: $7.50

Catalyst: Taxes, Buyout Talks

>>5 Big Trades to Take Right Now

BlackBerry (BBRY) is another name that gets consistent attention from traders -- not all of it good. But today, the beleaguered cell phone maker is up close to 4% this afternoon following reports that a who's who of tech sector giants are considering throwing their hats in the ring to acquire the firm. At the same time, news that BBRY is due to receive a half-billion-dollar tax refund, a reprieve from the staggering losses that the firm has been reporting to Wall Street.

Despite the buying today, shares of BBRY look anything but bullish. Shares are having trouble catching a bid above a relatively weak resistance level at $8, and $7.50 support isn't far enough away or strong enough to give shareholders much comfort. If BBRY can hold above $8, then it might make a nice short reversal trade, but only nimble market participants need apply.

Alcoa

Nearest Resistance: $8.20

Nearest Support: $7.70

Catalyst: Earnings

>>5 Earnings Stocks Everyone Hates -- but You Should Love

Alcoa (AA) announces its third-quarter earnings tomorrow, a move that officially kicks off earnings season to end the year. Speculation over AA's performance is triggering high volume in shares today, as traders look to exit their positions ahead of a big headline risk item, and gamblers load up ahead of a market-moving event. Alcoa has been pretty good at underwhelming Wall Street with its numbers in 2013, so we'll soon see if this quarter is any different.

The technicals in Alcoa look pretty messy right now too. While support looks fairly strong at $7.70 an abundance of spotty resistance levels overhead could make upside challenging for Alcoa tomorrow unless it really impresses investors. Alcoa sets the tone for earnings, so it'll be important to watch how investors react to the numbers.
