"We simply attempt to be fearful when others are greedy, and to be greedy only when others are fearful."
-- Warren Buffett

Of all the Oracle of Omaha's orations, this one holds a special place in Foolish investors' hearts. When looking to bag a bargain, a panicked sell-off by jittery investors offers you a great chance to snap up stocks on the cheap.

In the short term, professional traders' pessimism can become a self-fulfilling prophecy. Desperate institutions lower their asking prices to get rid of a stock, prompting buyers' bid prices to fall in tandem, creating the very price decline that both sides feared in the first place -- until the selling stops.

Until it does, savvy investors can "get greedy," snapping up bargains from these fearful sellers. (Assuming they really are bargains.) In today's column, we'll see which stocks Wall Street's motivated sellers are most frantic to unload. Once we've compiled this shopping list of potential picks, we'll check them against the collective intelligence of Motley Fool CAPS.

Dag-gone! Somebody really has it in for banks. Actually, it looks like a whole lot of somebodies. Not only is Wall Street actively selling banking shares, but every one of the banks on today's list also gets just a single star (our lowest rating) from us mere-mortal investors on CAPS as well.

Fortunately, this list also includes one company whose business model does not consist of issuing $100,000 "liar loans" to people wanting to buy the McMansion of their dreams. Medical Action Industries' business is much more down-to-earth. This Hauppauge, N.Y.-based company manufactures mundane but essential "disposable medical products" such as bedpans and soap dishes, biohazard bags and hospital gowns. I know -- sexy! But read on, as we examine...

The bull case for Medical Action Industries
For such a boring company, MedAct sure attracts a lot of attention from the very best investors on CAPS -- our "All-Stars." Let's start off with an introduction from PsychoDr, who wrote back in 2006 that:

They are one of the smaller players in this area [medical products], but continue to grow annually through well timed acquisitions and seemless integration of acquired companies. Production of disposable medical goods results in a continuous stream of recurrent purchasing by their clients and acquisitions allow the company to offer a wider array of products. Profit margin is around 7%, however, the company prides itself on being the low price leader (like Wal-Mart (NYSE:WMT)) and sales continue to climb yoy.

glenvar echoes the good doctor's thoughts, arguing:

The beauty [of the products MedAct makes] is that they have to be purchased and replaced. The stock has gotten creamed due to the fact that petroleum products are used in the manufacturing of the products, and the price of oil is rising so high [but] it just announced record sales and profits, and they have no debt. Way oversold.

Haugurafpeningum believes that: "With aging population this one should outperform." Then again, that same aging population is attracting attention from much larger rivals like Becton, Dickinson (NYSE:BDX) and Covidien (NYSE:COV). Watch your back, MedAct.

Making money from the mundane
In Rule No. 7 in One Up on Wall Street, famed uber-investor Peter Lynch urges us to seek out "depressing" stocks. I humbly submit that a maker of bedpans qualifies. Reading the laundry list of banality that is MedAct's stock in trade, you could almost overlook the fact that this company sells for a mere 13 times earnings, yet is expected to grow at a 14% clip over the next half-decade. Real value hounds who dig even deeper may discover that MedAct's superior cash generation ability gives it an even cheaper price-to-free cash flow ratio.

Long-story short, MedAct is cheap, folks. If it gets much cheaper than this, I may have to buy some shares for myself.

Time to chime in
Of course, I'm open to persuasion to the contrary. Does Wall Street know something that the rest of Fooldom does not? If you see something we're missing, come on over to Motley Fool CAPS and clue us in.
