Since everyone loves a winner, it's reasonable to assume that everyone hates a loser -- everyone but short-sellers, at least. These contrarian investors bet that hot stocks are primed to fall, aiming to turn their pessimism into profits.

However, since the SEC has instituted a temporary ban on short-selling on hundreds of financial stocks -- a term that becomes more broadly defined daily -- short-sellers haven't had much to do. This week we'll take a look at companies on the New York Stock Exchange with shares short representing the largest percentage of a company's float. But this week we'll also see whether the short ban is having any impact on keeping the shares afloat.

Combining that with the collective intelligence of Motley Fool CAPS, we'll see which of these stocks Fools believe have the power to make short work of short-sellers.

Float = shares outstanding, minus shares controlled by insiders, restricted stock, and shares held by 5% owners. Short-selling ban went into effect Sept. 18.

Of course, this isn't a list of stocks to buy or short. These stocks could have serious problems that warrant their short interest, but they might also be stricken by short-term troubles. Only Foolish due diligence will tell you for certain. Our 115,000-plus-strong CAPS community offers a good place to start.

The short list
Only three of the 10 stocks above -- Downey, FirstFed, and Greenhill -- were on the protected list, yet they still declined by an average of almost 18%. The remaining seven companies that were left to the vagaries of the short-sellers were off only an average of 3% since the ban went into effect. While certainly not a scientific sampling, it seems to underscore the belief that weakness in stock prices had little to do with short-sellers and more to do with investor concern over an individual company's shaky finances.

Top-rated CAPS member TheGarcipian doesn't see the short-selling ban as being able to overcome the severe problems of the housing market that led to Downey Financial plummeting originally:

Going down with Downey... again. This company was hurting before the latest downturn in the housing & financial markets. I do NOT expect the current state of events to improve this company's bottom line. (I wish I'd thumbed this down yesterday as I'd planned -- darn work got in the way -- because it's getting pummeled today 9/26/2008, down nearly 50% from its price just two days ago).

Short-selling ban or not, CAPS member balancedinvestor doesn't see FirstFed Financial surviving. It simply has too many negative aspects working against it:

this will eventually go to 0 - modify as many loans as you can and change your game plan but the end result wil be the same :). CA, option arm, high NPAs, increasing broker deposits-all negatives

Some CAPS All-Stars have a hard time believing that homebuilder Hovnanian will be able to recover from the devastation that has wrecked the housing market. All-Star member floridabuilder says it might not go bankrupt, but because it is so weakened, Hovnanian will be unable to capitalize on any opportunities that may present themselves:

[Hovnanian] reported earnings a little bit ago and I figured I would throw some thoughts out there..... [Hovnanian] is not going bankrupt in 2008..... 2009 is a different story... given the Sept order trends of the builder group backlogs … are going to shrink....

....... a 3.5% gross margin before impairments means massive future impairments... which directly hits equity and their debt to equity ratio is 3rd worst in the industry.... their backlog is somewhere in the middle vs. their peer group (neutral opinion).... I would suspect that 1/2 to 2/3 of their owned lots are finished... so that will provide them positive cashflow through 2009
