Short-sellers.

An emergency order by Wall Street regulators to combat "bear raids" on vulnerable financial stocks, launched by traders that profit when stocks go down, goes into effect last Monday.
But the rule's main intent — to help stem quick, steep stock declines that create financial panic — actually kicked in right after the Securities and Exchange Commission announced investor protections on last Tuesday night.
Wall Street pros credit the ruling, which makes it harder to engage in a trading technique known as "naked" short selling, with helping fuel a 534-point three-day rally on the Dow Jones industrials and a 21% gain for the S&P 500 financial sector.
The SEC crackdown targets short sellers, who hope to make money by selling borrowed shares and buying them back at lower prices. A naked short sale occurs when the trader does the trade without actually borrowing the shares, which can intensify the downward pressure on a stock.
The SEC order requires short sellers to take possession of the stock. Previously, a short seller could simply ask a broker to locate the shares, which made it easier and faster to profit in a falling market.
The SEC's move is designed to combat what critics say are the rumors, market manipulation and runs on stocks similar to the events that led to the demise of investment bank Bear Stearns in mid-March.
It also likely prompted traders involved in naked short selling to reverse their bets by buying back shares — pushing stocks up sharply in the process.
