Wow! It is a temporary ban on shorting financial stocks.

Maybe short-selling should be banned completely. What do you think?

The U.S. Securities and Exchange Commission took what it called "emergency action" on Friday and temporarily banned investors from short-selling 799 financial companies.

The temporary ban, aimed at helping restore falling stock prices that have shattered confidence in the financial markets, takes effect immediately.

Short sellers borrow stock with the aim of selling it, then buy it back at a lower price, hoping to pocket the difference. The commission said short sellers add liquidity to the markets during normal conditions, but recent unbridled short selling has contributed to the recent tailspin in the stock market.
