Jason, they banned all short sales of those stocks (except for "certain bona fide market makers" and some option exercises). From http://www.sec.gov/rules/other/2008/34-58592.pdf:
IT IS ORDERED that, pursuant to our Section 12(k)(2) powers, all persons are prohibited from short selling any publicly traded securities of any Included Financial Firm.
I applaud the SEC's courageous move to ban short selling. Isn't that brilliant? I wonder why they didn't think of that during the Great Depression.
However, I feel that this valiant effort does not go far enough.
All selling of stocks should be banned. Once you buy a stock, you have to hold it forever.
Sure, this might make the market a little less liquid. But once stock prices can only go up, we'll all be rich!
Or maybe we should just try something simpler: pass a law making it illegal for stock prices to go down.
