Stock prices ended the session little changed on Tuesday after concerns rose about the continuing economic crisis in Greece. The markets had originally opened higher on a positive housing report.

Private investors have developed quite an appetite for restaurant companies. In the past couple of weeks alone, two popular restaurant chains have been acquired by partnerships.

There was a pause yesterday in the aggressive selling on Wall Street that had seen the Dow Industrials fall in 12 of the previous 13 sessions. Buyers stepped back in, however, and the blue chip index added 135 points, its best day in more than a month. There was no real reason for the rally, especially in light of the big drop in shares of Facebook. The stock dropped $4.20 to just over $34 as investors decided to dump the shares after the debacle on Friday. The selling continues today with Facebook down another $2 in early trading, falling as low as $30.98.

Call it a Facebook fiasco. A week ago everybody wanted the stock, today they can't get rid of it fast enough. Early trading has the shares of the social media company falling below $34, a loss of more than $4 a share. What went wrong? That subject will probably be debated for years to come, but it really comes down to supply and demand. When it looked like the IPO was going to be priced at the high end of the offering range -- it came at $38 -- eligible sellers found it too tempting to turn down. That caused the size of the deal to go up by 25 percent in the last days before the IPO. Accordingly, it became easy for anyone who wanted the shares on the offering to get as much as they wanted. Then, when the stock failed to rally on Friday, the selling began and has carried over today.
