Wall Street was mixed as disappointing results from companies including IBM and Coach left investors uneasy about stock valuations.

Of the 81 S&P 500 companies that have posted results so far this season, 70 percent have beaten estimates for profit and 64 percent have exceeded sales projections, according to data compiled by Bloomberg.
Shares of IBM, last down 3.5 percent, led the decline in the Dow.
IBM reported that revenue dropped 5.5 percent to US$27.7 billion in the fourth quarter and said the company's executives will forgo their bonuses.
"While we made solid progress in businesses that are powering our future, in view of the company's overall full year results, my senior team and I have recommended that we forgo our personal annual incentive payments for 2013," Ginni Rometty, IBM chairman, president and chief executive officer, said in a statement.
Shares of Coach sank, last down 6.9 percent, amid concern about a persistent slide in sales and market share in North America.
"Weakness in our North American women's bag and accessories business offset strong growth in Men's, footwear, and robust results in emerging Asian markets and Europe," Victor Luis, chief executive officer of Coach, said in a statement. "We continued to be disappointed by our performance in North America, which was impacted by substantially lower traffic in our stores and by our decision to limit access to our e-factory flash sales site."
