Rising bond yields and another pullback in energy shares were too much for the stock market to overcome Wednesday. And while most actual earnings reports have at least been in line with expectations, disappointing guidance has failed to revive leadership in key sectors, most notably tech. The Nasdaq Composite finished with a loss of 9.40 points, or 0.45%, at 2100.05, weighed down by disappointing sales guidance from online retailer Amazon.com ( AMZN) yesterday. (Shares of Amylin ( AMLN) and Biogen Idec ( BIIB) were down sharply in after-hours trading after both biotechs reported disappointing results.) Meanwhile, the Dow Jones Industrial Average finished down 32.89 points, or 0.32%, at 10,344.98. The blue-chip average was under pressure from weakness in Boeing ( BA), whose earnings disappointed, and Exxon Mobil ( XOM) which tracked crude prices. Crude slid $1.78 to $60.66 per barrel following a bearish inventory report, erasing most of a $2 rally on Tuesday. The S&P 500 dropped 5.16 points, or 0.43%, to 1191.38. Technical traders noted that the S&P pulled back after failing to convincingly breach its 200-day moving average at 1199. The broad average retreated after touching an intraday high of 1204. Adding pressure on the stock market was a continued surge in bond yields , which have broken through previous resistance levels amid rising inflation expectations. The benchmark 10-year Treasury bond fell 14/32 while its yield, which moves inversely, rose to 4.59%, its highest level since March. The stock market, meanwhile, is giving headaches to market strategists, who are paid to make sense of it and position their firms' money to profit from it. Technically, many trend-watchers believe the market has been oversold for more than a week and a half now. While there have been sharp gains since, they've been met with quick reversals. One reason for this has been earnings, says Chris Johnson, market strategist at Schaeffer's Investment Research. While a majority of companies reporting so far have either met or beat expectations, there have been high-profile disappointments in forward guidance.
