As Google traded sharply lower and was halted in the mid-afternoon, Bloomberg's Dominic Chu noted that competitors in Google's ad and mobile phone markets like LinkedIn ( LNKD ), Apple ( AAPL ) and Facebook ( FB ) traded down, but bounced off session lows. "Google halted, but $LNKD $FB $AAPL near, but off session lows on heels of $GOOG earnings & sales miss," wrote Chu on Twitter. According to Bloomberg, Google blames publisher R.R. Donnelley for the early earnings release and says it will continue to hold its earnings call at 4:30 p.m. eastern time. R.R. Donnelley's shares were off nearly 1% to $10.76 in Thursday trading, climbing back from intraday losses in excess of 7%.
