U.S. stocks showed signs of recovering in a volatile session on Wednesday, with major indexes paring their morning losses as strong earnings seemed to overshadow the impact of rising bond yields. The Dow Jones Industrial Average rose less than 0.1% while the S&P 500 was off 0.1% and the Nasdaq Composite Index was down less than 0.1%. All three had been solidly lower in early trading, with the S&P 500 nearly falling below a key technical level. One of the biggest boosts to the market came from Boeing Co. which rose 3.8% in the wake of stronger-than-expected results. The stock was one of the biggest boosts to both the Dow and the S&P 500. Also supporting stocks was Apple Inc. which rose 1.1%. Stocks are coming off a sharp decline in the previous session that was driven in part by the U.S. 10-year Treasury note's yield crossing 3%, a psychologically important level that raised concerns about corporate borrowing costs going forward.
