NEW YORK (AP) — The Standard & Poor’s 500 index eked out its second small gain of the week Wednesday as investors pored over the latest earnings reports.

Norfolk Southern climbed after the railroad company said its fourth-quarter profit rose 24 percent, better than Wall Street analysts had forecast. TE Connectivity, an electronics company, was the biggest gainer in the S&P 500 after its earnings beat analysts’ expectations and the company posted a strong earnings outlook for the second quarter.
