NEW YORK >> Wall Street closed its third winning week in the last four with a quiet finish on Friday.

The S&P 500 edged down by a whisper, less than 0.1%, after setting its all-time high the day before. The Dow Jones Industrial Average fell 142 points, or 0.3%, and the Nasdaq composite edged up by less than 0.1% to add its own record.

Norfolk Southern chugged 2.5% higher after an AP source said it’s talking with Union Pacific about a merger to create the largest railroad in North America, one that would connect the East and West coasts. Any such deal, though, would likely face tough scrutiny from U.S. regulators. Union Pacific’s stock fell 1.2%.

The heaviest weight on the market, meanwhile, was Netflix, which fell 5.1% despite reporting a stronger-than-expected profit. Analysts said it wasn’t a surprise given the stock had already soared 43% for the year so far coming into the day, six times more than the gain for the S&P 500.

American Express likewise delivered a better-than-expected profit report, but its stock lost 2.3%. Analysts pointed to slowing growth in some underlying trends, such as the number of cards it issued.

Exxon Mobil sank 3.5% and also tugged on the market. It had been challenging Chevron’s $53 billion deal to buy Hess, but an arbitration ruling in Paris about Hess assets off Guyana’s coast allowed the buyout to go through. Chevron fell 0.9% after losing an early gain.

Stronger-than-expected profit reports for the spring did help several stocks rally. Charles Schwab climbed 2.9%, Regions Financial jumped 6.1% and Comerica added 4.6%.

All told, the S&P 500 slipped 0.57 to 6,296.79 points. The Dow Jones Industrial Average dropped 142.30 to 44,342.19, and the Nasdaq composite rose 10.01 to 20,895.66.
