Grocery stores, big retailers, and food makers and distributors plunged Friday. Energy companies rose while other stocks were little changed. The S&P 500 inched up a fraction of a point to 2,433. The Dow added 24 points to a record high of 21,384. The Nasdaq fell nearly 14 points to 6,151.

A proposed tax on imports is central to the House GOP plan to lower the overall corporate tax rate.

But the tax faces strong opposition from retailers, automakers and the oil industry, and a growing number of Republicans in Congress have come out against it. They worry that it will increase the cost of imports, increasing consumer prices.
