Energy companies led U.S. stocks modestly lower Tuesday, erasing the small gains the market made a day earlier.

Disappointing results or outlooks from retailers and other companies also weighed on the market.

Utilities and consumer-focused companies like packaged food and beverage makers, restaurant chains, bucked the trend.

Investors had their eye on Washington D.C., where the House is expected to vote on its version of a major tax bill this week. Expectations that the tax overhaul will sharply lower corporate taxes have helped lift the market higher this year.

“We’re through earnings season, which was pretty good, with earnings up about 10 percent,” said Stuart Freeman, co-head of global equity strategy for Wells Fargo Investment Institute. “Now investors are waiting and watching to see what shape this tax reduction bill is going to take.”
