The S&P 500 and Dow Jones Industrial Average edged higher Wednesday in a choppy trading session as signs of progress on a stimulus package lifted investor sentiment.
The indexes opened lower, before paring their losses over the course of the day.
The S&P 500 finished the day up 6.56 points, or 0.2%, to 3669.01, a record close.
The market has been propelled higher in recent weeks by optimism that Covid-19 vaccines will help accelerate the economic rebound.
That has led to a blockbuster rally, spurred, in part, by a jump in stocks that are sensitive to economic growth.
