NEW YORK: US stocks closed higher on Wednesday, adding to gains after the Federal Reserve repeated a pledge to use its "full range of tools" to support the economy but cautioned that the outlook "will depend significantly on the course of the virus."

At the end of its two-day policy meeting the Fed said it will keep its interest rate target range until it is confident the economy has weathered the coronavirus pandemic and is on track for maximum employment and price stability goals.

While strategists said they found no surprising decisions after the meeting, many pointed out that the Fed's focus on the virus highlighted the uncertainties it faces.

"The Fed is putting health again front and center in its statement, which is impactful and meaningful, especially when we're waiting on a bipartisan agreement on the fifth round of the CARES Act. It's a bit ominous, to be frank," said Nela Richardson, investment strategist at

St. Louis-based Edward Jones.

But Richardson noted the "commitment to do whatever it takes to get the economy going again" and a recognition the economy has improved and "come up from the bottom."

The Dow Jones Industrial Average rose 160.29 points, or 0.61%, to 26,539.57, the S&P 500 gained 40 points, or 1.24%, to 3,258.44 and the Nasdaq Composite added 140.85 points, or 1.35%, to 10,542.94.

All 11 major S&P sectors ended the day higher with the energy and financial sectors leading percentage gains.

Wall Street's major indexes had already been higher before the Fed commentary as investors anticipated earnings reports due on Thursday from Amazon.com Inc, Facebook Inc, Apple Inc and Alphabet's Google.

These companies were among the biggest boosts for Nasdaq even as the chief executives of all four companies also faced jabs from lawmakers at a congressional hearing on antitrust issues.

Investors were also focused on contentious negotiations in Washington around what should go into government's next coronavirus relief plan.
