Two of the three major U.S. stock indexes closed at record highs Tuesday as tech shares recovered from two-day losses.

The Nasdaq added 44 points to finish at 6,220 points after it had plummeted 2.3 percent in the last two trading sessions.

The Dow rose 92 points to end the day at 21,328 and the S&P 500 gained 10 points to 2,440 -- each records.

Tech giants Amazon and Facebook each jumped nearly 2 percent, while Google's parent company, Alphabet, and Microsoft gained about 1 percent apiece.

The financial world will focus Wednesday on the two-day meeting of the Federal Reserve, after which the central bank will announce its interest rate decision and Chair Janet Yellen will share the bank's outlook on the economy.
