Wall Street slides over 2% as tech rout deepens; Fed meeting eyed

Dow Jones Industrial Average was down 764.89 points, or 2.23%, at 33,599.61, the S&P 500 was down 115.61 points, or 2.62%, at 4,294.52

US stock indexes slid on Tuesday, with the S&P 500 on track to confirm a correction as a selloff in technology stocks ahead of the Federal Reserve's policy meeting overshadowed upbeat results from blue-chip companies including IBM and 3M.

The benchmark index came close to confirming a correction on Monday before bouncing back late in the session. A correction is confirmed when an index closes 10% or more lower than its record closing level.
