Stock futures fell in premarket trading Friday following a mixed session in which coronavirus concerns pushed investors further into tech shares.

Dow Jones Industrial Average futures implied an opening decline of nearly 200 points. ET. S&P 500 and Nasdaq-100 futures also traded lower.

The Nasdaq Composite closed at an all-time high during regular trading as Amazon jumped 3% to a record. Microsoft, Apple and Netflix were also higher.

But the rest of the market struggled. The Dow dropped more than 300 points, erasing its week-to-date gains. The S&P 500 dipped 0.6%.
