NEW YORK—Technology stocks are bearing the brunt of a recent market selloff, putting a spotlight on how an extended downturn in the sector could weigh on broader equity indexes.

After Monday’s sharp drop, the S&P 500 technology sector is down 6.7 percent since the overall S&P 500 closed at a record on Sept. 2, compared with a 5.2 percent decline for the broader index over that time.
