Shares of technology companies rose as traders rotated back into the sector, chasing recent gains.

One brokerage said the tech sector is once more gathering upward momentum after falling out of favor earlier this year. "The theme of 2021 has been rotation, rotation, rotation," said Scott Brown, technical strategist at brokerage LPL Financial.
