Stocks stumble as Nasdaq sinks and leaders tumble.

Dow Jones futures and S&P 500 futures fell after weak economic data raised recession fears for a second straight session. Declining stocks decisively beat winners, with many leading stocks such as On Holding, MarketAxess, and PagerDuty tumbling. Tesla skidded for a third straight day, triggering the automatic sell rule. Bank stocks came under more pressure, while medical names and other defensive growth or defensive plays looked relatively strong. Investors should be looking to protect profits and cut losses.
