Cybersecurity stock Zscaler just had its worst day ever, plunging over 30% after the company warned of a slowdown and announced a major leadership change in its sales division.

## Idea

When a high-flying tech stock drops over 30% in a single day due to internal shakeups and weak future guidance, it often signals a deeper loss of confidence rather than just a temporary dip. The enormous trading volume indicates that large institutions are aggressively selling their shares. This kind of severe chart damage usually takes months to repair, as investors who bought at higher prices will look to sell into any brief bounces. Betting against the stock aims to capture the continued downward drift as the bad news continues to sink in.
