Cybersecurity company Zscaler just suffered its worst day ever, losing nearly a third of its value in a single session after warning investors that growth is slowing and shaking up its sales leadership.

## Idea

Zscaler plunged 31% — its worst single day ever — after reporting what management called 'prudent' guidance alongside a sales leadership shakeup. The company has already lost half its value over the past year, suggesting investors have been steadily losing faith. When a high-multiple software stock cuts guidance and reorganizes its sales team at the same time, it usually signals deeper problems than one bad quarter. Analyst downgrades and forced selling from funds that can no longer hold the stock tend to pile on in the days after a crash of this magnitude. The sheer weight of trapped shareholders looking to exit on any bounce could keep the stock under pressure for weeks.
