Cybersecurity company Zscaler just had its worst day ever, crashing 31% after reporting cautious financial guidance and shaking up its sales leadership. The stock has now lost half its value over the past year.

## Idea

Zscaler dropped 31% in a single session — its worst day ever — after issuing what management called 'prudent' guidance alongside a sales leadership shakeup. Companies don't replace their sales chiefs when things are going well, and the cautious outlook suggests revenue growth is decelerating faster than Wall Street expected. The stock has already been cut in half over the last year, meaning investor confidence was already fragile. Huge one-day selloffs like this tend to be followed by more selling as analysts downgrade and institutional holders reduce positions. This isn't a dip to buy — it's a stock under distress.
