Zscaler drops 31% in a single day — wait for a green candle, then buy the bounce
Cybersecurity company Zscaler just had its worst trading day ever, losing 31% in a single session after reporting cautious future guidance and shaking up its sales leadership. The stock has now lost half its value over the past year.
Idea
A 31% single-day crash is an emotional overreaction more often than not. Zscaler's business didn't evaporate overnight — the sell-off was triggered by cautious forward guidance and a sales reorganization, not a fundamental breakdown. Historical patterns show that extreme one-day drops of 25%+ in large-cap tech frequently see a snap-back rally within a week as value hunters and short-sellers taking profits create buying pressure. The key is to wait for the first sign of stabilization — one green candle — before stepping in, and to keep the trade small and short-duration since the downtrend could resume.
