Why It’s Moving

Zscaler is moving on renewed analyst confidence as investors lean into its cybersecurity growth narrative
- Analyst sentiment remains constructive, with multiple firms reiterating Buy ratings and double-digit upside estimates, reinforcing the view that Zscaler’s growth story is still resonating with Wall Street.
- Fresh target updates over the past few weeks show analysts leaning on the company’s subscription model and security platform expansion, which suggests investors are still pricing in durable demand rather than a one-off quarter.
- The stock is reacting more to expectations than to a new company-specific catalyst in the last 7 days, so the move is being driven mainly by the broader cybersecurity growth trade and the market’s willingness to pay up for recurring revenue.

Western Digital slips as analysts warn the rally may be running ahead of reality
- Analysts have turned more cautious on Western Digital after a fresh downgrade, arguing the stock’s recent rally already reflects a lot of the good news.
- The bearish case centers on stretched expectations in the hard-drive and memory cycle, where pricing strength may not be as durable as investors had hoped.
- That concern has pushed the stock lower as traders reassess whether the company can keep delivering the growth already embedded in the share price.
