Why It’s Moving

Datadog is gaining traction as fresh analyst optimism reinforces the 2026 upside narrative.
- Analysts have turned more constructive into early August, with Argus raising its Datadog target to $324 and keeping a bullish view, signaling growing confidence that the company can sustain demand and execution into 2026.
- Recent analyst updates have clustered around higher targets and positive ratings, which suggests investors are focusing on Datadog’s ability to keep monetizing cloud monitoring and observability spending rather than on short-term volatility.
- The latest move looks more like a sentiment boost than a company-specific shock, with the stock benefiting from a favorable analyst backdrop even as broader expectations remain anchored to steady earnings growth and AI-related cloud usage.

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.
