Datadog dropped roughly 2% in premarket trading on July 21 after Jefferies analyst Brent Thill cut the stock from Buy to Hold.

Datadog, Inc., DDOG

DDOG has climbed 94% year-to-date, and Thill’s note essentially says the easy money has been made. The stock was trading around levels well above Jefferies’ prior price target before the call.

The downgrade was not a bearish call on the business. Thill still raised his price target from $210 to $280. He just thinks the valuation has gotten ahead of the story.

At roughly 18x EV/CY27 revenue, DDOG carries a 4-turn premium to Snowflake. Thill said that leaves “little cushion for any execution slippage.”

Growth has been strong. Revenue growth re-accelerated from 25% in Q1 2025 to 32% in Q1 2026, which helped fuel the run-up. Jefferies’ thesis on DDOG as an AI beneficiary and category leader has played out, at least in the first half of 2026.

Valuation Raises Eyebrows

The P/E ratio currently sits at 674.87x. That’s not a typo. It reflects how far ahead of current earnings the market is pricing future growth.

DDOG’s GF Score stands at 83 out of 100, with a perfect 10/10 on growth. But its profitability score is just 4/10, which matters when multiples are this stretched.

Jefferies said it would look to get constructive again at a better entry point. That implies they see value in the name longer term, just not at current prices.

Insider Selling Adds to the Picture

Insiders have sold $378.2 million worth of stock in the past three months. There has been no insider buying reported in that period.

That kind of one-sided activity doesn’t always signal trouble, but it’s worth noting alongside the downgrade.

The broader Jefferies Q2 preview framed the market as moving away from blanket negative positioning toward a more fundamentals-driven setup.

The firm said its proprietary partner checks showed strong cloud demand and continued capacity shortages, supporting positive revisions across hyperscaler and infrastructure names.

But it cautioned that expectations are elevated and setups are “more nuanced where positioning and multiples are stretched.” That description fits DDOG fairly well right now.

Jefferies named Amazon, Microsoft, and Atlassian as preferred names heading into earnings. It also turned negative on Palantir, citing escalating comparisons and growing competition.

Thill’s new $280 price target represents a roughly 14% premium to where DDOG was trading before the downgrade landed.
