So what Despite reporting third-quarter revenue and adjusted earnings per share well ahead of analysts' estimates, the stock fell following the earnings release. The stock is down more than 7% since Datadog reported third-quarter results after market close on Tuesday. Investors may have been concerned about the company's decelerating revenue growth and several analysts' decisions to downgrade their price targets for the stock. A broader-market decline for many growth stocks on Friday likely provided fuel for further investor skepticism toward Datadog shares at their current valuation. Now what Investors should keep in mind that decelerating growth rates are normal for fast-growing companies like Datadog. Further, it's worth noting that while growth has slowed, Datadog is still growing very rapidly. Third-quarter revenue was up 61% year over year. Management was optimistic about Datadog's future in its third-quarter earnings release. "We continue to make meaningful [research and development] investments toward what is a very significant long-term opportunity," said Datadog co-founder and CEO Olivier Pomel. 10 stocks we like better than DatadogWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
