Why is Datadog stock sliding today?
Datadog (DDOG) shares fell 5% to $259.31 after reports of a $4B offer for Upwind Security, which is seeking $300M at a $3.8B valuation. The deal's uncertainty and profit-taking followed a 24% rally driven by a Bernstein upgrade. Morgan Stanley reiterated a Buy rating with a $300 target, but bearish options activity increased. The Nasdaq's 3% drop added to the pressure.
