The concentrated buying by three active managers suggests a shared thesis on Datadog's fundamentals or growth trajectory. Monitor upcoming earnings for revenue and customer count trends to validate the thesis. The 45-day reporting lag means the cluster may have already been unwound — watch for insider trading patterns (Form 4) for corroboration.
