Shares of several companies, including monday.com, RingCentral, and BlackLine, are falling. The list of affected companies appears to be broader, with other outlets reporting declines in shares of 8x8, AppLovin, Twilio, Datadog, Box, and others. However, there is some inconsistency in the reports, with some companies, such as Atlassian and Zeta Global, being reported as both trading down and up.
