CrowdStrike’s best day ever, and four peers in their own top six, on one session

Enterprise software repriced together on August 27, 2026, and the size of each move matters less than where it sits in that company’s own record. CrowdStrike rose 20.3%, the largest single day in its entire listed life of 1,812 sessions since its June 2019 debut. Okta rose 28.6%, its second-best of 2,359 sessions since listing in April 2017. Veeva rose 15.3%, fourth of 3,234 since October 2013. Palo Alto Networks rose 12.8%, sixth of 3,545 since July 2012. Salesforce rose 22.6%, its second-best of the 4,188 sessions our record holds — that record starts at the end of 2009 and Salesforce listed in 2004, so this is its best day since 2009 rather than a lifetime mark.

Every one of the five opened with a gap and none of the five filled it: Okta opened 23.6% above the prior close, Veeva 12.5%, Salesforce 11.9%, CrowdStrike 9.9% and Palo Alto Networks 5.7%, and no session low reached back to the previous day. The wider tape did not join in. The S&P 500 gained 0.66% while its equal-weight version fell 0.30%, and 348 of the index’s 497 members closed lower. We are not attributing a cause here: several of these companies report in late August, but this page makes no earnings claim it has not verified at the filing.
