Software stocks had a rough Friday, and CrowdStrike fell 7.02%
CrowdStrike fell 7.02% on Friday to US$227.39. The cybersecurity company has lost 17.3% in a week, and 18.5% since it closed at US$278.86 on 6 October.
Its neighbours fared no better. Palo Alto Networks lost more than 7%, and Palantir, which sells data software to governments and companies, fell 7.22%. By Yahoo Finance's count, 43 of the 45 software stocks it tracks finished lower.
Cybersecurity copped the worst of it. The First Trust Nasdaq Cybersecurity fund, which holds the sector's big names, fell about 10% over the week. Yahoo Finance says that was its worst week since March 2020.
Two worries did the damage. The first is the one dragging on chipmakers: whether the money being poured into AI will earn a return, now that the 10-year Treasury yield sits at 5.09%.
The second is specific to security. On Tuesday a report said OpenAI plans to buy a cybersecurity startup. No target and no price were named, but investors took it as a sign that AI companies may build security into their own products.
nothing in CrowdStrike's business changed this week. The share price moved because investors changed their minds about what AI means for its customers. I'd want to see an AI company actually win a big security contract before treating that as a threat to the business.
