Why Is FASTLY INC A (FSLY) Stock Down Today?

Fastly Inc A (FSLY) shares fell 9.80% to close at $26.43. The primary driver appears to be a correction following a significant twelve-month rally, as the stock had returned 241.5% through October 9, 2026, significantly outpacing the 17.0% gain for the S&P 500.

What Happened

The decline occurred despite recent positive corporate developments. Fastly announced an expanded partnership with Jio Platforms to support the digital economy in India. Additionally, the company integrated Supertab Connect’s AI bot classification and RSL licensing tools into its Compute platform, allowing publishers to identify AI crawlers and publish machine-readable licensing terms. These updates were reported in the last 36 hours.

However, the stock’s recent momentum has been tempered by insider activity. In the last 90 days, there have been no insider buys, while 29 sales totaling $33.9 million were recorded. CTO Artur Bergman filed three separate sale transactions in September 2026, with the most recent filing dated September 30. The company remains unprofitable, with a trailing twelve-month EPS of -0.53 and a net margin of -11.8%, despite revenue growth of 20.4%.
