Comcast Corp. (CMCSA) shares plunged nearly 13 percent on Friday, the most in over a year, after a morning analyst downgrade spooked investors.
While the specific firm was not immediately named, the ratings change was sufficient to trigger a significant sell-off. "The downgrade reflects concerns over slowing growth in the company's broadband and media divisions," a summary of the analyst's position noted.
The stock closed at $27.56, down 12.90% for the day. It touched a low of $29.66 earlier in the session, its largest intraday percent decrease since October 2025. The stock is now down 6.58% from the same time last year.
The sharp drop erases gains for the month and puts the stock in negative territory for the year. The move reflects broader investor anxiety over the future of traditional cable providers, as peer Charter Communications (CHTR) also saw its stock fall by over 25% on the same day.
The decline puts the stock at its lowest since early December 2025, testing its 200-day moving average, a key technical support level. Investors will be closely watching the company's upcoming earnings report on May 7 for any signs of a turnaround or further weakness.
