Comcast (CMCSA) Stock Stays Cheap On Its 45% Five Year Slide

Simply Wall St·10/26/2026 14:31:17
Listen to the news

Comcast has seen its share price slide over a multi year stretch, even as recent news has sparked a short term bounce. With the stock last closing at US$22.69, the question for investors is whether that price can be explained by the earnings power of the business.

  • Over the past 5 years the share price has fallen 44.8%, which puts the focus squarely on whether current earnings still justify even this lower valuation.
  • Recent results highlighted pressure in the core broadband unit alongside growth in streaming and wireless, a mix that can reshape assumptions about future profitability and the timing of cash generation from Comcast's earnings base.
  • Your read on Comcast is one view; the desks covering it have another. See what analysts think Comcast's shares could be worth.

The stock's next move may depend on whether Comcast's current earnings are strong and reliable enough to support the price investors are paying today.

Does Comcast Look Undervalued on Earnings?

The P/E ratio gives a clean read on how the market prices Comcast's current earnings stream. On this measure, Comcast trades at about 7.1x earnings, compared with roughly 15.2x for the wider telecom sector and around 12.7x for peers in its comparison set. That is a sizeable gap between what investors are willing to pay for each dollar of Comcast profit and what they pay across the industry.

Because of this gap, and based on a tailored fair multiple that factors in Comcast's own growth profile, margins, scale and risk, the stock screens on the undervalued side of that range. The recent Q3 beat on earnings, despite pressure in broadband and a planned separation of NBCUniversal and Sky, has not closed that discount, so the shares still change hands at a lower earnings multiple than many comparable telecom groups. Explore the numbers behind Comcast's P/E valuation.
