Comcast (CMCSA) Stock Could Be A Bargain After A 47% Fall

Comcast stock has had a tough run over the last few years, yet the current valuation checks still lean in its favour. After years of weak share price performance, the question for investors is whether the recent business momentum in media and connectivity is now better reflected in the price.

Comcast shares are down 46.7% over 5 years, which means long term holders have seen a significant erosion in value even as the business continues to evolve. Growth in media assets like Peacock and Universal, along with ongoing broadband and mobile bundling, can support earnings power, while continued broadband customer losses remain a key risk for how much investors are willing to pay for that income stream. On Simply Wall St's checks, Comcast screens as undervalued in 5 of 6 tests, which indicates the broader valuation framework currently leans cheap for the stock 5.

The stock's next move may depend on whether the market starts to price Comcast closer to what these valuation checks suggest or continues to focus on its weaker share price record.

Find out why Comcast's -15.3% return over the last year is lagging behind its peers.

Is Comcast Still Cheap on Earnings?

The P/E ratio is a useful lens for Comcast because earnings remain a key anchor for how investors judge this mix of connectivity and media assets. Comcast currently trades on a P/E of about 7.8x. That sits below the telecom industry average of roughly 16.8x and also below a peer group average of about 11.1x.

Simply Wall St's fair P/E estimate for Comcast is around 13.4x, which reflects what investors might expect to pay given its earnings profile, industry, size and risk factors. The current P/E is materially lower than that fair ratio, so the shares screen as undervalued on this earnings-based check. Despite recent headlines about Peacock reaching profitability and NBCUniversal's planned spin off, the market is still pricing Comcast at a discount to both peers and this tailored benchmark.

On the P/E multiple, Comcast stock appears undervalued compared with both its sector and a more customised fair value estimate.NasdaqGS:CMCSA P/E Ratio as at Jul 2026

The Bottom Line

Comcast screens as undervalued on market multiples, with the P/E sitting well below both the sector average and a tailored fair ratio estimate. That gap only really matters if earnings from media assets and connectivity can stay resilient enough for the discount to narrow over time. Broader valuation checks lean supportive, yet the stock also carries clear execution risk around broadband trends and how much investors trust the earnings mix. The real decision for you is whether the current discount reflects an overly cautious market or a fair response to those structural questions.
