Allstate (ALL) Stock May Be Below Fair Value After AM Best Rating Affirmation

Simply Wall St·09/12/2026 07:20:36
Listen to the news

Allstate stock has delivered a very strong 147.9% gain over the past three years, yet current valuation checks still suggest the shares lean cheap rather than fully priced in.

  • The 147.9% return over three years puts Allstate among the stronger performers in the insurance group. This raises the question of how much upside is already reflected in today's valuation.
  • AM Best's affirmation of Allstate's A+ Financial Strength Rating can support confidence in future cash generation. However, any setback in underwriting margins would quickly feed back into what investors are willing to pay for the stock.
  • The broader valuation work points to Allstate screening as undervalued, with a high value score of 5 suggesting the current price does not fully reflect the business fundamentals.

The issue now is whether Allstate's strong multi year share price run has already captured most of that value, or if the current level still leaves meaningful room for further returns over time.

Is Allstate Still Cheap on Earnings?

P/E is usually the cleanest yardstick for an insurer like Allstate because earnings already reflect underwriting and investment results in one figure. Allstate trades on a P/E of 4.9x, which is less than half the Insurance industry average of 11.1x and well below the peer group on 10.3x. That is a wide gap for a large, established player.

The tailored fair P/E for Allstate sits at 7.3x, based on its earnings profile, scale and risk characteristics. The current 4.9x level is materially lower than that benchmark. This suggests that the stock price reflects a generous margin of safety on this measure. AM Best’s recent affirmation of the group’s A+ rating underlines that this low multiple is not simply a function of weak balance sheet quality.

On a P/E basis, Allstate stock appears undervalued compared with both its industry and the more tailored fair multiple.

The Bottom Line

Allstate still screens as undervalued on earnings, which puts the burden on the bear case to explain why the discount should persist. The market is effectively saying that concerns over margins, technology change and long term demand for auto cover outweigh the current profitability picture. The crux for investors is whether underwriting discipline and execution on cost and retention can hold up well enough for the P/E gap to close, or whether that gap is simply fair compensation for the structural risks already on display in the narratives above.
