Simply Wall St·09/29/2026 23:21:49
Listen to the news

Bank of America has delivered a 3 year share price gain that puts real money on the line for long term holders, which naturally raises the question of whether the current valuation is supported by the returns the bank earns on its capital.

  • Over the past 3 years the stock has returned about 127.9%, so any view on Bank of America now hinges on whether that move still lines up with the profitability of every dollar the bank has put to work.
  • Management is ramping up spending on artificial intelligence across platforms such as Erica and treasury tools like AskGPS and CashPro, which can influence how efficiently capital is used and how much extra return the franchise can squeeze from its existing asset base.

For investors, the debate is whether the returns Bank of America earns on its capital are strong and durable enough to make today's share price look well supported on that basis alone.

Does Bank of America Look Undervalued on Excess Returns?

The Excess Returns model looks at how profit on each dollar of equity compares with the return investors demand, then builds an intrinsic value from that gap. For Bank of America, the inputs show book value of $39.34 per share and an average return on equity of 12.64%, against a cost of equity of $3.47 per share. The model uses a stable earnings figure of $5.48 per share and a stable book value of $43.38 per share, both drawn from future estimates by 13 analysts, to anchor those return assumptions.

That framework produces an excess return of $2.02 per share, which means the business is expected to earn more on its equity base than the model treats as the required charge for risk. The Excess Returns projections put Bank of America's estimated intrinsic value substantially above the current share price of $54.96. The valuation gap stems from these sustained surplus returns on capital rather than aggressive growth forecasts. Bank of America's plan to double its AI budget next year helps explain why some investors may see room for those excess returns to persist if the technology spending continues to support efficiency and fee income.
