KeyCorp (KEY) Stock Could Be 47% Undervalued Despite Its 117% Run

Listen to the news

KeyCorp has delivered a 117.0% share price gain over the past three years, which puts fresh focus on what investors are really paying for. The question now is whether that price tag lines up with the returns the bank earns on the capital it puts to work.

  • The 117.0% move over three years means anyone looking at KeyCorp today is effectively pricing in a very different future for the returns it can generate on its balance sheet than they were a few years ago.
  • For a regional bank that depends heavily on how efficiently it turns deposits and loans into profit, the sustainability of those returns on equity and invested capital can heavily influence what counts as a reasonable entry price.
  • What if you looked at KeyCorp through its earnings instead? See what KeyCorp's 11.7x P/E says about the price.

The issue now is whether the recent share price level is supported by the returns KeyCorp is earning on its capital base.

Does KeyCorp Look Undervalued on Excess Returns?

The Excess Returns model looks at how efficiently KeyCorp turns its equity base into profits above the return that shareholders require. Instead of centering on dividends or short term earnings surprises, it focuses on what those excess profits might be worth over time compared with the current $20.72 share price.

For KeyCorp, the inputs point to a bank expected to generate returns on equity that sit above its implied cost of equity. Book Value is $16.14 per share and the Stable Book Value estimate is $16.96 per share. Stable EPS is $2.04 per share based on Return on Equity estimates from 9 analysts. The model treats the Cost of Equity as $1.24 per share and the Excess Return as $0.79 per share, which is where most of the valuation work happens.

Average Return on Equity of 12.02% suggests the business is modeled to earn more on its equity than investors are assumed to require. This supports a higher intrinsic worth than a bank earning only its cost of capital. Because the Excess Returns projections put KeyCorp's estimated intrinsic value substantially above the current share price, the model implies the market is not fully crediting those forecast excess profits at $20.72 per share.
