Track your investments for FREE with Simply Wall St, the portfolio command center trusted by over 7 million individual investors worldwide. After a 155.8% total return over the past 5 years, Bank of Montreal stock now trades at levels where the Excess Returns intrinsic value estimate and market multiples both point to pricing that looks broadly in line with fundamentals rather than clearly cheap. At the same time, the bank carries a low overall value score, which suggests the current valuation leaves less room for error than in the past. Over 5 years, Bank of Montreal has returned 155.8%, which puts today's valuation in the context of a long and strong run already behind existing shareholders. New initiatives such as BMO Insurance's AI enhanced SmartDecision underwriting tool can support expectations for earnings durability, while questions around how long current sector valuations can be maintained remain a key risk for the stock's pricing. Bank of Montreal passes only 1 of 6 valuation checks, so on a broad set of metrics it leans more expensive than outright bargain. The issue now is whether Bank of Montreal's recent share price level already reflects most of the good news, or if there is still enough valuation support for further upside. Find out why Bank of Montreal's 70.6% return over the last year is lagging behind its peers. Where Does Bank of Montreal Sit on Excess Returns? The Excess Returns model looks at whether Bank of Montreal is earning more on its equity than the return investors require. Here, analysts expect stable earnings power of about CA$15.83 per share on a stable book value base of roughly CA$119.10 to CA$119.96 per share, with an average forecast return on equity of 13.29%. Against an estimated cost of equity of CA$9.26 per share, the model calculates excess return of CA$6.57 per share and rolls that forward to an intrinsic value estimate of about CA$255.83 per share. With the stock recently around CA$254.46, Bank of Montreal screens as only about 0.5% undervalued, suggesting the current price already aligns closely with the equity return assumptions built into the Excess Returns model. The recent 40% share price gain highlighted in coverage of the Big Six banks helps explain why the market is no longer pricing in a large margin of safety versus intrinsic value. Overall, the Excess Returns workup indicates that Bank of Montreal stock now appears roughly fairly valued, with only a slight tilt toward undervalued on this model.
