Valuation
Valuation signal
Fairly valuedClosing price of 11 Nov 2026, used by the daily score.
In our model the price counts as cheap below $65.53 and expensive above $196.59 (uncertainty very high, based on the price swings of the past year).
The two parts of the fair value come to $99.49 (cash-flow model) and $97.10 (industry comparison), and the gap between them shows how uncertain the estimate is. The price is slightly below both parts; given how much the stock swings, that still counts as fair.
Calculated with a cost of equity of 12.3%. At 13.3% the fair value would be $92.01, at 11.3% it would be $106.33.
Valuation metrics
Half from the cash-flow model, half from earnings times the industry P/E (38.9).
