Another view on valuation
The fair value story built around earnings and growth expectations points to upside, but the current P/E of 31.8x tells a more cautious story. It sits below the wider US Capital Markets industry at 38.9x, yet well above peers at 18.3x and a fair ratio of 13.5x, which suggests meaningful valuation risk if sentiment cools.
When a stock trades this far above its fair ratio, any earnings wobble or shift in expectations can have an outsized impact on the share price. It is therefore worth asking whether current optimism leaves enough margin for error.
