Another View: Rich Multiples, Different Message

That 1% gap between the current share price and the $71.67 fair value is one lens. Another is the current P/E of 65.6x, which is well above both the US Machinery industry at 27.3x and the peer average at 36.4x, and more than double the fair ratio of 29.9x.

This kind of gap can matter in practice, because if the market edges closer to that 29.9x fair ratio over time, the share price could lag even if earnings keep improving. The question for you is whether the recent earnings strength justifies living with that valuation risk, or not.
