Another View: What Do Valuation Ratios Say?

Looking at how Pentair trades, its price-to-earnings ratio is 30.1 times. This means it is more expensive than both its industry average (24.5x), the peer average (22.6x), and even the market-implied fair ratio of 25.4x. This premium suggests that the market is already factoring in optimism, which could limit future returns if things do not play out perfectly. Is there potential for a correction, or will strong results justify paying more?
