Another View: Valuation Using Market Ratios

Taking a step back, Pentair’s current price-to-earnings ratio is 29.3x. That is notably higher than the US Machinery industry average of 24.2x and also above its own fair ratio of 25.3x. The market could move toward this fair ratio. This suggests investors may be paying a premium for the stock today, which could limit future upside if expectations are not met. Does this premium make sense in light of future growth, or is there more risk priced in than meets the eye?
