Taking a different angle, Proto Labs is currently trading at around 80 times its earnings. This figure is much higher than both the US Machinery industry average of 24.3x and its peer group average of 37.7x. In addition, this multiple sits well above the fair ratio of 36.8x that regression analysis suggests the market could revert to. Such a premium price reflects high expectations for future growth, but it also introduces the risk that any disappointing results could spark a sharp correction. Will investors continue to justify paying such a lofty price?
