While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Proto Labs was able to grow its EPS at 15% per year over three years, sending the share price higher. In comparison, the 24% per year gain in the share price outpaces the EPS growth. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. It is quite common to see investors become enamoured with a business, after a few years of solid progress.

A Different Perspective

Proto Labs shareholders are down 36% for the year, but the market itself is up 3.8%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 5.9%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
