We think all investors should try to buy and hold high quality multi-year winners. While not every stock performs well, when investors win, they can win big. To wit, the NPK International Inc. (NYSE:NPKI) share price has soared 499% over five years. If that doesn't get you thinking about long term investing, we don't know what will. Also pleasing for shareholders was the 12% gain in the last three months.
While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.
To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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).
During the five years of share price growth, NPK International moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Dive deeper into the earnings by checking this interactive graph of NPK International's earnings, revenue and cash flow.
We're pleased to report that NPK International shareholders have received a total shareholder return of 70% over one year. That gain is better than the annual TSR over five years, which is 43%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It is all well and good that insiders have been buying shares, but we suggest you check here to see what price insiders were buying at.
