By buying an index fund, you can roughly match the market return with ease. But if you choose individual stocks with prowess, you can make superior returns. Just take a look at Centene Corporation (NYSE:CNC), which is up 21%, over three years, soundly beating the market return of 11% (not including dividends).

While the stock has fallen 5.9% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, Centene achieved compound earnings per share growth of 6.1% per year. We note that the 6% yearly (average) share price gain isn't too far from the EPS growth rate. Coincidence? Probably not. That suggests that the market sentiment around the company hasn't changed much over that time. Quite to the contrary, the share price has arguably reflected the EPS growth.

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 Centene's earnings, revenue and cash flow.

A Different Perspective

Investors in Centene had a tough year, with a total loss of 2.6%, against a market gain of about 22%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 3% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
