Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. Investors in Everspin Technologies, Inc. (NASDAQ:MRAM) have tasted that bitter downside in the last year, as the share price dropped 21%. That falls noticeably short of the market return of around 28%. On the other hand, the stock is actually up 6.3% over three years. In the last ninety days we've seen the share price slide 29%. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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).

Even though the Everspin Technologies share price is down over the year, its EPS actually improved. It's quite possible that growth expectations may have been unreasonable in the past.

It's fair to say that the share price does not seem to be reflecting the EPS growth. So it's easy to justify a look at some other metrics.

Everspin Technologies managed to grow revenue over the last year, which is usually a real positive. Since the fundamental metrics don't readily explain the share price drop, there might be an opportunity if the market has overreacted.

A Different Perspective

Everspin Technologies shareholders are down 21% for the year, but the market itself is up 28%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Even so, be aware that Everspin Technologies is showing 4 warning signs in our investment analysis , and 1 of those is a bit unpleasant...
