The simplest way to benefit from a rising market is to buy an index fund. But if you buy individual stocks, you can do both better or worse than that. Investors in O-I Glass, Inc. (NYSE:OI) have tasted that bitter downside in the last year, as the share price dropped 42%. That contrasts poorly with the market return of 30%. At least the damage isn't so bad if you look at the last three years, since the stock is down 30% in that time. The falls have accelerated recently, with the share price down 27% in the last three months. 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.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

O-I Glass fell to a loss making position during the year. Buyers no doubt think it's a temporary situation, but those with a nose for quality have low tolerance for losses. Of course, if the company can turn the situation around, investors will likely profit.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. This free interactive report on O-I Glass' earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

A Different Perspective

Investors in O-I Glass had a tough year, with a total loss of 42%, against a market gain of about 30%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 4% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for O-I Glass you should know about.
