These days it's easy to simply buy an index fund, and your returns should (roughly) match the market. But in our experience, buying the right stocks can give your wealth a significant boost. For example, the Arrow Electronics, Inc. (NYSE:ARW) share price is up 84% in the last five years, slightly above the market return. In comparison, the share price is down 2.5% in a year.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

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.

During the five years of share price growth, Arrow Electronics moved from a loss to profitability. That would generally be considered a positive, so we'd hope to see the share price to rise.

A Different Perspective

While the broader market gained around 19% in the last year, Arrow Electronics shareholders lost 2.5%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 13% 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider for instance, the ever-present spectre of investment risk. We've identified 4 warning signs with Arrow Electronics , and understanding them should be part of your investment process.
