As an investor its worth striving to ensure your overall portfolio beats the market average. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term Akamai Technologies, Inc. (NASDAQ:AKAM) shareholders, since the share price is down 26% in the last three years, falling well short of the market return of around 46%.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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).

Akamai Technologies saw its EPS decline at a compound rate of 7.3% per year, over the last three years. The share price decline of 10% is actually steeper than the EPS slippage. So it seems the market was too confident about the business, in the past.

A Different Perspective

Akamai Technologies shareholders are down 16% for the year, but the market itself is up 14%. 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 5% per year over five years. 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.
