The past three years for Charter Communications (NASDAQ:CHTR) investors has not been profitable

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 Charter Communications, Inc. (NASDAQ:CHTR) shareholders, since the share price is down 40% in the last three years, falling well short of the market return of around 30%. Even worse, it's down 8.6% in about a month, which isn't fun at all. However, we note the price may have been impacted by the broader market, which is down 4.0% in the same time period.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Although the share price is down over three years, Charter Communications actually managed to grow EPS by 13% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or else the company was over-hyped in the past, and so its growth has disappointed.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

The company has kept revenue pretty healthy over the last three years, so we doubt that explains the falling share price. There doesn't seem to be any clear correlation between the fundamental business metrics and the share price. That could mean that the stock was previously overrated, or it could spell opportunity now.

However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 6% per annum loss investors have suffered over the last half decade. We would want clear information suggesting the company will grow, before taking the view that the share price will stabilize.
