As every investor would know, not every swing hits the sweet spot. But really big losses can really drag down an overall portfolio. So consider, for a moment, the misfortune of Cable One, Inc. (NYSE:CABO) investors who have held the stock for three years as it declined a whopping 82%. That'd be enough to cause even the strongest minds some disquiet. And the ride hasn't got any smoother in recent times over the last year, with the price 36% lower in that time. Shareholders have had an even rougher run lately, with the share price down 27% in the last 90 days. 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. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

While the stock has risen 9.1% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Cable One saw its EPS decline at a compound rate of 62% per year, over the last three years. In comparison the 44% compound annual share price decline isn't as bad as the EPS drop-off. This suggests that the market retains some optimism around long term earnings stability, despite past EPS declines. This positive sentiment is also reflected in the generous P/E ratio of 106.26.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider. This free interactive report on Cable One's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

A Different Perspective

Investors in Cable One had a tough year, with a total loss of 33% (including dividends), against a market gain of about 10%. 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 13% 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. Consider for instance, the ever-present spectre of investment risk.
