As every investor would know, not every swing hits the sweet spot. But really bad investments should be rare. So consider, for a moment, the misfortune of Altice USA, Inc. (NYSE:ATUS) investors who have held the stock for three years as it declined a whopping 84%. That would be a disturbing experience. The more recent news is of little comfort, with the share price down 75% in a year. Shareholders have had an even rougher run lately, with the share price down 60% 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. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

After losing 19% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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).

Although the share price is down over three years, Altice USA actually managed to grow EPS by 40% 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.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The company has kept revenue pretty healthy over the last three years, so we doubt that explains the falling share price. We're not entirely sure why the share price is dropped, but it does seem likely investors have become less optimistic about the business.

The company's revenue and earnings (over time) are depicted in the image below (click to see the exact numbers).

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. This free report showing analyst forecasts should help you form a view on Altice USA

A Different Perspective

We regret to report that Altice USA shareholders are down 75% for the year. Unfortunately, that's worse than the broader market decline of 21%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 12% 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. It's always interesting to track share price performance over the longer term. But to understand Altice USA better, we need to consider many other factors. Like risks, for instance. Every company has them, and we've spotted 6 warning signs for Altice USA (of which 2 are concerning!) you should know about.
