The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Skyline Champion Corporation (NYSE:SKY) share price has soared 261% in the last half decade. Most would be very happy with that. On top of that, the share price is up 26% in about a quarter. But this could be related to the strong market, which is up 13% in the last three months.

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.

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. 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.

During the last half decade, Skyline Champion became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. We can see that the Skyline Champion share price is up 69% in the last three years. During the same period, EPS grew by 65% each year. This EPS growth is higher than the 19% average annual increase in the share price over the same three years. So you might conclude the market is a little more cautious about the stock, these days.

A Different Perspective

Skyline Champion provided a TSR of 3.3% over the last twelve months. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 29% over five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
