Buying shares in the best businesses can build meaningful wealth for you and your family. While not every stock performs well, when investors win, they can win big. To wit, the Universal Technical Institute, Inc. (NYSE:UTI) share price has soared 360% over five years. And this is just one example of the epic gains achieved by some long term investors. We note the stock price is up 6.1% in the last seven days.

Since the stock has added US$83m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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).

During the last half decade, Universal Technical Institute 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. Indeed, the Universal Technical Institute share price has gained 180% in three years. Meanwhile, EPS is up 32% per year. This EPS growth is lower than the 41% average annual increase in the share price over three years. So one can reasonably conclude the market is more enthusiastic about the stock than it was three years ago.

A Different Perspective

It's nice to see that Universal Technical Institute shareholders have received a total shareholder return of 79% over the last year. That's better than the annualised return of 36% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
