Buying shares in the best businesses can build meaningful wealth for you and your family. And highest quality companies can see their share prices grow by huge amounts. Don't believe it? Then look at the SPX Technologies, Inc. (NYSE:SPXC) share price. It's 323% higher than it was five years ago. This just goes to show the value creation that some businesses can achieve. On top of that, the share price is up 26% in about a quarter. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report.

The past week has proven to be lucrative for SPX Technologies investors, so let's see if fundamentals drove the company's five-year performance.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, SPX Technologies managed to grow its earnings per share at 17% a year. This EPS growth is slower than the share price growth of 33% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

A Different Perspective

It's nice to see that SPX Technologies shareholders have received a total shareholder return of 82% over the last year. That gain is better than the annual TSR over five years, which is 33%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
