The total return for Instalco (STO:INSTAL) investors has risen faster than earnings growth over the last five years

It might be of some concern to shareholders to see the Instalco AB (publ) (STO:INSTAL) share price down 13% in the last month. But that doesn't change the fact that shareholders have received really good returns over the last five years. It's fair to say most would be happy with 144% the gain in that time. To some, the recent pullback wouldn't be surprising after such a fast rise. Ultimately business performance will determine whether the stock price continues the positive long term trend. Unfortunately not all shareholders will have held it for the long term, so spare a thought for those caught in the 30% decline over the last twelve months.

While the stock has fallen 8.0% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

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, Instalco managed to grow its earnings per share at 18% a year. This EPS growth is reasonably close to the 20% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

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.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Instalco, it has a TSR of 161% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 8.6% in the last year, Instalco shareholders lost 30% (even including dividends). 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. Longer term investors wouldn't be so upset, since they would have made 21%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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 risks, for instance. Every company has them, and we've spotted 3 warning signs for Instalco you should know about.
