NOS S.G.P.S (ELI:NOS) shareholders have endured a 16% loss from investing in the stock five years ago

Ideally, your overall portfolio should beat the market average. But even the best stock picker will only win with some selections. So we wouldn't blame long term NOS, S.G.P.S., S.A. (ELI:NOS) shareholders for doubting their decision to hold, with the stock down 39% over a half decade.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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

While the share price declined over five years, NOS S.G.P.S actually managed to increase EPS by an average of 7.7% per year. So it doesn't seem like EPS is a great guide to understanding how the market is valuing the stock. Alternatively, growth expectations may have been unreasonable in the past.

Due to the lack of correlation between the EPS growth and the falling share price, it's worth taking a look at other metrics to try to understand the share price movement.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. It's not immediately clear to us why the stock price is down but further research might provide some answers.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of NOS S.G.P.S, it has a TSR of -16% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that NOS S.G.P.S has rewarded shareholders with a total shareholder return of 27% in the last twelve months. And that does include the dividend. That certainly beats the loss of about 3% per year over the last half decade. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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.
