The five-year loss for Sunpower Group (SGX:5GD) shareholders likely driven by its shrinking earnings

Sunpower Group Ltd. (SGX:5GD) shareholders should be happy to see the share price up 10% in the last week. But if you look at the last five years the returns have not been good. You would have done a lot better buying an index fund, since the stock has dropped 50% in that half decade.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

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

Sunpower Group became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

In contrast to the share price, revenue has actually increased by 7.3% a year in the five year period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

A Dividend Lost

It's important to keep in mind that we've been talking about the share price returns, which don't include dividends, while the total shareholder return does. Many would argue the TSR gives a more complete picture of the value a stock brings to its holders. Over the last 5 years, Sunpower Group generated a TSR of -32%, which is, of course, better than the share price return. Although the company had to cut dividends, it has paid cash to shareholders in the past.

A Different Perspective

Sunpower Group shareholders are up 18% for the year. Unfortunately this falls short of the market return. But at least that's still a gain! Over five years the TSR has been a reduction of 6% per year, over five years. So this might be a sign the business has turned its fortunes around. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
