Okeanis Eco Tankers (OB:OET) jumps 8.6% this week, though earnings growth is still tracking behind five-year shareholder returns

Long term investing can be life changing when you buy and hold the truly great businesses. And we've seen some truly amazing gains over the years. For example, the Okeanis Eco Tankers Corp. (OB:OET) share price is up a whopping 317% in the last half decade, a handsome return for long term holders. And this is just one example of the epic gains achieved by some long term investors. It's even up 8.6% in the last week.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

During five years of share price growth, Okeanis Eco Tankers achieved compound earnings per share (EPS) growth of 9.2% per year. This EPS growth is lower than the 33% average annual increase in the share price. 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.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Okeanis Eco Tankers, it has a TSR of 664% 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

Okeanis Eco Tankers shareholders are down 20% for the year (even including dividends), but the market itself is up 17%. 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 50%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
