Sanlorenzo (BIT:SL) jumps 6.1% this week, though earnings growth is still tracking behind five-year shareholder returns

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For instance, the price of Sanlorenzo S.p.A. (BIT:SL) stock is up an impressive 114% over the last five years. In the last week the share price is up 6.1%.

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, Sanlorenzo achieved compound earnings per share (EPS) growth of 27% per year. This EPS growth is higher than the 16% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Sanlorenzo's TSR for the last 5 years was 130%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Sanlorenzo shareholders are down 19% for the year (even including dividends), but the market itself is up 21%. 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. On the bright side, long term shareholders have made money, with a gain of 18% per year over half a decade. 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.
