The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. For example, the Steel Dynamics, Inc. (NASDAQ:STLD) share price has soared 232% in the last half decade. Most would be very happy with that. On top of that, the share price is up 11% in about a quarter. But this move may well have been assisted by the reasonably buoyant market (up 12% in 90 days).

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, Steel Dynamics managed to grow its earnings per share at 23% a year. So the EPS growth rate is rather close to the annualized share price gain of 27% per year. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Steel Dynamics the TSR over the last 5 years was 274%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Steel Dynamics shareholders are down 0.6% 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. Longer term investors wouldn't be so upset, since they would have made 30%, 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. For instance, we've identified 2 warning signs for Steel Dynamics (1 doesn't sit too well with us) that you should be aware of.
