Sasol's (JSE:SOL) earnings trajectory could turn positive as the stock increases 7.8% this past week

Generally speaking long term investing is the way to go. But unfortunately, some companies simply don't succeed. Zooming in on an example, the Sasol Limited (JSE:SOL) share price dropped 68% in the last half decade. That is extremely sub-optimal, to say the least. And we doubt long term believers are the only worried holders, since the stock price has declined 39% over the last twelve months. The falls have accelerated recently, with the share price down 21% in the last three months.

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. 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, Sasol moved from a loss to profitability. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

The steady dividend doesn't really explain why the share price is down. While it's not completely obvious why the share price is down, a closer look at the company's history might help explain it.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. You can see what analysts are predicting for Sasol in this interactive graph of future profit estimates.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Sasol, it has a TSR of -64% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 2.3% in the last year, Sasol shareholders lost 35% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 10% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality 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.
