Investors can approximate the average market return by buying an index fund. But if you buy individual stocks, you can do both better or worse than that. Investors in Spark New Zealand Limited (NZSE:SPK) have tasted that bitter downside in the last year, as the share price dropped 41%. That contrasts poorly with the market return of 14%. Notably, shareholders had a tough run over the longer term, too, with a drop of 36% in the last three years. The falls have accelerated recently, with the share price down 30% in the last three months.

After losing 5.8% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

Unfortunately Spark New Zealand reported an EPS drop of 71% for the last year. The share price fall of 41% isn't as bad as the reduction in earnings per share. So despite the weak per-share profits, some investors are probably relieved the situation wasn't more difficult.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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 Spark New Zealand, it has a TSR of -36% for the last 1 year. 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 14% in the last year, Spark New Zealand shareholders lost 36% (even including dividends). 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 1.4% 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.
