Statistically speaking, long term investing is a profitable endeavour. But along the way some stocks are going to perform badly. Zooming in on an example, the Humm Group Limited (ASX:HUM) share price dropped 61% in the last half decade. That's an unpleasant experience for long term holders.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Over five years Humm Group's earnings per share dropped significantly, falling to a loss, with the share price also lower. This was, in part, due to extraordinary items impacting earnings. At present it's hard to make valid comparisons between EPS and the share price. However, we can say we'd expect to see a falling share price in this scenario.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. It might be well worthwhile taking a look at our freereport on Humm Group's earnings, revenue and cash flow.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Humm Group, it has a TSR of -54% 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

Investors in Humm Group had a tough year, with a total loss of 15% (including dividends), against a market gain of about 6.5%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 9% over the last half decade. 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.
