For many investors, the main point of stock picking is to generate higher returns than the overall market. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Spirax Group plc (LON:SPX) shareholders have had that experience, with the share price dropping 36% in three years, versus a market return of about 29%. And over the last year the share price fell 29%, so we doubt many shareholders are delighted. Unfortunately the share price momentum is still quite negative, with prices down 10% in thirty days.

After losing 4.5% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the three years that the share price fell, Spirax Group's earnings per share (EPS) dropped by 2.3% each year. This reduction in EPS is slower than the 14% annual reduction in the share price. So it seems the market was too confident about the business, in the past.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. It might be well worthwhile taking a look at our freereport on Spirax 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). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Spirax Group, it has a TSR of -33% for the last 3 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market gained around 16% in the last year, Spirax Group shareholders lost 28% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 1.2% 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.
