Many investors define successful investing as beating the market average over the long term. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term Bodycote plc (LON:BOY) shareholders, since the share price is down 30% in the last three years, falling well short of the market return of around 17%. Shareholders have had an even rougher run lately, with the share price down 17% in the last 90 days.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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.

During the unfortunate three years of share price decline, Bodycote actually saw its earnings per share (EPS) improve by 24% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

We note that, in three years, revenue has actually grown at a 11% annual rate, so that doesn't seem to be a reason to sell shares. It's probably worth investigating Bodycote further; while we may be missing something on this analysis, there might also be an opportunity.

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. This free report showing analyst forecasts should help you form a view on Bodycote

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 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Bodycote the TSR over the last 3 years was -22%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in Bodycote had a tough year, with a total loss of 2.4% (including dividends), against a market gain of about 14%. 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 0.7% 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. Take risks, for example - Bodycote has 2 warning signs we think you should be aware of.
