Hamamatsu Photonics K.K (TSE:6965) shareholders have endured a 39% loss from investing in the stock three years ago

Hamamatsu Photonics K.K. (TSE:6965) shareholders should be happy to see the share price up 15% in the last month. But that doesn't help the fact that the three year return is less impressive. After all, the share price is down 42% in the last three years, significantly under-performing the market.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

View our latest analysis for Hamamatsu Photonics K.K

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Although the share price is down over three years, Hamamatsu Photonics K.K actually managed to grow EPS by 11% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. 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.

The modest 1.9% dividend yield is unlikely to be guiding the market view of the stock. Revenue is actually up 9.0% over the three years, so the share price drop doesn't seem to hinge on revenue, either. It's probably worth investigating Hamamatsu Photonics K.K further; while we may be missing something on this analysis, there might also be an opportunity.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Hamamatsu Photonics K.K, it has a TSR of -39% for the last 3 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 18% in the last year, Hamamatsu Photonics K.K shareholders lost 29% (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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 0.4% 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
