Oxford Instruments (LON:OXIG) jumps 5.5% this week, though earnings growth is still tracking behind five-year shareholder returns

It hasn't been the best quarter for Oxford Instruments plc (LON:OXIG) shareholders, since the share price has fallen 12% in that time. But at least the stock is up over the last five years. In that time, it is up 72%, which isn't bad, but is below the market return of 78%.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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.

During five years of share price growth, Oxford Instruments achieved compound earnings per share (EPS) growth of 8.9% per year. This EPS growth is lower than the 11% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

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 Oxford Instruments, it has a TSR of 78% for the last 5 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

Investors in Oxford Instruments had a tough year, with a total loss of 6.7% (including dividends), against a market gain of about 14%. 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. On the bright side, long term shareholders have made money, with a gain of 12% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
