Shareholders in Renishaw (LON:RSW) are in the red if they invested three years ago

Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Renishaw plc (LON:RSW) shareholders have had that experience, with the share price dropping 40% in three years, versus a market decline of about 12%. Furthermore, it's down 12% in about a quarter. That's not much fun for holders.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Renishaw saw its EPS decline at a compound rate of 4.5% per year, over the last three years. This reduction in EPS is slower than the 15% annual reduction in the share price. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Renishaw, it has a TSR of -35% for the last 3 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Renishaw shareholders gained a total return of 0.9% during the year. But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 2% endured over half a decade. It could well be that the business is stabilizing. 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.
