While shareholders of XP Power (LON:XPP) are in the red over the last three years, underlying earnings have actually grown

It's nice to see the XP Power Limited (LON:XPP) share price up 13% in a week. But that doesn't change the fact that the returns over the last three years have been stomach churning. In that time the share price has melted like a snowball in the desert, down 77%. So it's about time shareholders saw some gains. Only time will tell if the company can sustain the turnaround.

While the stock has risen 13% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

XP Power became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. So given the share price is down it's worth checking some other metrics too.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. We like that XP Power has actually grown its revenue over the last three years. If the company can keep growing revenue, there may be an opportunity for investors. You might have to dig deeper to understand the recent share price weakness.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business. This free report showing analyst forecasts should help you form a view on XP Power

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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 XP Power, it has a TSR of -75% 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

Investors in XP Power had a tough year, with a total loss of 31% (including dividends), against a market gain of about 9.5%. 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 9% per year over five years. 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.
