Oxford Metrics (LON:OMG) adds UK£7.6m to market cap in the past 7 days, though investors from three years ago are still down 39%

Oxford Metrics plc (LON:OMG) shareholders should be happy to see the share price up 17% in the last week. But that doesn't help the fact that the three year return is less impressive. After all, the share price is down 45% in the last three years, significantly under-performing the market.

On a more encouraging note the company has added UK£7.6m to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

Over the three years that the share price declined, Oxford Metrics' earnings per share (EPS) dropped significantly, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

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. We note that for Oxford Metrics the TSR over the last 3 years was -39%, 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

Oxford Metrics shareholders are down 19% for the year (even including dividends), but the market itself is up 17%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 6% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. It's always interesting to track share price performance over the longer term. But to understand Oxford Metrics better, we need to consider many other factors. Even so, be aware that Oxford Metrics is showing 2 warning signs in our investment analysis , and 1 of those shouldn't be ignored...
