Investing in stocks inevitably means buying into some companies that perform poorly. Long term WPP plc (LON:WPP) shareholders know that all too well, since the share price is down considerably over three years. Regrettably, they have had to cope with a 66% drop in the share price over that period. And over the last year the share price fell 57%, so we doubt many shareholders are delighted. Shareholders have had an even rougher run lately, with the share price down 12% in the last 90 days.

While the stock has risen 3.8% in the past week but long term shareholders are still in the red, let’s see what the fundamentals can tell us.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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.

During the three years that the share price fell, WPP’s earnings per share (EPS) dropped by 14% each year. The share price decline of 30% is actually steeper than the EPS slippage. So it seems the market was too confident about the business, in the past. The less favorable sentiment is reflected in its current P/E ratio of 9.08.

It’s probably worth noting we’ve seen significant insider buying in the last quarter, which we consider a positive. That said, we think earnings and revenue growth trends are even more important factors to consider. This free interactive report on WPP’s earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It’s fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for WPP the TSR over the last 3 years was -60%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

Investors in WPP had a tough year, with a total loss of 54% (including dividends), against a market gain of about 25%. 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 8% 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. 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.
