PPG Industries (NYSE:PPG) investors are sitting on a loss of 24% if they invested three years ago

As an investor its worth striving to ensure your overall portfolio beats the market average. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term PPG Industries, Inc. (NYSE:PPG) shareholders, since the share price is down 28% in the last three years, falling well short of the market return of around 30%. Furthermore, it's down 11% in about a quarter. That's not much fun for holders.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

Check out our latest analysis for PPG Industries

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 the unfortunate three years of share price decline, PPG Industries actually saw its earnings per share (EPS) improve by 2.3% per year. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

It looks to us like the market was probably too optimistic around growth three years ago. However, taking a look at other business metrics might shed a bit more light on the share price action.

With revenue flat over three years, it seems unlikely that the share price is reflecting the top line. We're not entirely sure why the share price is dropped, but it does seem likely investors have become less optimistic about the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, PPG Industries' TSR for the last 3 years was -24%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 25% in the last year, PPG Industries shareholders lost 17% (even including dividends). 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. Longer term investors wouldn't be so upset, since they would have made 0.2%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
