In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term PPG Industries, Inc. (NYSE:PPG) shareholders have had that experience, with the share price dropping 13% in three years, versus a market return of about 20%.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

View 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.

PPG Industries saw its EPS decline at a compound rate of 1.2% per year, over the last three years. The share price decline of 5% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

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.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. We note that for PPG Industries the TSR over the last 3 years was -8.0%, 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

PPG Industries shareholders gained a total return of 1.4% during the year. Unfortunately this falls short of the market return. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 4% over five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
