Sonoco Products (NYSE:SON) adds US$198m to market cap in the past 7 days, though investors from three years ago are still down 4.7%

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Sonoco Products Company (NYSE:SON) shareholders, since the share price is down 14% in the last three years, falling well short of the market return of around 25%.

On a more encouraging note the company has added US$198m 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.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Sonoco Products 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 it's worth looking at other metrics to try to understand the share price move.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. It's good to see that Sonoco Products has increased 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 know that Sonoco Products has improved its bottom line over the last three years, but what does the future have in store? It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

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 Sonoco Products the TSR over the last 3 years was -4.7%, 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

While the broader market gained around 35% in the last year, Sonoco Products shareholders lost 2.6% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 0.4%, 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. It's always interesting to track share price performance over the longer term. But to understand Sonoco Products better, we need to consider many other factors.
