Investors in NewMarket (NYSE:NEU) have seen strong returns of 102% over the past three years

By buying an index fund, you can roughly match the market return with ease. But if you choose individual stocks with prowess, you can make superior returns. Just take a look at NewMarket Corporation (NYSE:NEU), which is up 90%, over three years, soundly beating the market return of 37% (not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 20%, including dividends.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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 NewMarket the TSR over the last 3 years was 102%, 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

In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
