By buying an index fund, investors can approximate the average market return. But if you buy good businesses at attractive prices, your portfolio returns could exceed the average market return. For example, the BWX Technologies, Inc. (NYSE:BWXT) share price is up 84% in the last three years, clearly besting the market return of around 17% (not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 39%, including dividends.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

During three years of share price growth, BWX Technologies achieved compound earnings per share growth of 1.4% per year. This EPS growth is lower than the 23% average annual increase in the share price. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. It's not unusual to see the market 're-rate' a stock, after a few years of growth.

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. In the case of BWX Technologies, it has a TSR of 92% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that BWX Technologies shareholders have received a total shareholder return of 39% over the last year. Of course, that includes the dividend. That's better than the annualised return of 14% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
