Investors in Comcast (NASDAQ:CMCSA) have unfortunately lost 24% over the last three years

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. Unfortunately, that's been the case for longer term Comcast Corporation (NASDAQ:CMCSA) shareholders, since the share price is down 30% in the last three years, falling well short of the market return of around 23%.

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the unfortunate three years of share price decline, Comcast actually saw its earnings per share (EPS) improve by 13% per year. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Alternatively, growth expectations may have been unreasonable in the past.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The company has kept revenue pretty healthy over the last three years, so we doubt that explains the falling share price. 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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Comcast's 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

Comcast shareholders are down 11% for the year (even including dividends), but the market itself is up 27%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 0.5% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
