Should Quest Diagnostics Be Disappointed With Their 64% Profit?

Simply Wall St

Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, the Quest Diagnostics Incorporated (NYSE:DGX) share price is up 64% in the last 5 years, clearly besting than the market return of around 40% (ignoring dividends).

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Over half a decade, Quest Diagnostics managed to grow its earnings per share at 0.2% a year. This EPS growth is slower than the share price growth of 10% per year, over the same period. So it’s fair to assume the market has a higher opinion of the business than it did five years ago. That’s not necessarily surprising considering the five-year track record of earnings growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Quest Diagnostics, it has a TSR of 82% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Investors in Quest Diagnostics had a tough year, with a total loss of 13% (including dividends), against a market gain of about 5.3%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 13% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
