“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a decade-long holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Quest Diagnostics, Inc. (NYSE: DGX) back in 2010, holding through to today.

Start date: 12/30/2010
$10,000

12/30/2010
$26,283

12/29/2020
End date: 12/29/2020
Start price/share: $54.18
End price/share: $118.40
Starting shares: 184.57
Ending shares: 221.90
Dividends reinvested/share: $14.70
Total return: 162.73%
Average annual return: 10.14%
Starting investment: $10,000.00
Ending investment: $26,283.34

As shown above, the decade-long investment result worked out quite well, with an annualized rate of return of 10.14%. This would have turned a $10K investment made 10 years ago into $26,283.34 today (as of 12/29/2020). On a total return basis, that’s a result of 162.73% (something to think about: how might DGX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Beyond share price change, another component of DGX’s total return these past 10 years has been the payment by Quest Diagnostics, Inc. of $14.70/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 2.24/share, we calculate that DGX has a current yield of approximately 1.89%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.24 against the original $54.18/share purchase price. This works out to a yield on cost of 3.49%.
