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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a decade-long holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Phillips 66 (NYSE: PSX) back in 2012: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 08/17/2012
$10,000

08/17/2012
  $28,892

08/16/2022
End date: 08/16/2022
Start price/share: $42.77
End price/share: $89.36
Starting shares: 233.81
Ending shares: 323.33
Dividends reinvested/share: $26.54
Total return: 188.93%
Average annual return: 11.19%
Starting investment: $10,000.00
Ending investment: $28,892.39

As we can see, the decade-long investment result worked out quite well, with an annualized rate of return of 11.19%. This would have turned a $10K investment made 10 years ago into $28,892.39 today (as of 08/16/2022). On a total return basis, that’s a result of 188.93% (something to think about: how might PSX shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Phillips 66 paid investors a total of $26.54/share in dividends over the 10 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 3.88/share, we calculate that PSX has a current yield of approximately 4.34%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.88 against the original $42.77/share purchase price. This works out to a yield on cost of 10.15%.
