“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a five year holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 5 years to 2019, investors considering an investment into shares of Aon plc (NYSE: AON) may have been pondering this very question and thinking about their potential investment result over a full five year time horizon. Here’s how that would have worked out.

Start date: 08/13/2019
$10,000

08/13/2019
  $17,938

08/12/2024
End date: 08/12/2024
Start price/share: $190.98
End price/share: $328.86
Starting shares: 52.36
Ending shares: 54.56
Dividends reinvested/share: $10.77
Total return: 79.41%
Average annual return: 12.39%
Starting investment: $10,000.00
Ending investment: $17,938.14

As we can see, the five year investment result worked out quite well, with an annualized rate of return of 12.39%. This would have turned a $10K investment made 5 years ago into $17,938.14 today (as of 08/12/2024). On a total return basis, that’s a result of 79.41% (something to think about: how might AON shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Aon plc paid investors a total of $10.77/share in dividends over the 5 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 2.7/share, we calculate that AON has a current yield of approximately 0.82%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.7 against the original $190.98/share purchase price. This works out to a yield on cost of 0.43%.
