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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into American International Group Inc (NYSE: AIG)? Today, we examine the outcome of a ten year investment into the stock back in 2009.

Start date: 12/07/2009
$10,000

12/07/2009
$22,834

12/04/2019
End date: 12/04/2019
Start price/share: $30.17
End price/share: $51.11
Starting shares: 331.46
Ending shares: 446.92
Dividends reinvested/share: $15.01
Total return: 128.42%
Average annual return: 8.61%
Starting investment: $10,000.00
Ending investment: $22,834.94

As shown above, the ten year investment result worked out well, with an annualized rate of return of 8.61%. This would have turned a $10K investment made 10 years ago into $22,834.94 today (as of 12/04/2019). On a total return basis, that’s a result of 128.42% (something to think about: how might AIG shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American International Group Inc paid investors a total of $15.01/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 1.28/share, we calculate that AIG has a current yield of approximately 2.50%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.28 against the original $30.17/share purchase price. This works out to a yield on cost of 8.29%.
