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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five 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 five year investment into the stock back in 2017.

Start date: 04/28/2017


End date: 04/27/2022
Start price/share: $60.91
End price/share: $59.12
Starting shares: 164.18
Ending shares: 188.27
Dividends reinvested/share: $6.40
Total return: 11.31%
Average annual return: 2.17%
Starting investment: $10,000.00
Ending investment: $11,133.12

As shown above, the five year investment result worked out as follows, with an annualized rate of return of 2.17%. This would have turned a $10K investment made 5 years ago into $11,133.12 today (as of 04/27/2022). On a total return basis, that’s a result of 11.31% (something to think about: how might AIG shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American International Group Inc paid investors a total of $6.40/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 1.28/share, we calculate that AIG has a current yield of approximately 2.17%. 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 $60.91/share purchase price. This works out to a yield on cost of 3.56%.
