“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into American International Group Inc (NYSE: AIG) back in 2019: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 09/26/2019
$10,000

09/26/2019
  $14,922

09/25/2024
End date: 09/25/2024
Start price/share: $55.88
End price/share: $73.02
Starting shares: 178.95
Ending shares: 204.33
Dividends reinvested/share: $6.72
Total return: 49.20%
Average annual return: 8.33%
Starting investment: $10,000.00
Ending investment: $14,922.41

As shown above, the five year investment result worked out well, with an annualized rate of return of 8.33%. This would have turned a $10K investment made 5 years ago into $14,922.41 today (as of 09/25/2024). On a total return basis, that’s a result of 49.20% (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 $6.72/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 1.6/share, we calculate that AIG has a current yield of approximately 2.19%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.6 against the original $55.88/share purchase price. This works out to a yield on cost of 3.92%.
