“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 twenty year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Ameren Corp (NYSE: AEE) back in 2004: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 11/26/2004
$10,000

11/26/2004
  $43,365

11/22/2024
End date: 11/22/2024
Start price/share: $49.75
End price/share: $93.81
Starting shares: 201.01
Ending shares: 462.10
Dividends reinvested/share: $40.25
Total return: 333.50%
Average annual return: 7.61%
Starting investment: $10,000.00
Ending investment: $43,365.05

The above analysis shows the twenty year investment result worked out well, with an annualized rate of return of 7.61%. This would have turned a $10K investment made 20 years ago into $43,365.05 today (as of 11/22/2024). On a total return basis, that’s a result of 333.50% (something to think about: how might AEE shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Ameren Corp paid investors a total of $40.25/share in dividends over the 20 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 2.68/share, we calculate that AEE has a current yield of approximately 2.86%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.68 against the original $49.75/share purchase price. This works out to a yield on cost of 5.75%.

Here’s one more great investment quote before you go:
