“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 2017, investors considering an investment into shares of Ameren Corp (NYSE: AEE) 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: 07/28/2017


End date: 07/27/2022
Start price/share: $56.16
End price/share: $89.39
Starting shares: 178.06
Ending shares: 204.00
Dividends reinvested/share: $10.05
Total return: 82.36%
Average annual return: 12.77%
Starting investment: $10,000.00
Ending investment: $18,237.61

As shown above, the five year investment result worked out quite well, with an annualized rate of return of 12.77%. This would have turned a $10K investment made 5 years ago into $18,237.61 today (as of 07/27/2022). On a total return basis, that’s a result of 82.36% (something to think about: how might AEE shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Ameren Corp paid investors a total of $10.05/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 2.36/share, we calculate that AEE has a current yield of approximately 2.64%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.36 against the original $56.16/share purchase price. This works out to a yield on cost of 4.70%.
