“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 DTE Energy Co (NYSE: DTE)? Today, we examine the outcome of a five year investment into the stock back in 2019.

Start date: 04/24/2019


End date: 04/23/2024
Start price/share: $105.57
End price/share: $110.12
Starting shares: 94.72
Ending shares: 111.86
Dividends reinvested/share: $18.04
Total return: 23.18%
Average annual return: 4.26%
Starting investment: $10,000.00
Ending investment: $12,320.78

As we can see, the five year investment result worked out as follows, with an annualized rate of return of 4.26%. This would have turned a $10K investment made 5 years ago into $12,320.78 today (as of 04/23/2024). On a total return basis, that’s a result of 23.18% (something to think about: how might DTE shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that DTE Energy Co paid investors a total of $18.04/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 4.08/share, we calculate that DTE has a current yield of approximately 3.71%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.08 against the original $105.57/share purchase price. This works out to a yield on cost of 3.51%.
