“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty 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 twenty year investment into the stock back in 2003.
| Start date: | 02/03/2003 |

| End date: | 02/02/2023 | ||||
| Start price/share: | $36.17 | ||||
| End price/share: | $114.71 | ||||
| Starting shares: | 276.47 | ||||
| Ending shares: | 632.53 | ||||
| Dividends reinvested/share: | $47.70 | ||||
| Total return: | 625.58% | ||||
| Average annual return: | 10.41% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $72,550.35 | ||||
As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 10.41%. This would have turned a $10K investment made 20 years ago into $72,550.35 today (as of 02/02/2023). On a total return basis, that’s a result of 625.58% (something to think about: how might DTE shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that DTE Energy Co paid investors a total of $47.70/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 3.81/share, we calculate that DTE has a current yield of approximately 3.32%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.81 against the original $36.17/share purchase price. This works out to a yield on cost of 9.18%.
Another great investment quote to think about:
“Wide diversification is only required when investors do not understand what they are doing.” — Warren Buffett
