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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a two-decade holding period for an investor who was considering DTE Energy Co (NYSE: DTE) back in 2001, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 04/20/2001
$10,000

04/20/2001
$78,987

04/19/2021
End date: 04/19/2021
Start price/share: $41.75
End price/share: $139.70
Starting shares: 239.52
Ending shares: 565.14
Dividends reinvested/share: $52.32
Total return: 689.50%
Average annual return: 10.88%
Starting investment: $10,000.00
Ending investment: $78,987.05

As shown above, the two-decade investment result worked out quite well, with an annualized rate of return of 10.88%. This would have turned a $10K investment made 20 years ago into $78,987.05 today (as of 04/19/2021). On a total return basis, that’s a result of 689.50% (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.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 20 years, DTE Energy Co has paid $52.32/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 4.34/share, we calculate that DTE has a current yield of approximately 3.11%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.34 against the original $41.75/share purchase price. This works out to a yield on cost of 7.45%.

Here’s one more great investment quote before you go:
“I learned early that there is nothing new in Wall Street. There can’t be because speculation is as old as the hills. Whatever happens in the stock market today has happened before and will happen again. I’ve never forgotten that.” — Jesse Livermore
