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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a twenty year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in NRG Energy Inc (NYSE: NRG) back in 2004, holding through to today.

Start date: 08/16/2004
$10,000

08/16/2004
  $78,092

08/13/2024
End date: 08/13/2024
Start price/share: $13.72
End price/share: $81.86
Starting shares: 728.86
Ending shares: 954.59
Dividends reinvested/share: $8.98
Total return: 681.43%
Average annual return: 10.82%
Starting investment: $10,000.00
Ending investment: $78,092.15

As we can see, the twenty year investment result worked out quite well, with an annualized rate of return of 10.82%. This would have turned a $10K investment made 20 years ago into $78,092.15 today (as of 08/13/2024). On a total return basis, that’s a result of 681.43% (something to think about: how might NRG shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Many investors out there refuse to own any stock that lacks a dividend; in the case of NRG Energy Inc, investors have received $8.98/share in dividends these past 20 years examined in the exercise above. This means total return was driven not just by share price, but also by the dividends received (and what the investor did with those dividends). For this exercise, what we’ve done with the dividends is to assume they are reinvestted — i.e. used to purchase additional shares (the calculations use closing price on ex-date).

Based upon the most recent annualized dividend rate of 1.63/share, we calculate that NRG has a current yield of approximately 1.99%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.63 against the original $13.72/share purchase price. This works out to a yield on cost of 14.50%.

Another great investment quote to think about:
“All you need for a lifetime of successful investing is a few big winners, and the pluses from those will overwhelm the minuses from the stocks that don’t work out.” — Peter Lynch
