“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

A key lesson we can learn from Warren Buffett, is about how to think about a potential stock investment in the context of a long-term time horizon. Every investor in a stock has a choice: bite our fingernails over the short-term ups and downs that are inevitable with the stock market, or, zero in on stocks we are comfortable to simply buy and hold for the long haul — maybe even a five year holding period. Heck, investors can even choose to completely ignore the stock market’s short-run quotations and instead go into their initial investment planning to hold on for years and years regardless of the fluctuations in price that might occur next.

Today, we examine what would have happened over a five year holding period, had you decided back in 2016 to buy shares of NRG Energy Inc (NYSE: NRG) and simply hold through to today.

Start date: 08/16/2016
$10,000

08/16/2016
$38,288

08/13/2021
End date: 08/13/2021
Start price/share: $12.30
End price/share: $43.65
Starting shares: 813.01
Ending shares: 877.11
Dividends reinvested/share: $2.57
Total return: 282.86%
Average annual return: 30.84%
Starting investment: $10,000.00
Ending investment: $38,288.03

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 30.84%. This would have turned a $10K investment made 5 years ago into $38,288.03 today (as of 08/13/2021). On a total return basis, that’s a result of 282.86% (something to think about: how might NRG shares perform over the next 5 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 5 years, NRG Energy Inc has paid $2.57/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 1.3/share, we calculate that NRG has a current yield of approximately 2.98%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.3 against the original $12.30/share purchase price. This works out to a yield on cost of 24.23%.
