“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 NRG Energy Inc (NYSE: NRG)? Today, we examine the outcome of a five year investment into the stock back in 2018.

Start date: 06/18/2018
$10,000

06/18/2018
  $11,874

06/15/2023
End date: 06/15/2023
Start price/share: $32.98
End price/share: $34.37
Starting shares: 303.21
Ending shares: 345.47
Dividends reinvested/share: $4.84
Total return: 18.74%
Average annual return: 3.50%
Starting investment: $10,000.00
Ending investment: $11,874.62

As we can see, the five year investment result worked out as follows, with an annualized rate of return of 3.50%. This would have turned a $10K investment made 5 years ago into $11,874.62 today (as of 06/15/2023). On a total return basis, that’s a result of 18.74% (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.]

Notice that NRG Energy Inc paid investors a total of $4.84/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 1.51/share, we calculate that NRG has a current yield of approximately 4.39%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.51 against the original $32.98/share purchase price. This works out to a yield on cost of 13.31%.
