“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 Micron Technology Inc. (NASD: MU)? Today, we examine the outcome of a five year investment into the stock back in 2018.

Start date: 06/01/2018
$10,000

06/01/2018
  $11,751

05/31/2023
End date: 05/31/2023
Start price/share: $58.74
End price/share: $68.20
Starting shares: 170.24
Ending shares: 172.34
Dividends reinvested/share: $0.76
Total return: 17.53%
Average annual return: 3.28%
Starting investment: $10,000.00
Ending investment: $11,751.17

The above analysis shows the five year investment result worked out as follows, with an annualized rate of return of 3.28%. This would have turned a $10K investment made 5 years ago into $11,751.17 today (as of 05/31/2023). On a total return basis, that’s a result of 17.53% (something to think about: how might MU shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Micron Technology Inc. paid investors a total of $0.76/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 .46/share, we calculate that MU has a current yield of approximately 0.67%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .46 against the original $58.74/share purchase price. This works out to a yield on cost of 1.14%.
