“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty 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 twenty year investment into the stock back in 2001.

Start date: 10/19/2001
$10,000

10/19/2001
$32,396

10/18/2021
End date: 10/18/2021
Start price/share: $20.80
End price/share: $67.26
Starting shares: 480.77
Ending shares: 481.45
Dividends reinvested/share: $0.10
Total return: 223.82%
Average annual return: 6.05%
Starting investment: $10,000.00
Ending investment: $32,396.12

The above analysis shows the twenty year investment result worked out well, with an annualized rate of return of 6.05%. This would have turned a $10K investment made 20 years ago into $32,396.12 today (as of 10/18/2021). On a total return basis, that’s a result of 223.82% (something to think about: how might MU shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Beyond share price change, another component of MU’s total return these past 20 years has been the payment by Micron Technology Inc. of $0.10/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of .4/share, we calculate that MU has a current yield of approximately 0.59%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .4 against the original $20.80/share purchase price. This works out to a yield on cost of 2.84%.
