“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten 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 ten year investment into the stock back in 2012.

Start date: 03/26/2012


End date: 03/23/2022
Start price/share: $8.25
End price/share: $75.65
Starting shares: 1,212.12
Ending shares: 1,215.13
Dividends reinvested/share: $0.20
Total return: 819.25%
Average annual return: 24.84%
Starting investment: $10,000.00
Ending investment: $91,891.14

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 24.84%. This would have turned a $10K investment made 10 years ago into $91,891.14 today (as of 03/23/2022). On a total return basis, that’s a result of 819.25% (something to think about: how might MU shares perform over the next 10 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 10 years has been the payment by Micron Technology Inc. of $0.20/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 0.53%. 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 $8.25/share purchase price. This works out to a yield on cost of 6.42%.

One more piece of investment wisdom to leave you with:
“The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.” — Warren Buffett
