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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a twenty year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Micron Technology Inc. (NASD: MU) back in 2001, holding through to today.

Start date: 02/02/2001


End date: 02/01/2021
Start price/share: $41.20
End price/share: $80.43
Starting shares: 242.72
Ending shares: 242.72
Dividends reinvested/share: $0.00
Total return: 95.22%
Average annual return: 3.40%
Starting investment: $10,000.00
Ending investment: $19,524.05

The above analysis shows the twenty year investment result worked out as follows, with an annualized rate of return of 3.40%. This would have turned a $10K investment made 20 years ago into $19,524.05 today (as of 02/01/2021). On a total return basis, that’s a result of 95.22% (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.]

Another great investment quote to think about:
“Investors should always keep in mind that the most important metric is not the returns achieved but the returns weighed against the risks incurred. Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.” — Seth Klarman
