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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a decade-long holding period for an investor who was considering Micron Technology Inc. (NASD: MU) back in 2010, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 12/17/2010


End date: 12/16/2020
Start price/share: $8.21
End price/share: $72.99
Starting shares: 1,218.03
Ending shares: 1,218.03
Dividends reinvested/share: $0.00
Total return: 789.04%
Average annual return: 24.41%
Starting investment: $10,000.00
Ending investment: $88,934.99

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 24.41%. This would have turned a $10K investment made 10 years ago into $88,934.99 today (as of 12/16/2020). On a total return basis, that’s a result of 789.04% (something to think about: how might MU shares perform over the next 10 years?).
