“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period for an investor who was considering Micron Technology Inc. (NASD: MU) back in 2015, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 11/24/2015
$10,000

11/24/2015
$41,056

11/23/2020
End date: 11/23/2020
Start price/share: $15.63
End price/share: $64.18
Starting shares: 639.80
Ending shares: 639.80
Dividends reinvested/share: $0.00
Total return: 310.62%
Average annual return: 32.62%
Starting investment: $10,000.00
Ending investment: $41,056.42

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 32.62%. This would have turned a $10K investment made 5 years ago into $41,056.42 today (as of 11/23/2020). On a total return basis, that’s a result of 310.62% (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.]
