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

— 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 two-decade holding period for an investor who was considering Amazon.com Inc (NASD: AMZN) back in 1999, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 12/13/1999
$10,000

12/13/1999
$170,536

12/11/2019
End date: 12/11/2019
Start price/share: $102.50
End price/share: $1,748.72
Starting shares: 97.56
Ending shares: 97.56
Dividends reinvested/share: $0.00
Total return: 1,606.07%
Average annual return: 15.23%
Starting investment: $10,000.00
Ending investment: $170,536.46

As shown above, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 15.23%. This would have turned a $10K investment made 20 years ago into $170,536.46 today (as of 12/11/2019). On a total return basis, that’s a result of 1,606.07% (something to think about: how might AMZN shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more investment quote to leave you with:
“As time goes on, I get more and more convinced that the right method of investment is to put fairly large sums into enterprises which one thinks one knows something about and in the management of which one thoroughly believes.” — John Maynard Keynes
