“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 2005, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 08/15/2005
$10,000

08/15/2005
  $1,026,288

08/14/2025
End date: 08/14/2025
Start price/share: $2.25
End price/share: $230.98
Starting shares: 4,444.44
Ending shares: 4,444.44
Dividends reinvested/share: $0.00
Total return: 10,165.78%
Average annual return: 26.04%
Starting investment: $10,000.00
Ending investment: $1,026,288.24

The above analysis shows the two-decade investment result worked out exceptionally well, with an annualized rate of return of 26.04%. This would have turned a $10K investment made 20 years ago into $1,026,288.24 today (as of 08/14/2025). On a total return basis, that’s a result of 10,165.78% (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.]
