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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a ten year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Amazon.com Inc (NASD: AMZN) back in 2011: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full ten year investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 05/25/2011
$10,000

05/25/2011
$168,817

05/24/2021
End date: 05/24/2021
Start price/share: $192.26
End price/share: $3,244.99
Starting shares: 52.01
Ending shares: 52.01
Dividends reinvested/share: $0.00
Total return: 1,587.81%
Average annual return: 32.64%
Starting investment: $10,000.00
Ending investment: $168,817.44

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 32.64%. This would have turned a $10K investment made 10 years ago into $168,817.44 today (as of 05/24/2021). On a total return basis, that’s a result of 1,587.81% (something to think about: how might AMZN shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
