“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 decade-long holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Inc (NASD: AMZN) back in 2010: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full decade-long investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 09/17/2010


End date: 09/16/2020
Start price/share: $148.32
End price/share: $3,078.10
Starting shares: 67.42
Ending shares: 67.42
Dividends reinvested/share: $0.00
Total return: 1,975.31%
Average annual return: 35.41%
Starting investment: $10,000.00
Ending investment: $207,600.67

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 35.41%. This would have turned a $10K investment made 10 years ago into $207,600.67 today (as of 09/16/2020). On a total return basis, that’s a result of 1,975.31% (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.]
