“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Advanced Micro Devices Inc (NASD: AMD) back in 2015: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 11/02/2015
$10,000

11/02/2015
$343,818

10/30/2020
End date: 10/30/2020
Start price/share: $2.19
End price/share: $75.29
Starting shares: 4,566.21
Ending shares: 4,566.21
Dividends reinvested/share: $0.00
Total return: 3,337.90%
Average annual return: 103.05%
Starting investment: $10,000.00
Ending investment: $343,818.68

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 103.05%. This would have turned a $10K investment made 5 years ago into $343,818.68 today (as of 10/30/2020). On a total return basis, that’s a result of 3,337.90% (something to think about: how might AMD shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more investment quote to leave you with:
“October is one of the peculiarly dangerous months to speculate in stocks. The others are July, January, September, April, November, May, March, June, December, August and February.” — Mark Twain
