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

— 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 twenty year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Gartner Inc (NYSE: IT) back in 1999: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 10/25/1999
$10,000

10/25/1999
$109,530

10/22/2019
End date: 10/22/2019
Start price/share: $13.06
End price/share: $142.98
Starting shares: 765.55
Ending shares: 765.55
Dividends reinvested/share: $0.00
Total return: 994.58%
Average annual return: 12.71%
Starting investment: $10,000.00
Ending investment: $109,530.16

As we can see, the twenty year investment result worked out quite well, with an annualized rate of return of 12.71%. This would have turned a $10K investment made 20 years ago into $109,530.16 today (as of 10/22/2019). On a total return basis, that’s a result of 994.58% (something to think about: how might IT 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:
