“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 Incyte Corporation (NASD: INCY) 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: 03/15/1999
$10,000

03/15/1999
$70,693

03/13/2019
End date: 03/13/2019
Start price/share: $12.03
End price/share: $85.06
Starting shares: 831.26
Ending shares: 831.26
Dividends reinvested/share: $0.00
Total return: 607.07%
Average annual return: 10.27%
Starting investment: $10,000.00
Ending investment: $70,693.61

As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 10.27%. This would have turned a $10K investment made 20 years ago into $70,693.61 today (as of 03/13/2019). On a total return basis, that’s a result of 607.07% (something to think about: how might INCY shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
