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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Berkshire Hathaway Inc New (NYSE: BRK.B)? Today, we examine the outcome of a twenty year investment into the stock back in 1999.

Start date: 08/23/1999
$10,000

08/23/1999
$48,857

08/22/2019
End date: 08/22/2019
Start price/share: $41.14
End price/share: $201.01
Starting shares: 243.07
Ending shares: 243.07
Dividends reinvested/share: $0.00
Total return: 388.60%
Average annual return: 8.25%
Starting investment: $10,000.00
Ending investment: $48,857.97

As we can see, the twenty year investment result worked out well, with an annualized rate of return of 8.25%. This would have turned a $10K investment made 20 years ago into $48,857.97 today (as of 08/22/2019). On a total return basis, that’s a result of 388.60% (something to think about: how might BRK.B shares perform over the next 20 years?).
