“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 Boston Scientific Corp. (NYSE: BSX)? Today, we examine the outcome of a twenty year investment into the stock back in 1999.

Start date: 05/06/1999


End date: 05/03/2019
Start price/share: $20.38
End price/share: $37.20
Starting shares: 490.68
Ending shares: 490.68
Dividends reinvested/share: $0.00
Total return: 82.53%
Average annual return: 3.05%
Starting investment: $10,000.00
Ending investment: $18,240.28

As shown above, the twenty year investment result worked out as follows, with an annualized rate of return of 3.05%. This would have turned a $10K investment made 20 years ago into $18,240.28 today (as of 05/03/2019). On a total return basis, that’s a result of 82.53% (something to think about: how might BSX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
“The most important quality for an investor is temperament, not intellect. You need a temperament that neither derives great pleasure from being with the crowd or against the crowd.” — Warren Buffett
