“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— Warren Buffett
The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a twenty year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in Biogen Inc (NASD: BIIB) back in 2003, holding through to today.

As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 11.02%. This would have turned a $10K investment made 20 years ago into $80,937.33 today (as of 03/21/2023). On a total return basis, that’s a result of 709.46% (something to think about: how might BIIB shares perform over the next 20 years?).
