“I buy on the assumption that they could close the market the next day and not reopen it for five years.”
— Warren Buffett
The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Biogen Inc (NASD: BIIB)? Today, we examine the outcome of a five year investment into the stock back in 2020.
| Start date: | 04/24/2020 |

| End date: | 04/23/2025 | ||||
| Start price/share: | $297.80 | ||||
| End price/share: | $118.17 | ||||
| Starting shares: | 33.58 | ||||
| Ending shares: | 33.58 | ||||
| Dividends reinvested/share: | $0.00 | ||||
| Total return: | -60.32% | ||||
| Average annual return: | -16.88% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $3,967.60 | ||||
The above analysis shows the five year investment result worked out poorly, with an annualized rate of return of -16.88%. This would have turned a $10K investment made 5 years ago into $3,967.60 today (as of 04/23/2025). On a total return basis, that’s a result of -60.32% (something to think about: how might BIIB shares perform over the next 5 years?).
