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

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Biogen Inc (NASD: BIIB) back in 2004. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 05/17/2004
$10,000

05/17/2004
  $39,530

05/16/2024
End date: 05/16/2024
Start price/share: $58.15
End price/share: $230.04
Starting shares: 171.97
Ending shares: 171.97
Dividends reinvested/share: $0.00
Total return: 295.60%
Average annual return: 7.11%
Starting investment: $10,000.00
Ending investment: $39,530.04

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 7.11%. This would have turned a $10K investment made 20 years ago into $39,530.04 today (as of 05/16/2024). On a total return basis, that’s a result of 295.60% (something to think about: how might BIIB shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Here’s one more great investment quote before you go:
“The best way to measure your investing success is not by whether you’re beating the market but by whether you’ve put in place a financial plan and a behavioral discipline that are likely to get you where you want to go.” — Benjamin Graham
