“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 twenty year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Hologic Inc (NASD: HOLX) back in 1999. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 11/22/1999
$10,000

11/22/1999
$396,099

11/19/2019
End date: 11/19/2019
Start price/share: $1.19
End price/share: $47.15
Starting shares: 8,403.36
Ending shares: 8,403.36
Dividends reinvested/share: $0.00
Total return: 3,862.18%
Average annual return: 20.19%
Starting investment: $10,000.00
Ending investment: $396,099.54

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 20.19%. This would have turned a $10K investment made 20 years ago into $396,099.54 today (as of 11/19/2019). On a total return basis, that’s a result of 3,862.18% (something to think about: how might HOLX shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
