“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— 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 five 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 F5 Inc (NASD: FFIV) back in 2020, holding through to today.

Start date: 10/08/2020
$10,000

10/08/2020
  $25,830

10/07/2025
End date: 10/07/2025
Start price/share: $128.06
End price/share: $330.76
Starting shares: 78.09
Ending shares: 78.09
Dividends reinvested/share: $0.00
Total return: 158.29%
Average annual return: 20.90%
Starting investment: $10,000.00
Ending investment: $25,830.42

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 20.90%. This would have turned a $10K investment made 5 years ago into $25,830.42 today (as of 10/07/2025). On a total return basis, that’s a result of 158.29% (something to think about: how might FFIV shares perform over the next 5 years?).
