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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into F5 Inc (NASD: FFIV) back in 2019: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 12/23/2019
$10,000

12/23/2019
  $18,142

12/20/2024
End date: 12/20/2024
Start price/share: $139.04
End price/share: $252.25
Starting shares: 71.92
Ending shares: 71.92
Dividends reinvested/share: $0.00
Total return: 81.42%
Average annual return: 12.66%
Starting investment: $10,000.00
Ending investment: $18,142.91

As we can see, the five year investment result worked out quite well, with an annualized rate of return of 12.66%. This would have turned a $10K investment made 5 years ago into $18,142.91 today (as of 12/20/2024). On a total return basis, that’s a result of 81.42% (something to think about: how might FFIV shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
