“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 2020: 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: | 12/10/2020 |
|
|||
| End date: | 12/09/2025 | ||||
| Start price/share: | $171.41 | ||||
| End price/share: | $257.98 | ||||
| Starting shares: | 58.34 | ||||
| Ending shares: | 58.34 | ||||
| Dividends reinvested/share: | $0.00 | ||||
| Total return: | 50.50% | ||||
| Average annual return: | 8.52% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $15,050.43 | ||||
As shown above, the five year investment result worked out well, with an annualized rate of return of 8.52%. This would have turned a $10K investment made 5 years ago into $15,050.43 today (as of 12/09/2025). On a total return basis, that’s a result of 50.50% (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.]
