“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 Keysight Technologies Inc (NYSE: KEYS) back in 2021: 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: 02/24/2021
$10,000

02/24/2021
  $17,056

02/23/2026
End date: 02/23/2026
Start price/share: $143.64
End price/share: $245.00
Starting shares: 69.62
Ending shares: 69.62
Dividends reinvested/share: $0.00
Total return: 70.57%
Average annual return: 11.27%
Starting investment: $10,000.00
Ending investment: $17,056.52

The above analysis shows the five year investment result worked out quite well, with an annualized rate of return of 11.27%. This would have turned a $10K investment made 5 years ago into $17,056.52 today (as of 02/23/2026). On a total return basis, that’s a result of 70.57% (something to think about: how might KEYS shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
