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

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a five year holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 5 years to 2016, investors considering an investment into shares of Intuitive Surgical Inc (NASD: ISRG) may have been pondering this very question and thinking about their potential investment result over a full five year time horizon. Here’s how that would have worked out.

Start date: 01/22/2016


End date: 01/21/2021
Start price/share: $188.70
End price/share: $798.67
Starting shares: 52.99
Ending shares: 52.99
Dividends reinvested/share: $0.00
Total return: 323.25%
Average annual return: 33.43%
Starting investment: $10,000.00
Ending investment: $42,326.33

The above analysis shows the five year investment result worked out exceptionally well, with an annualized rate of return of 33.43%. This would have turned a $10K investment made 5 years ago into $42,326.33 today (as of 01/21/2021). On a total return basis, that’s a result of 323.25% (something to think about: how might ISRG shares perform over the next 5 years?).
