“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 ABIOMED, Inc. (NASD: ABMD) back in 2016: 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: 07/27/2016


End date: 07/26/2021
Start price/share: $115.97
End price/share: $325.00
Starting shares: 86.23
Ending shares: 86.23
Dividends reinvested/share: $0.00
Total return: 180.24%
Average annual return: 22.89%
Starting investment: $10,000.00
Ending investment: $28,027.39

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 22.89%. This would have turned a $10K investment made 5 years ago into $28,027.39 today (as of 07/26/2021). On a total return basis, that’s a result of 180.24% (something to think about: how might ABMD shares perform over the next 5 years?).
