“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into ABIOMED, Inc. (NASD: ABMD)? Today, we examine the outcome of a ten year investment into the stock back in 2009.

Start date: 06/05/2009
$10,000

06/05/2009
$365,757

06/04/2019
End date: 06/04/2019
Start price/share: $7.30
End price/share: $267.06
Starting shares: 1,369.86
Ending shares: 1,369.86
Dividends reinvested/share: $0.00
Total return: 3,558.36%
Average annual return: 43.31%
Starting investment: $10,000.00
Ending investment: $365,757.39

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 43.31%. This would have turned a $10K investment made 10 years ago into $365,757.39 today (as of 06/04/2019). On a total return basis, that’s a result of 3,558.36% (something to think about: how might ABMD shares perform over the next 10 years?).
