“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty 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 twenty year investment into the stock back in 1999.

Start date: 09/27/1999
$10,000

09/27/1999
$238,684

09/26/2019
End date: 09/26/2019
Start price/share: $7.44
End price/share: $177.65
Starting shares: 1,344.09
Ending shares: 1,344.09
Dividends reinvested/share: $0.00
Total return: 2,287.77%
Average annual return: 17.18%
Starting investment: $10,000.00
Ending investment: $238,684.62

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 17.18%. This would have turned a $10K investment made 20 years ago into $238,684.62 today (as of 09/26/2019). On a total return basis, that’s a result of 2,287.77% (something to think about: how might ABMD shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
