“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a twenty year period?

Today, let’s look backwards in time to 1999, and take a look at what happened to investors who asked that very question about ABIOMED, Inc. (NASD: ABMD), by taking a look at the investment outcome over a twenty year holding period.

Start date: 05/10/1999
$10,000

05/10/1999
$330,262

05/08/2019
End date: 05/08/2019
Start price/share: $7.88
End price/share: $260.27
Starting shares: 1,269.04
Ending shares: 1,269.04
Dividends reinvested/share: $0.00
Total return: 3,202.92%
Average annual return: 19.10%
Starting investment: $10,000.00
Ending investment: $330,262.42

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 19.10%. This would have turned a $10K investment made 20 years ago into $330,262.42 today (as of 05/08/2019). On a total return basis, that’s a result of 3,202.92% (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.]
