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

— 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 decade-long period?

Today, let’s look backwards in time to 2009, 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 decade-long holding period.

Start date: 11/20/2009
$10,000

11/20/2009
$226,400

11/19/2019
End date: 11/19/2019
Start price/share: $8.14
End price/share: $184.34
Starting shares: 1,228.50
Ending shares: 1,228.50
Dividends reinvested/share: $0.00
Total return: 2,164.62%
Average annual return: 36.60%
Starting investment: $10,000.00
Ending investment: $226,400.87

As shown above, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 36.60%. This would have turned a $10K investment made 10 years ago into $226,400.87 today (as of 11/19/2019). On a total return basis, that’s a result of 2,164.62% (something to think about: how might ABMD shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
