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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a twenty year holding period for an investor who was considering ABIOMED, Inc. (NASD: ABMD) back in 2000, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 08/14/2000


End date: 08/13/2020
Start price/share: $21.19
End price/share: $308.37
Starting shares: 471.92
Ending shares: 471.92
Dividends reinvested/share: $0.00
Total return: 1,355.26%
Average annual return: 14.32%
Starting investment: $10,000.00
Ending investment: $145,573.15

As shown above, the twenty year investment result worked out quite well, with an annualized rate of return of 14.32%. This would have turned a $10K investment made 20 years ago into $145,573.15 today (as of 08/13/2020). On a total return basis, that’s a result of 1,355.26% (something to think about: how might ABMD shares perform over the next 20 years?).
