“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 Align Technology Inc (NASD: ALGN)? Today, we examine the outcome of a ten year investment into the stock back in 2011.

Start date: 06/28/2011
$10,000

06/28/2011
$273,930

06/25/2021
End date: 06/25/2021
Start price/share: $22.45
End price/share: $614.98
Starting shares: 445.43
Ending shares: 445.43
Dividends reinvested/share: $0.00
Total return: 2,639.33%
Average annual return: 39.24%
Starting investment: $10,000.00
Ending investment: $273,930.35

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 39.24%. This would have turned a $10K investment made 10 years ago into $273,930.35 today (as of 06/25/2021). On a total return basis, that’s a result of 2,639.33% (something to think about: how might ALGN shares perform over the next 10 years?).

One more piece of investment wisdom to leave you with:
“Thousands of experts study overbought indicators, head-and-shoulder patterns, put-call ratios, the Fed’s policy on money supply…and they can’t predict markets with any useful consistency, any more than the gizzard squeezers could tell the Roman emperors when the Huns would attack.” — Peter Lynch
