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

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a ten year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into United Airlines Holdings Inc (NASD: UAL) back in 2009: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full ten year investment time horizon and then actually held for these past 10 years, here’s how that investment would have turned out.

Start date: 12/10/2009
$10,000

12/10/2009
$86,133

12/09/2019
End date: 12/09/2019
Start price/share: $10.17
End price/share: $87.61
Starting shares: 983.28
Ending shares: 983.28
Dividends reinvested/share: $0.00
Total return: 761.46%
Average annual return: 24.02%
Starting investment: $10,000.00
Ending investment: $86,133.76

As we can see, the ten year investment result worked out exceptionally well, with an annualized rate of return of 24.02%. This would have turned a $10K investment made 10 years ago into $86,133.76 today (as of 12/09/2019). On a total return basis, that’s a result of 761.46% (something to think about: how might UAL shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Here’s one more great investment quote before you go:
“You can’t be a good value investor without being an independent thinker; you’re seeing valuations that the market is not appreciating. But it’s critical that you understand why the market isn’t seeing the value you do.” — Joel Greenblatt
