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

— Warren Buffett

A critical pearl of wisdom from Warren Buffett teaches us that with any potential stock investment we may make, as soon as our buy order is filled we will have a choice: to remain a co-owner of that company for the long haul, or to react to the inevitable short-term ups and downs that the stock market is famous for (sometimes sharp ups and downs).

The reality of this choice forces us to challenge our confidence in any given company we might invest into, and keep our eyes on the long-term time horizon. The market may go up and down the interim, but over a twenty year holding period, will the investment succeed?

Back in 2000, investors may have been asking themselves that very question about Mettler-Toledo International, Inc. (NYSE: MTD). Let’s examine what would have happened over a twenty year holding period, had you invested in MTD shares back in 2000 and held on.

Start date: 01/24/2000
$10,000

01/24/2000
$241,037

01/22/2020
End date: 01/22/2020
Start price/share: $34.62
End price/share: $834.92
Starting shares: 288.81
Ending shares: 288.81
Dividends reinvested/share: $0.00
Total return: 2,311.32%
Average annual return: 17.24%
Starting investment: $10,000.00
Ending investment: $241,037.13

As we can see, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 17.24%. This would have turned a $10K investment made 20 years ago into $241,037.13 today (as of 01/22/2020). On a total return basis, that’s a result of 2,311.32% (something to think about: how might MTD shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

One more piece of investment wisdom to leave you with:
“While some might mistakenly consider value investing a mechanical tool for identifying bargains, it is actually a comprehensive investment philosophy that emphasizes the need to perform in-depth fundamental analysis, pursue long-term investment results, limit risk, and resist crowd psychology.” — Seth Klarman
