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

— 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 twenty year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Synopsys Inc (NASD: SNPS) back in 2003: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full twenty year investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 10/13/2003
$10,000

10/13/2003
  $175,641

10/11/2023
End date: 10/11/2023
Start price/share: $28.19
End price/share: $494.95
Starting shares: 354.74
Ending shares: 354.74
Dividends reinvested/share: $0.00
Total return: 1,655.76%
Average annual return: 15.40%
Starting investment: $10,000.00
Ending investment: $175,641.63

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 15.40%. This would have turned a $10K investment made 20 years ago into $175,641.63 today (as of 10/11/2023). On a total return basis, that’s a result of 1,655.76% (something to think about: how might SNPS shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Another great investment quote to think about:
“Unless you can watch your stock holding decline by 50% without becoming panic-stricken, you should not be in the stock market.” — Warren Buffett
