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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a two-decade holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Charles River Laboratories International Inc. (NYSE: CRL)? Today, we examine the outcome of a two-decade investment into the stock back in 2004.

Start date: 08/23/2004
$10,000

08/23/2004
  $47,160

08/21/2024
End date: 08/21/2024
Start price/share: $43.31
End price/share: $204.38
Starting shares: 230.89
Ending shares: 230.89
Dividends reinvested/share: $0.00
Total return: 371.90%
Average annual return: 8.06%
Starting investment: $10,000.00
Ending investment: $47,160.24

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 8.06%. This would have turned a $10K investment made 20 years ago into $47,160.24 today (as of 08/21/2024). On a total return basis, that’s a result of 371.90% (something to think about: how might CRL shares perform over the next 20 years?).
