“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 Warner Bros Discovery Inc (NASD: WBD)? Today, we examine the outcome of a two-decade investment into the stock back in 2005.

Start date: 10/28/2005
$10,000

10/28/2005
  $65,292

10/27/2025
End date: 10/27/2025
Start price/share: $3.22
End price/share: $21.04
Starting shares: 3,105.59
Ending shares: 3,105.59
Dividends reinvested/share: $0.00
Total return: 553.42%
Average annual return: 9.83%
Starting investment: $10,000.00
Ending investment: $65,292.90

As we can see, the two-decade investment result worked out well, with an annualized rate of return of 9.83%. This would have turned a $10K investment made 20 years ago into $65,292.90 today (as of 10/27/2025). On a total return basis, that’s a result of 553.42% (something to think about: how might WBD shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
