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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long 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 decade-long investment into the stock back in 2015.

Start date: 01/07/2015
$10,000

01/07/2015
  $3,362

01/06/2025
End date: 01/06/2025
Start price/share: $32.21
End price/share: $10.83
Starting shares: 310.46
Ending shares: 310.46
Dividends reinvested/share: $0.00
Total return: -66.38%
Average annual return: -10.32%
Starting investment: $10,000.00
Ending investment: $3,362.77

The above analysis shows the decade-long investment result worked out poorly, with an annualized rate of return of -10.32%. This would have turned a $10K investment made 10 years ago into $3,362.77 today (as of 01/06/2025). On a total return basis, that’s a result of -66.38% (something to think about: how might WBD shares perform over the next 10 years?).
