I did look up numbers before I made that claim:
From Yahoo Finance
GME Jan 1, 2016: $7.09, $5.49 adjusted (accounting for dividend disbursements)
GME Jan 1, 2026: $20.09
266% or 365% return depending on how you count dividends. 365% for GME vs. 306% for S&P 500 over the same period (also using adjusted for dividend numbers).
For the previous 10 years, dividends reinvested, GME returned 14.59% per year, SP500 did 15.376% per year. Considering the much, much higher risk of owning a single stock, the risk adjusted return of SP500 is much higher than GME.
