A trader with experience, working in a firm with deep pockets and terabytes of historical data and FPGAs that can execute his/her strategy and a legal team and an engineering team... can outperform you yes x)
But I should say that any engineer familiar with the AI tech stack could have bought NVDA at any point in the last five years knowing how big their moat is. That same engineer could have sold monthly covered calls, taking 5 minutes out of every month to do so.
And before you say it, no, they wouldn't be full port NVDA.
Extrapolating from past data with N=1 to demonstrate that "any tech person can outperform the index" shows a crass lack of mathematical reasoning, which in my opinion demonstrates why you're unsuited to professional trading.
