Any book recommendation? I come from a "boglehead"-centric approach [1], stating that the market is so efficient that it's virtually impossible to beat it in the long term as a mere mortal, so one might as well just buy indexes and get the market return, hoping that in the long term capitalism will continue thriving. And that's what I've done, fully investing my high 6 figure (soon to be 7) liquid net worth into index funds.

The only exception to the rule would be if one has some sort of technical advantage (e.g. HFT infrastructures) or "insider" information.

Was curious to hear if you have any resources that in your opinion could make me change my stance? Thanks
