Many quant trading firms make 50%-100% annual returns, each year, over the past 15-20 years. The secret is leverage. And they do not accept outside investor money.
Many hedge funds outperform the market. However, the returns after fees, to the passive outside investor underperform S&P500.
But yes, publicly traded active ETFs generally underperform. But counter example is VGT or QQQ, both historically outperformed S&P500.
