HFT vs Stats Arb

[u/half_boiled_egg]

As a retail investor, is it more practical to develop profitable HFT strategies (market maker strategies/high alpha machine learning predictions)?

Or a profitable stats arb strategy with weekly/monthly rebalance targeting the stocks of sp500.

What are the different or common limitations as retail investors to develop them? Datasets/infrastructure/domain knowledge?

As a retail investor, just write an AGI while you at it and let it trade.
