And are there any quant funds that consistently make money? No. It's like professional gambling. Susquehanna actually bets on sports too. Constant losses (hopefully slightly) offset by gains. There's no such as a trader with high accuracy/precision. If you can even edge out 1% (gain-loss) you'll be a billionaire from $0 very quickly. A positive edge is so exceptionally rare, it's like a startup -> unicorn. It would be the equivalent of owning a casino with trillions of dollars being played nonstop. It almost never happens.

If there was any fixed analytic solution to behavior then a simple neural network would approximate it quite easily. It's almost all noise with only spurious correlations and misleading patterns that don't repeat.
