3x leverage on VTI/VOO yields 20% annual return over the past 30 years.

Even you, a passive index fund investor, can do this in your Schwab/Fidelity account.

Now consider algorithmic prop trading firms with 10x, 20x leverage. You do the math.

For reference, most people take 5x leverage on their house (20% down payment).

You think Citadel and Jane Street are fairy tales? The comment you replied to gave plenty of very pointed evidence. Even "bad" trading firms are disappointed to make 20% returns year over year...
