Correct me if I'm wrong, but I remember reading that during the AMC or maybe GME craze, it was the option buying that was causing the squeeze. Its much cheaper to just buy an option, and then let the MM have to hedge with buying the stock, correct? So it perhaps doesn't take a lot of cash to force the market higher. Can this be accounted for by digging into the Call/Put volumes?
AMC, GME was because there were 10,000s of investors buying calls (essentially cornering the market of delta and gamma).
The idea in this thread is different. It's that there are investors looking have capital to buy assets if they selloff. These same investors didn't put all that capital to work 10% ago and at the same time those same investors are putting capital to work now causing the market to rally that those investors are waiting to end so they put this extra capital to work. It's circular logic.
