And no, foreign demand will not come in and save the day and Fed YCC hopes is just pure delusion, Fed isn't going to risk losing US dollar reserve status just to save a bunch of zombie corporations and over levered people. I'm pretty sure they're just going to let this one burn. Equities will snap back to reality in a harsh way very shortly.
And no, the argument that higher rates are bullish for stocks is bunk. That may have been correct in a different market environment, but not one in which everyone and everything is levered. Also, people who say that are discounting the knock on effects it has on other countries, say like Brazil which was just forced to hike rates just now to stay competitive.
