Debt is definitely increasing, but what I have read mostly says stock buybacks are going down not up and the debt is not earmarked to stock buybacks.
US stocks are trading at 143% market cap to GDP with a forward P/E north of 24....and increasing. I guess 4+ Trillion in 8 weeks from the fed made everything great again.
Corporate debt keep setting almost daily new records as more companies are borrowing as both a buffer and to do stock buybacks.
This madness will end badly.
