1. This is actually currently being debated within the Fed. 2. I didn't say the Fed is buying stocks. They are buying the stable assets that the mega-wealthy have in their portfolio. Mega-wealthy don't have all their eggs in one basket. The Fed in solidifying a portion of their basket which allows mega-wealthy to retain the added risk in the markets.
This is not aging well.

As for this particular situation, Fed buys corporate bonds, making companies less risky for stockowners. They also push those yields down, so capital goes to stocks to seek better returns.
Tell me how Federal reserve's actions don't prop up the stock market?
The Fed's "Rube Goldberg activity" holds up the stock market...uuuuntil it doesn't.
