First let’s explain exactly what a “Fed Put” is. A Fed put is defined as: The confidence of Wall Street that the Fed will lower interest rates and print money to support the market until economic strength will be strong enough to carry stocks higher. The term “Put” is ascribed to this because a put option is basically a contract that offers a buyer protection from falling asset prices. It was first coined under the Chairmanship of Alan Greenspan when he lowered interest rates and printed money to rescue Wall Street from its 22% Black Monday crash back in 1987. The practice of bailing out stocks was institutionalized by Ben Bernanke; and then became a bonafide tradition perpetuated by Janet Yellen.
