Support. Damn near close to stopping me out. The structure remains constructive though it’s testing our mettle.
Fractional (Fed managed) banking will do that. Read a book or two on the subject.
The Fed doesn't dare pull QE/ZIRP because it will cause the collapse of the bubble economy they've created. All they can do is to continue to prop it up, which will only put things off and increase the magnitude of the eventual crash.
