On some occasions you see equities in a slow death spiral supported invariably by ZIRP and QE. It's not a new experience for markets since we've had both factors dominating markets over the past three years. When the punchbowl is removed we move sharply lower as this seems to be the only support available. Stocks sell-off on sharply higher volume from both the public and insiders. Poor economic data (Jobless Claims) then drives Fed governors to the speaking circuit with hints of QE and further stimulus as Dudley and Yellen did Thursday, and markets rally. Wash, rinse and repeat.
