Testing The Bubble Index

In the next couple of days, The Bubble Index will have calculated a 153, 256, and 512 day window for almost 600 stocks and around 30 indices, currencies, and commodities. With all this data I will be testing the relationship between the index and price movements. My hypothesis: The Bubble Index predicts monthly price movements (up or down) of 20% or higher more than 21 days in advance of the movement.
