The ETF era permits risk shifting techniques like the portfolio Insurance technique that led to the 87 crash. Such activity is hard to track or diagnose until a post-mortem becomes possible after the crash. Several bad theories of what happened in 87 were still being touted after the market began to recover but before all the data was analyzed. So revisitation or just part of the wall of worry?
