Hari Krishnan, head of volatility strategies at SCT Capital, sits down with Ash Bennington to discuss how the "dominant agents" (namely market makers, high frequency traders, passive products, and central banks) have created a feedback loop that is distorting the distribution of returns, causing median returns to be higher but downside skew to be more negative than ever. Hari and Ash will also discuss the precarious positioning of levered and inverse ETFs and why S&P 500 E-Mini Futures are the ultimate barometer of sentiment.
