“With growth momentum nearing its peak and rates increasing further with a hawkish Fed, the asymmetry for equities is turning increasingly negative. This also means more vulnerability to potential shocks, e.g., from European politics, US policy, commodities and China. The increase in risk appetite in recent months and strong positioning by systematic investors such as CTAs and risk parity funds increases ‘vol of vol’ risk, i.e., the potential for a sharp correction.”
