When the ratio is extremely high, VIX tends to spike anywhere from one week, to 1 month afterwards. See August 2015, Dec 2016. When the ratio is extremely low, VIX tends to fall, see January 2019, or October 2015.

Are there cases where the divergence occurred and returned back to normal with no unusual VIX activity during that time?
