In studying skew I've been advised to focus on understanding on components that affect it. One such component that's been recommended to me is the relationship btwn RV-IV and realized skew. Allegedly, there should be a strong correlation btwn the 2 (skew steepens when RV exceeds implied), but when I regress one on the other, I find no such relationship. Am I wasting my time?

I also cannot think of some fundamental theory that might explain the relationship. What would be the theoretical underpinning for why this happens? Hedgers buying tails?
