This graph shows 3-month options volatility skew for GLD (gold ETF).
The blue line (right axis) = put skew: how much pricier OTM puts are vs at-the-money options. It just spiked sharply higher.
Darker line (left axis) = call skew, recently lower.
High put skew = traders aggressively buying downside protection/insurance. Even after gold’s big rally, the options market is pricing in more fear of a drop than upside momentum.
