While equities sold off last week on disappointing Tech earnings, implied vols were fairly muted across asset classes. Equity vol ended the week unchanged, with the VIX® Index hovering around 19.5%. Even on Friday’s large sell-off, SPX® 1M fixed strike vols increased by just 0.6pt, while both put skew and put convexity fell as investors monetized existing hedges. The equity sell-off was almost entirely driven by Tech, with 9 of the 11 S&P sectors ending up on the week (led by Healthcare +3% vs. Comm Services -8.5%). The extreme sector rotation is another reason why index volatility has been so muted.
Positioning in TLT options has flipped notably in recent weeks, with skew falling from near a 1-year high to near a 1-year low on stronger demand for upside calls. The fear of higher rates has dissipated, with more investors now positioning for long-end yields to fall on the back of a more uncertain macro outlook. The correlation between stocks and bonds has also flipped. The 1M rolling correlation between the SPX Index and the 10Y Treasury yield has jumped from -70% to +40% over the past month as investor focus shifts from inflation to growth risk.
Positioning in single stock options has also shifted notably, with call demand dropping sharply and hedging demand increasing. The percent of stocks in the S&P top 100 trading with inverted call skew (a sign of extreme bullish sentiment) has fallen from a high of 44% in early October to just 10% now. Looking at retail flow on Cboe’s exchanges, retail put buying in the mega-cap Tech stocks hit a YTD high last week, accounting for 34% of all opening trades (vs. average of 24%).
