Trust, but hedge: Quietly violent summer lingers as bulls buy crash protection

• S&P call-to-put ratios are at their most bullish levels in at least a year across all expiration timeframes, with the ratio of 25-delta puts to calls at the lowest since mid-2024 following a post-earnings rally squeeze
• Demand for deep out-of-the-money crash protection (10-delta puts) remains unusually high at the 66th percentile of the past five years, indicating investors are hedging against sharp downside moves despite bullish positioning
• Russell 2000 small-cap volatility dropped to a 2nd percentile low over five years despite a 20% year-to-date rally, with traders viewing small-caps as a relative 'volatility safe-haven' compared to large-cap indexes

Market Summary: Options Activity Reveals Mixed Sentiment Despite Market Highs

Key Market Developments

Despite the S&P 500 reaching all-time highs and the VIX near year-to-date lows, the summer has featured significant underlying volatility. The semiconductor sector experienced a 25% pullback, triggering record put-buying activity in the sector. However, broader market selling remained contained to brief episodes.

Options Positioning Data

Bullish Indicators:

• S&P 500 call-to-put ratios at the most bullish levels in at least a year across multiple expiration periods
• Cboe set a record for call-option trading volume
• Nasdaq options logged one of the most bullish days in a decade
• The ratio of 25-delta puts to calls hit the lowest level since mid-2024

Hedging Activity:

• Despite bullish positioning, traders are maintaining elevated levels of deep out-of-the-money puts
• The ratio of 10-delta puts to 25-delta puts sits in the 66th percentile high over five years
• "Crash protection" hedges remain unusually popular, suggesting underlying caution

Sector Performance

The Russell 2000 small-cap index has rallied 20% year-to-date, outperforming both the S&P 500 and Nasdaq 100. Small-cap volatility dropped below 17 last week, reaching a 2nd percentile low over the past five years, making small-caps a potential "volatility safe-haven."

Market Implications

According to Mandy Xu, Cboe's head of derivatives market intelligence, the positioning reflects a "trust but hedge" strategy. While traders weren't prepared for the recent sharp post-earnings rally, they're simultaneously maintaining tail-risk protection against potential sharp downside moves.
