Cboe's Volatility Surge: A Bullish Market With a Bearish Hedge?

The June 2025 trading volume report from Cboe Global Markets reveals a market in flux—equity investors are placing big bets, but hedging with volatility tools like never before. Let's dissect the numbers to uncover what this means for traders and investors.

The Data: A Record-Breaking Month for Options, Especially Volatility-Linked Contracts

Cboe's S&P 500 (SPX) options hit a new monthly average daily volume (ADV) record of 3.7 million contracts, with zero-days-to-expiry (0DTE) SPX options soaring to 2.2 million ADV—both all-time highs. Mini-SPX (XSP) options also set quarterly records, with ADV up 100% year-over-year. These contracts, often used in volatility trading strategies, suggest investors are chasing short-term opportunities while hedging risks.

Meanwhile, index options ADV rose 18.6% year-over-year, driven by SPX's dominance. Even the futures market, which typically serves institutional hedgers, saw a 21% drop in ADV, indicating a shift toward equity-linked options for flexibility.

What's Driving This Surge? A Bullish Market with a Bearish Undercurrent

The sheer volume of SPX/XSP activity points to two key forces:
1. Optimism: Equity markets are thriving, as evidenced by the 23% YTD growth in multiply-listed options (which track broader market activity). Investors are buying calls or selling puts, betting on continued gains.
2. Caution: The spike in 0DTE contracts—a tool popular with day traders and hedgers—hints at underlying anxiety. Traders might be speculating on short-term volatility while protecting long-term equity positions.

The rise in index options RPC (revenue per contract) to $0.923 also matters: it suggests Cboe is capturing more value from these trades, likely due to higher fees on volatility-heavy contracts. This signals institutional and retail traders are willing to pay premiums for hedging tools, further validating the “bullish but nervous” narrative.

Volatility Products: The Silent Catalyst

While Cboe doesn't explicitly report VIX-linked product volumes, the SPX/XSP frenzy is inextricably tied to the Cboe Volatility Index (VIX). Here's why:
- VIX Futures/Options: SPX options are the primary instrument for calculating the VIX. High SPX volumes imply traders are pricing in elevated volatility expectations.
- ETF Play: The VIX's rise (even if modest) could drive demand for long volatility ETFs like VIXY or UVIX, which profit from volatility spikes. Conversely, short volatility ETFs (e.g., SVXY) might underperform if the VIX remains elevated.

Actionable Strategies for Investors

1. Equity Bulls with a Hedge:
2. Buy SPY or VOO to capitalize on the S&P 500's momentum.

3. Pair with a long volatility position: Allocate 5-10% of your portfolio to VIXY to hedge against sudden dips.

4. Volatility Arbitrageurs:

5. Short SPX/XSP 0DTE contracts if you believe the market's nervousness is overdone. These contracts decay rapidly, offering a high-reward, high-risk trade.

6. Sector Rotations:

7. Tech and Consumer Discretionary: If equities continue their rally, these growth-heavy sectors (e.g., AAPL, AMZN) benefit most.
8. Utilities or REITs: For conservative investors, these defensive sectors (e.g., XLU, XLRE) offer stability if volatility spikes.

Risks and Red Flags

• Futures Decline: The 21% drop in futures ADV might signal a shift toward less liquid instruments, increasing market fragility during crises.
• RPC Volatility: Cboe's preliminary RPC figures for options are still below their 2024 peaks, suggesting pricing pressures if volume growth slows.

Final Take

Cboe's June report paints a market that's both bold and cautious: equity investors are buying aggressively, but hedging like it's 2008. Traders should lean bullish on equities but pair exposure with volatility tools. For now, SPY + VIXY is a balanced bet—unless the VIX suddenly soars, in which case, prepare for a pullback.

Stay nimble, and keep an eye on CBOE's Q2 RPC finalization—it could confirm whether this surge is a trend or a blip.
