The stock market faces a delicate moment as multiple pressures converge: crude oil is climbing, bonds are selling off, and Big Tech shares have retreated following earnings reports. The 10-year Treasury yield recently touched 4.7%, marking its highest level since January 2025.
Despite these headwinds, the S&P 500 remains less than 3% below its record high and trades above last month’s lows, sitting at levels first reached in May. The setup bears resemblance to conditions seen in March, which preceded a monthlong selloff as geopolitical tensions surrounding Iran exceeded market expectations.
The Gamma Positioning Question
Options traders are closely monitoring the behavior of market makers—the institutional traders who provide liquidity by continuously buying and selling securities. According to analysis from SpotGamma, Barchart, and Cboe LiveVol, these dealers have maintained significant positioning around the 7,500 level in the S&P 500.
For at least a month leading into this week, evidence suggested market makers were “long gamma,” meaning they held options that benefit from volatility. In this configuration, their hedging activities naturally stabilize markets: when prices fall, they buy stock to balance their put options; when prices rise, they sell stock to offset their call positions. This dynamic has helped keep the S&P 500 largely confined to a 200-point trading range since mid-May.
When Support Becomes Resistance
The challenge now is that positive gamma positioning can flip negative if the index moves too far from dealers’ comfort zone. According to Barchart’s volatility model, that critical inflection point sits at 7,500. Below this threshold, market makers may need to sell rather than buy into weakness, potentially amplifying downward moves instead of cushioning them.
“We are in a negative gamma regime,” explained Brendan Herbert, options product manager at Barchart. “If we drop, market makers are going to have to sell to cover deltas so they could in theory make a downward move more intense.”
For the State Street SPDR S&P 500 ETF Trust, which tracks the index, the key watch level translates to roughly 740. A sustained break below that point could heighten the risk of accelerated selling.
Diverging Views on Downside Risk
Not all options analysts see immediate danger. Brent Kochuba, founder of SpotGamma, noted in a client communication Thursday morning that while positive gamma in the market has diminished, there remains “a fairly light amount of positive gamma” extending down to the 7,300 level.
Still, Kochuba acknowledged that the S&P 500 has dropped below what he termed a “risk pivot” and said he would be adding short-dated, out-of-the-money put butterfly spreads with a bearish directional tilt—a positioning that profits from moderate downside moves while limiting upfront cost.
The current environment leaves traders watching whether institutional hedging flows will continue to provide a safety net or whether the market has entered a regime where dealer positioning exacerbates rather than dampens price swings. With the index testing levels that have acted as guardrails for weeks, the answer may come soon.
