S&P 500 Rises 0.6% at Midday on Easing Middle East Tensions
Options traders say a drop below 7,500 could turn dealer hedging into a source of selling and intensify volatility.
Traders are monitoring the 7,500 level as market positioning shifts, with data from SpotGamma, Barchart, and Cboe LiveVol showing this area acts as a key support guardrail that may no longer provide consistent dip-buying.
Market makers supply liquidity by balancing Options positions, but evidence suggests dealers were likely "long gamma" for weeks before the Stock moved away from their comfort zone, causing positive gamma to flip negative.
Brent Kochuba, founder of SpotGamma, wrote Thursday that positive gamma has lessened and the Stock has fallen below a "risk pivot," while the State Street SPDR SPY remains critical below 740.
"We are in a negative gamma regime," said Brendan Herbert, options product manager at Barchart. If the index drops, market makers must sell to cover deltas, potentially amplifying downward moves.
Investors sold Big Tech stocks as the Treasury yield touched 4.7%, the highest since January 2025, while Crude rallied. This broader market pressure adds uncertainty to the Stock market's near-term stability.
