Current Interpretation of S&P Options Structure To put it simply, here’s what to watch for S&P tomorrow. Looking at the overnight session, SPY’s price is roughly stuck between 7500 and 7550. This range is suppressing the short-term support from put options. On the upside, the 7600 to 7700 range is a key level where a massive amount of calls across all expirations are concentrated. This explains why the market has been grinding at this level and struggling to break out effectively. On the downside, 7300 is a strong support zone that’s relatively far from the current price. Market makers have significant support there, but for now, we don’t need to focus on 7300—it’s unlikely to be reached in the short term. Still, it’s worth pointing out this put wall. The most critical level right now is the 7500 put wall. If the bulls lose 7500 and drop below 7480 during regular trading hours, the market will officially enter the danger zone of negative Gamma. Once in negative Gamma, market makers’ hedging direction completely flips—they’ll sell more as prices drop, amplifying the downward momentum, and volatility will spike rapidly. So, the most important thing to watch at tomorrow’s open is whether 7500 can hold. If it holds, the positive Gamma support mechanism remains intact, and pullbacks will be manageable. If it breaks, volatility will surge, and it’ll be time to switch strategies.
