Microsoft Reversal at Key Gamma Resistance Delivers Profit Using a Structured Options Spread

Options positioning often reveals where volatility and directional momentum can emerge, especially around key Gamma levels. In this case study from 18-21 November 2025, Microsoft (MSFT) provided a textbook example of how SpotGamma tools can help traders identify resistance, confirm options flow, and structure a trade with controlled risk.

When Microsoft gapped down and briefly rallied back toward the $500 Key Gamma Strike, the move quickly stalled. As traders began selling calls, the HIRO indicator showed increasing bearish positioning, suggesting the rally was likely to reverse.

By combining SpotGamma’s key levels, real-time options flow signals, and the Options Calculator to model the trade, SpotGamma contributor Doug Pless was able to structure a defined-risk position that produced a $374 profit over four days.
