Strategy notes
Consider calendar spreads into earnings for stocks with elevated front-month IV but muted longer-dated price risk. Target sectors: resources on positive demand signals.
Iron out theta decay with short iron condors on stable names where skew compresses post-news. Monitor early-week options open interest.
Buy protective puts for gamma risk around large macro events; consider staggered expiries to smooth premium exposure.
Option alerts & trade ideas (examples)
Large sweep of calls 45–50 suggests bullish flow; watch IV and consider short-dated call ratio as a hedge for directional exposure.
Concentrated put buying at 82–88; asymmetry favors selling iron butterflies in controlled size with predefined risk limits.
