⚠️ Risk Factors


🏁 The Bottom Line

Real talk: This $6.7M diagonal spread tells us institutional money is betting on Vistra continuing its AI-powered rally but staying below $220 through November. The gamma data backs this up with massive resistance at that level.

If you own VST: Hold through earnings on November 5th - smart money is positioned for upside

If you're watching: The $195-$220 range is the battleground - buy dips to gamma support at $190-$195

If you're bullish: Consider following the institutional playbook with diagonal spreads or December calls

Mark your calendar: November 5th earnings will be the key catalyst - this spread is positioned to profit from a controlled rally into that event!
