Entry Level (Learning Mode)
Start small, focus on education, build experience
Recommended Starting Points:
Why this approach: Options amplify both gains AND losses. AVGO's $402M bet is a 3-leg diagonal - complex for beginners. Start by understanding why institutions use these structures before replicating.
Critical rules for beginners:
- Never risk more than 1% of portfolio per trade
- Don't trade AVGO earnings week until you've watched 10+ cycles
- Avoid VTYX biotech binary - too speculative for new traders
- If you don't understand delta/theta/vega, study before trading

The Bottom Line: AI Infrastructure Leads $639M Year-End Positioning Wave
This is institutions making their final 2025 bets. $639 million concentrated across AI infrastructure ($485M AVGO + CRWV), crypto momentum ($92M COIN + HOOD), and strategic healthcare positioning ($16.2M MRK + VTYX). The unified theme: conviction on AI infrastructure as the decade's defining investment thesis, crypto as institutional-grade asset class, and selective healthcare catalyst plays.
The biggest questions:
Your move: This concentrated positioning on AI infrastructure and crypto suggests institutions with strong year-end conviction. Follow the themes that align with your thesis - but remember these are sophisticated multi-leg strategies that may be part of larger portfolios we cannot see.
Risk reminder: Don't blindly copy institutional trades. These $639M in positions come from sophisticated players with risk management we cannot observe. Position size appropriately, use stop losses, and never risk more than you can afford to lose.

Options involve substantial risk and are not suitable for all investors. The unusual activity tracked here represents sophisticated institutional strategies that may be part of larger hedged portfolios not visible to retail traders. These positions represent past institutional behavior and don't guarantee future performance. AVGO's $402M bet ahead of December 12 earnings is particularly high-stakes given binary earnings outcome. Always practice proper risk management and never risk more than you can afford to lose completely. Entry level investors should paper trade extensively before committing real capital. Options can expire worthless, resulting in 100% loss of premium paid.
