ETF exposure: QQQ for tech, XLK for infrastructure without single-stock risk
Share positions: ORCL shares for AI infrastructure exposure
Education focus: Study collar strategies from JD, calendar spreads from OKLO

⚠️ Risk Management for All Types

Essential Rules:

Position sizing is critical - Never risk more than allocation limits above
AI infrastructure momentum - Can reverse quickly, set 25% stop losses
Catalyst timing - September 30 and October 1 are key binary events
Nuclear sector volatility - OKLO can move 20%+ on policy news
Biotech binary risk - Phase 3 trials can gap 50%+ either direction

AI Infrastructure Warning: Today's $490M inflow suggests infrastructure phase of AI revolution beginning. Unlike bubble stocks, these are picks-and-shovels plays with real revenue models. However, execution risk remains high - Oracle's CloudWorld and AppLovin's platform launch are make-or-break catalysts.

Patience Emphasis: Don't chase momentum immediately. Many of these positions are September 30 - October 31 catalyst plays. Wait for pullbacks unless you're taking small catalyst exposure. The infrastructure theme has multi-quarter duration.

Nuclear Power Special Note: OKLO's $70M calendar spread suggests sophisticated volatility play around regulatory catalysts. Nuclear stocks can move violently on policy news - understand the regulatory timeline before positioning.

Entry Level Critical: This infrastructure rotation requires understanding complex catalysts and regulatory factors. Start with broad infrastructure ETFs, practice with paper trading, and focus on learning institutional positioning patterns. Avoid YOLO plays until you understand the catalyst timelines.

⚠️ Options involve substantial risk and are not suitable for all investors. These institutional trades represent sophisticated strategies that may be part of larger hedged positions not visible to retail traders. The unusual activity represents past positioning and doesn't guarantee future performance. Nuclear and biotech sectors carry additional regulatory and clinical trial risks. Always practice proper risk management and never risk more than you can afford to lose. The AI infrastructure theme requires long-term perspective and patience - don't blindly follow unusual activity without understanding the underlying catalysts.
