Types of Stock Alerts You Need
Most investors only set price alerts (e.g., "Notify me if Apple drops below $150"). However, to truly protect your portfolio, you need more sophisticated monitoring:
- Price Alerts: Simple target prices or percentage moves.
- Volatility Alerts: Notifications when a stock's volatility (IV) spikes, indicating potential turbulence.
- News Alerts: Real-time updates on earnings, mergers, or regulatory changes.
- Portfolio Risk Alerts: (Crucial) Alerts when your portfolio becomes too concentrated or correlated—a feature unique to advanced tools like Guardfolio.
đź’ˇ Key Insight: A price alert tells you after the damage is done. A risk alert tells you before a crash happens.
