Strategies for Managing Volatility
1. Maintain a Long-term Perspective
Historical data shows that markets tend to recover from downturns over time. Focus on your long-term goals rather than short-term fluctuations.
2. Continue Dollar-Cost Averaging
Regular investing helps smooth out market volatility by purchasing more shares when prices are low and fewer when prices are high.
3. Stay Diversified
Index funds provide built-in diversification, which helps reduce the impact of volatility on your overall portfolio.
