When invested by manager in a diversity of stocks?

When a manager invests in a diverse array of stocks, the goal is to spread risk across different sectors and industries, reducing the impact of poor performance from any single investment. This diversification can lead to more stable returns over time, as gains in some areas may offset losses in others. Additionally, it allows the manager to capitalize on various market opportunities, potentially enhancing overall portfolio performance. Ultimately, a well-diversified portfolio can help achieve long-term investment objectives while mitigating volatility.
