Yes. A robust, free portfolio tracker can help you maintain a well-diversified portfolio. The key principle of sound long-term investing is to diversify risk across a well-balanced portfolio. Long-term investors should avoid holding positions that are disproportionately large compared to your total portfolio, as a major setback in one investment could lead to significant losses. Effective risk management involves keeping individual positions in check and ensuring a balanced asset allocation across different sectors and industries. While prioritizing growth sectors can be appealing, concentrating too heavily in a single industry can expose your portfolio to unnecessary risk.
