A portfolio is considered “cost-efficient” when it minimizes expenses such as fees, taxes, and transaction costs, allowing you to keep more of your investment returns. On the other hand, a “high-quality” portfolio comprises well-diversified assets, often including a mix of stocks, bonds, and other investments that align with your financial goals. Such a portfolio aims for stable growth and risk management. Combining cost-efficiency and high-quality assets helps ensure your investments are as optimized as possible for long-term success.
