An overlay is a portfolio-management layer that adjusts exposures, hedges, or implementation without replacing the underlying manager lineup.
Overlay in portfolio management refers to a strategy where software is used to coordinate and optimize an investor’s multiple separately managed accounts (SMAs). This approach aims to prevent inefficiencies, ensure strategy alignment, and coordinate executions across various portfolios to meet the overall investment objectives.
Overlay strategies are crucial in asset management because they provide a holistic view of an investor’s portfolio, allowing for better risk management, tax efficiency, and alignment of investment strategies. Without an overlay, there’s a risk of conflicting strategies and redundant trades across different accounts.
Software applications play a vital role in implementing overlay strategies. These applications are designed to:
