Key Takeaways

  1. An Overlay is a stack of entries that can be managed independently, where each entry is entire app screen. It provides a way to overlay widgets onto another.
  2. Overlays are used extensively within Flutter. For example, the Navigator uses overlays to display routes, dialogs, dropdown menus and more.
  3. Multiple overlays can be layered on top of each other to create complex UI experiences. Each OverlayEntry defines a widget and whether the overlay should remain visible when the user interacts with the space outside the overlay.


Overlay is a critical term in business and finance as it refers to a management style that integrates various complex investment strategies into a portfolio, including strategies for specific investment goals, tax efficiencies, risk management, and overall portfolio optimization. It allows businesses or investors to manage their investment vehicles more effectively and comprehensively while retaining their desired exposure to specific asset classes or market sectors. By implementing a good overlay strategy, it can enhance returns, reduce risk, and simplify the implementation and ongoing management of the portfolio. Therefore, understanding and applying the concept of overlay can lead to better financial decision-making and improved outcomes.


Overlay as a financial term is generally used in the realm of asset management and portfolio strategy, particularly in the context of risk management. Its purpose is predominantly to refine or adjust an investment portfolio’s risk and return profiles to match a certain desired outcome in accord with the investor’s priorities. It aims to provide additional exposure to certain asset classes or hedge against certain types of risks, without changing the underlying portfolio. As such, an overlay strategy can be used to modify the geographic, interest rate, currency, or other exposures of a portfolio. This strategy is typically implemented through the use of financial derivatives like futures, options, and swaps. For example, an investor might use a currency overlay to hedge against foreign exchange risk in an international portfolio. By allowing for such fine-tuning, overlays provide investors with an added layer of control, enabling them to better align their portfolios with their risk tolerance, financial goals, and market outlook. It’s important to note that while effective in managing risk, overlays also come with their own set of complexities and challenges, necessitating careful management and monitoring.


1. Investment Overlay: In the world of finance, professional asset managers sometimes use an investment overlay strategy to manage a client’s exposure to various markets, sectors, and risk levels across different asset classes and investment accounts. For instance, a client may have several different stock and bond accounts, as well as real estate investments. The asset manager would use an overlay strategy to coordinate those investments so that the client’s overall portfolio matches their desired risk profile, investment goals, and tax considerations.2. Overlay in Portfolio Management: An example can be found in portfolio management where an asset manager may use an overlay strategy to gain exposure to certain asset classes or sectors without buying the underlying securities. For example, they might use derivative instruments such as futures or options to obtain exposure to commodities or global equity markets, effectively overlaying this exposure on top of the existing portfolio.3. Currency Overlay: Another real-world example of overlay is a currency overlay strategy, which is used by multinational corporations and large investment firms. In such a strategy, the companies aim to manage the risks associated with changing currency exchange rates. They hedge their exposure to foreign currencies with the aim of reducing the potential for loss due to fluctuating exchange rates. For instance, a U.S. company doing substantial business in Europe may use a currency overlay strategy to protect against the risk of the euro declining against the dollar.
