For over 50 years, financial services companies have leveraged mathematical optimization to build portfolios that minimize risks while maximizing returns for clients.
By applying portfolio optimization, financial professionals can make data-driven decisions that are both strategic and compliant with the many complex regulations that govern financial activities—resulting in portfolios that are optimized for returns and resilient against market fluctuations.
A solver that employs advanced mixed-integer programming (MIP) technology can enhance this process even further, allowing investors to easily process large datasets, detect patterns, and develop investment strategies that align with their long-term financial objectives.Â
As its name suggests, portfolio optimization is the process of selecting an optimal mix of financial portfolio assets—such as stocks, bonds, or other investments—to achieve a specific objective. Typically, the goal is to maximize returns while minimizing risk. Â
At its core, this process involves making data-driven decisions to efficiently allocate capital under a specified set of constraints. These often include budget limits, regulatory requirements, and risk tolerance.Â
In practical terms, portfolio optimization helps investors and institutions answer complex questions like:Â
Mathematical models—especially those based on optimization techniques like MIP—allow asset managers to evaluate trade-offs between risk and return, incorporate real-world constraints, and uncover the most effective strategies with the flexibility to handle realistic and complex investment scenarios that traditional approaches often cannot address.Â
Portfolio optimization involves balancing expected returns against risks, while also considering the unique constraints and objectives of individual investors.
It’s a delicate task—one that requires portfolio managers to rely heavily on historical simulations and test complex strategies. These challenges demand a solver that can rapidly handle millions of ‘what-if’ scenarios, especially when dealing with highly compressed time series data.
Firms that can efficiently test a wide range of datasets and optimize scenarios in a short time have a distinct edge, as they can iterate more quickly and gain a competitive advantage in production.
MIP can support a wide range of practical constraints, which would be challenging (if not impossible) to model using traditional linear programming techniques.
Here are several examples of how MIP solving facilitates more robust portfolio optimization:
With Gurobi’s MIP technology, portfolio managers can incorporate discrete decisions in their portfolio selection. This includes many of the examples listed above, such as cardinality constraints on the number of asset allocations, or the consideration of transaction costs—leading to strategic insights that would be difficult to obtain through traditional portfolio optimization methods alone.
Companies from OneChronos to Robeco, swissQuant, and many others use Gurobi’s technology to tackle complex portfolio optimization problems with precision and ease, enabling the construction of investment portfolios that are both cost-effective and high-performing.
For example, swissQuant needed powerful and efficient algorithms to calculate optimal portfolios and ensure timely results that both their customers and banks could have confidence. Â
They used Gurobi to build an application that creates customer profiles, then identifies several optimal investment strategies for those profiles, along with the associated risks and benefits of each strategy—leading to a 1% higher return for customers. Â
Gurobi is already the solver of choice for many of the world’s leading financial institutions.
Now, with the introduction of our Gurobi Finance technical documentation, finance professionals can find dedicated resources to help them successfully leverage our MIP technology for advanced portfolio optimization.
