Addressing common investment challenges

Balancing investor risks, returns and reputational requirements, has become an increasingly complex challenge. Investors need to be in a position to make efficient decisions. They therefore need access to the right expertise and resources. That’s why many investors are looking externally for strategic portfolio management advice, access to manager research and support with asset allocation and day-to-day operations.

Investors are using outsourced investment solutions to address a range of common challenges. These include cost pressures, operational inefficiencies, resource constraints, regulatory changes, manager sourcing, accessing private market opportunities, integrating environmental, social and governance (ESG) issues into portfolios, and impact investing.

More and more investors are recognising the benefits of collaborating with external and unbiased financial service providers. However, some reservations and myths remain. These are addressed below.

Key considerations for institutional investors

Demands and challenges for portfolio managers are intensifying. Pressure is growing to explore new opportunities and pursue compelling returns. We have identified three key considerations to help you position your portfolio for success.

Experience has shown us that precise and intuitive portfolio governance and due diligence are key. They will help to give you the confidence that your investments are meeting your needs, and that your asset allocation has been tested under multiple scenarios.

Investors are incorporating ESG considerations into portfolios. They are also turning their attention to diversity, equity and inclusion (DEI) issues, in relation to both managers and strategies. They are seeking to strike a balance between doing the right thing and delivering on investment commitments. This is otherwise known as impact-investing. We work with clients to meet this challenge and to find an optimal balance that will best meet their needs.

Alternative investments provide an opportunity to guard against the volatility of equities, hedge against inflation, and achieve better returns. Hedge funds can provide a great way to diversify out of equities without sacrificing returns. Private equity investments aim to attain a significantly higher rate of return than publicly traded equities. Real assets, such as infrastructure and real estate, can provide similar benefits alongside a measure of protection against inflation. Our global scale and resources can help you access all types of alternative investments, tailored to your needs and at competitive fee levels.

Three steps for optimising your investment process

Your investment strategy and oversight processes should support your investment goals. There are three stages to consider as part of this review.
  1. Review and adapt your governance framework
    It is vital to keep your portfolio on track. If you need to improve your governance operating model, our investment solutions can provide the support you require, both now and in the future.
  2. Assess your portfolio against your future objectives
    Understanding how investments are performing takes vigilance. Investors must also search for new opportunities in order to future-proof their portfolios. We can help you have confidence that your investment strategy reflects your risk, return and reputational requirements.
  3. Test your ability to adapt and respond to market movements
    You need to be in a position to rebalance your portfolio quickly and effectively if you are faced with market volatility. We can help you install optimised decision-making processes. These will ensure your portfolio is responsive and aligned to your outcome requirements.
