Investment trusts, also known as closed-end funds, are companies listed on a stock exchange that invest in a portfolio of assets on behalf of their shareholders. As actively managed investment vehicles, investment trusts allow portfolio managers flexibility to pursue returns while providing investors exposure to a diverse range of assets. The global investment trusts sector has seen rapid growth in recent years, led by several key players who manage billion-dollar portfolios spanning various geographic regions and asset classes. This article will analyze the major global investment trusts by assets under management and summarize their investment strategies and portfolios.

Scottish Mortgage Investment Trust is the largest investment trust globally with £16 billion under management
Scottish Mortgage Investment Trust, managed by Baillie Gifford, is the largest investment trust in the world with over £16 billion ($19 billion) of assets under management as of September 2022. Launched in 1909, it invests globally in a concentrated portfolio of publicly listed and private companies across sectors including technology, healthcare and consumer brands. Scottish Mortgage aims to identify and invest in high-growth companies, with significant holdings in U.S. tech giants such as Tesla, Amazon and Netflix. It has achieved strong returns driven by its growth-oriented strategy.

RIT Capital Partners invests in both public and private markets with £4.1 billion under management
Founded in 1961, RIT Capital Partners manages £4.1 billion for an international shareholder base. With a total return approach, it invests across listed equities, private equity, hedge funds, credit and absolute return strategies.
