Vanguard has filed plans with the U.S. Securities and Exchange Commission to launch its most expensive exchange-traded funds (ETFs) to date, introducing active equity "Wellington" ETFs with fees ranging from 30 to 40 basis points. This move aims to strengthen Vanguard's actively managed ETF lineup. Meanwhile, BlackRock is expanding its investment portfolio with two notable initiatives. Its infrastructure fund, Global Infrastructure Partners (GIP), has agreed to acquire a 49.99% stake in Eni's carbon capture and storage (CCUS) business, although the financial terms were not disclosed. Additionally, BlackRock is preparing to launch a new fund focused on purchasing discounted venture capital stakes from other investors, entering the growing venture secondaries market where stakes typically trade at around 75% of net asset value. Separately, Baron Capital is considering entering the $12 trillion ETF industry after months of deliberation.
