BlackRock has launched a new exchange-traded fund (ETF) that extends beyond the 'Magnificent Seven' tech stocks, as reported by ETF Edge. This move comes amid significant changes in the ETF landscape, including State Street Global Advisors' recent filing to offer mutual fund share classes of its ETFs, which adds to a growing list of 34 firms now pursuing this strategy. Additionally, over $7 trillion in equity funds are expected to undergo a major reshuffling next year due to new FTSE Russell rules aimed at reducing the influence of the largest stocks on popular benchmarks. In a related development, Rob Arnott's firm, managing $147 billion, is betting on stocks recently removed from the S&P 500, anticipating substantial upside potential for these companies.
