BlackRock plans to introduce ETF share classes across five active mutual funds that collectively manage $55 billion in assets. The move expands investor access to established strategies through the more liquid and tax-efficient ETF structure without converting the underlying funds. This initiative follows a wave of mutual fund-to-ETF conversions and product launches across the industry, signaling accelerating momentum in the shift toward exchange-traded vehicles. BlackRock’s latest step adds significant scale to the trend as asset managers increasingly align offerings with growing demand for ETF wrappers.
