BlackRock, State Street Target Invesco’s $379 Billion Tech Grip

Wall Street’s biggest ETF issuers are circling Invesco Ltd.’s Nasdaq 100 franchise, threatening to end its near-exclusive hold on the index.

Just a day after BlackRock Inc. filed a challenger to Invesco’s Nasdaq 100-tracking ETF, State Street Corp. followed suit. On Tuesday, it submitted paperwork to launch the State Street SPDR Nasdaq 100 ETF, which would be its first fund focused on the tech-heavy gauge.
