[Two Index Trading Teams Under Millennium Earn Approximately $3.7 Billion in a Single Month] According to Bloomberg, two teams under the hedge fund Millennium Management, specializing in index rebalancing trades, earned a combined profit of approximately $3.7 billion in June, accounting for more than half of the fund's $6.6 billion pre-tax profit for the month. The two teams, led by Glen Scheinberg (New York) and Pratik Madhvani (Dubai), primarily leveraged high-risk positions in index rebalancing, betting on the inclusion and exclusion of constituent stocks. Events in June such as the S&P 500 quarterly rebalancing, Nasdaq 100 quarterly changes, Russell annual reconstitution, SpaceX's "fast-track inclusion," and multi-asset end-of-quarter rebalancing provided concentrated trading opportunities, driving Millennium's June return to 4.1% and raising its year-to-date cumulative return to 10.5%.
