Jane Street increased its holdings in Strategy shares by 53.8% to 4.119 million shares

According to Bitcoin Magazine, trading giant Jane Street Group increased its holdings in MicroStrategy (MSTR) by 53.8% in the third quarter, bringing the total to 4,119,097 shares. The 13F filing submitted on Thursday shows that this position as of September 30 increased by 1,441,475 shares from the 2,677,622 shares disclosed on June 30, when the position was valued at $232.8 million. Based on the price of $153.09 per share on September 30, the newly added position is valued at $630.6 million; however, based on Thursday's closing price of $114.41, the same position is valued at approximately $471 million.

The filing also lists call options covering 13,573,000 shares of MicroStrategy and put options covering 13,991,800 shares, both of which are more than three times the size of the common stock holdings, with the former valued at $2.08 billion and the latter at $2.14 billion. Since Jane Street is a major market maker in stocks, ETFs, and options, part of the common stock holdings may be hedges against options and market-making books, and the 13F filing does not specify the exact ratio. The report consolidates the holdings of seven managers, including Jane Street Capital, Jane Street Options, and Jane Street Global Trading, listing a total of 14,764 records with a total value of $1.19 trillion.

In the 13F submitted on Thursday morning, Jane Street's increase was the highest among large MicroStrategy holdings. Capital International Investors increased its holdings by 4.5% to 36,467,109 shares, valued at approximately $4.17 billion based on Thursday's closing price; Invesco increased its holdings by 10.9% to 10,362,698 shares; Renaissance Technologies reduced its holdings by 41% to 1,515,560 shares and completely liquidated its previously disclosed spot Bitcoin ETF position. The above data is as of September 30, prior to MSCI's decision to remove MicroStrategy from its U.S. index, a change that will force index funds to sell before November 30.
