Comprehensive SEC 13F Analysis: Maven Securities LTD
1. Portfolio Overview

Maven Securities LTD manages a substantial portfolio valued at approximately $4.05 billion as of September 30, 2025. The portfolio is highly diversified, comprising 465 individual holdings. However, the filing reveals a unique structural characteristic: a massive portion of the portfolio ($2.14 billion, or roughly 53%) is categorized as "Unknown," with a relatively small explicit allocation to ETFs ($147...

The firm experienced a slight contraction in assets under management (AUM) this quarter, with the total portfolio value decreasing by 3.7% (from $4.20B to $4.05B). This decline occurred alongside a high-turnover strategy characterized by significant rotation: the firm executed 22 new buys and 22 complete exits, with zero positions remaining unchanged in the top activity summary. This indicates an actively managed approach with rapid capital redeployment rather than a static buy-and-hold strategy.

2. Key Holdings

The portfolio's top 50 holdings reveal a heavy reliance on Exchange Traded Funds (ETFs) for liquidity and broad market exposure, mixed with concentrated positions in specific blue-chip stocks.
