Financial Impact Assessment

Impact Evaluation

• Nature of Filing: This filing details the holdings of SEI Investments as an asset manager, not transactions by corporate insiders in SEI's own stock. Therefore, metrics like 'Transaction Value % of Market Cap' are not applicable.
• Portfolio Scope: The reported value of ~$93 billion across over 5,600 positions highlights SEI's role as a large, highly diversified institutional manager. The portfolio includes positions managed by its subsidiaries, such as SEI Investments Management Corporation.
• Significance: For a large-cap company like SEI ($10.16B market cap), a 13F filing is a routine operational disclosure. Its significance is primarily for tracking long-term allocation trends rather than signaling short-term market moves.

Market Impact Analysis

Stock Impact Prediction

• Direction: Neutral
• Reasoning: This is a standard, legally required disclosure of portfolio holdings as of a past date (September 30, 2025). It does not represent new, material information about the filer's own financial performance or any specific insider action that would typically influence its stock price.

Volume & Sentiment

• Expected Volume Impact: Negligible. The market anticipates these routine filings from large asset managers.
• Sentiment Indicator: Neutral. The filing reflects a diversified, broad-market strategy consistent with a large institutional manager and does not indicate a specific bullish or bearish stance on any single security or the market as a whole.

Additional Context

Transaction Notes

• Filing Type: This is a holding report, not a transaction report. The data reflects positions held on a specific date, not the buy/sell activity that led to them.
• Timing: The data is as of September 30, 2025, and was filed on November 13, 2025, making it a lagging indicator of the firm's current portfolio.
