Public ownership research

Hedge fund 13F holdings and investor portfolios

Follow the latest public holdings for technology and AI-focused managers, including Situational Awareness LP, Altimeter Capital, Coatue Management, Atreides Management, and Value Aligned Research Advisors (VARA). Inspect each Form 13F report, notice, amendment, and source filing, then compare disclosed portfolio composition with Hallucination Yield model sentiment when a security identity has been reviewed.

Form 13F is generally filed after quarter end. It does not show a current portfolio, short positions, complete derivatives exposure, fund NAV, or every security. This is research data—not investment advice.
