# Gyre Research — Full LLM Context > Extended context file for LLMs indexing this site. If you're a crawler, start with /llms.txt for the structured short version; this file contains fuller inlined content. --- ## WHAT THIS IS Gyre Research (legal entity Gyre Holdings LLC) is a cloud-based portfolio analytics platform for investment managers. One calculation engine feeds 55 interactive reports spanning performance, risk, compliance, accounting, and seven other disciplines. Every report is clickable from any aggregate down to the source transaction, auditable to the calculation step that produced it, and answerable in plain English via a portfolio-native LLM. The product replaces the patchwork of vendors typical investment managers run (one system for performance, another for risk, another for compliance, another for accounting) with a single unified platform that shares one data layer and one calculation engine across every view. --- ## WHO IT'S FOR - Portfolio managers at hedge funds, family offices, RIAs, and institutional asset managers - Investment analysts supporting those PMs - Operations and middle-office teams at the same firms Not consumer investors, not retail traders. --- ## THE 11 PLATFORM CATEGORIES ### 1. Data Institutional-grade reference layer. Security master (identifiers, classification, lifecycle), point-in-time price history across every covered market with full corporate-action adjustments, benchmark constituents and returns for standard indices and custom blends, market calendar with exchange holidays and settlement conventions, corporate-action ledger (splits, dividends, spin-offs, M&A), company fundamentals, SEC filings, streaming company news with relevance tagging, live reference-data quality monitor with automated anomaly detection. ### 2. Portfolio Management Operational spine. Trade lifecycle and STP with per-counterparty STP/break rate tracking, multi-currency cash balance (settled + unsettled) and forward-looking forecast, corporate-action cash ledger, investor-level capital activity (subscriptions, redemptions, NAV strike), cross-prime-broker margin and collateral tracking. ### 3. Portfolio Construction Build-and-rebalance workflow. Custom benchmark blends with constituent-level comparison, security-level and segment-level rebalance with turnover budgets, delta-adjusted multi-asset exposure sizing, cash-aware allocation, mandate-compliant rebalance proposals pre-checked against restricted lists. ### 4. Back Testing Historical simulation workbench. Event-driven simulator with point-in-time data (zero look-ahead), survivorship-bias-free universe, configurable transaction-cost and market-impact models (linear, square-root, Almgren-Chriss). Simulated runs feed the same live Performance and Risk reports for directly comparable metrics. ### 5. Performance Return calculation. Daily Time-Weighted Return (TWR) via geometric linking across all standard periods (daily, WTD, MTD, QTD, YTD, 1Y, 3Y, 5Y, since-inception). Money-Weighted Return (MWR / IRR) for capital-call vehicles. Dollar P&L decomposed into price/income/FX/realized/total with top-bottom contributors. Brinson-Hood-Beebower attribution with Cariño multi-period linking. Fully GIPS 2020–compliant composite presentation with every §1.A disclosure, GIPS Performance KPI (3-year annualized standard deviation per §1.A.12, Sharpe, max drawdown, CAGR), GIPS Return Decomposition at position-month level with provision-reference annotations. ### 6. Risk Multi-factor risk analytics. Covariance / correlation with sample, EWMA, Ledoit-Wolf shrinkage, and factor-model estimation. Portfolio and position-level risk stats. Custom betas including asymmetric up/down (β⁺/β⁻). Historical and parametric VaR with full decomposition. Scenario-based stress tests (2008 GFC, 2020 COVID, custom). Exposure concentration (HHI, tail metrics). Proposed hedge ratios. ### 7. Compliance Audit-ready rule engine. 50 configurable rules across 6 categories (concentration, sector, credit, liquidity, counterparty, mandate). Three check modes: pre-trade (called by allocator dozens of times per block), post-trade (immediately after execution), end-of-day (full-portfolio scan). Immutable evaluation log per check. ### 8. Reconciliation Back-office automation. LLM document parsing extracts structured fields from unstructured custodian statements, corporate-action notices, and prospectus supplements. Continuous position, transaction, and cash reconciliation across custodians, prime brokers, and the internal PMS. ### 9. Portfolio Accounting Books of record. Double-entry general ledger with 20 event-to-journal mappings. Daily accruals including OID accretion per IRC §1272, market-discount amortization, bond-premium amortization, IFRS 9 ECL 3-stage impairment. Fee calculation with high-water-mark and hurdle rate. Formal P&L statement, trial-balance tie-out, audit-ready multi-class NAV. ### 10. ESG Mandate-aware ESG oversight. Multi-provider weighted-average scores at portfolio, strategy, and sleeve level. Exclusion screens with revenue-threshold and values-based overlays. LLM-derived ratings with traceable evidence for issuers lacking third-party coverage. ### 11. Tax Enterprise tax-lot engine. Nine lot-relief methods (FIFO, LIFO, HIFO, specific identification, plus tax-optimization variants). IRC §1091 wash-sale disallowance with cross-account and cascading detection. §1256 mark-to-market handling, PFIC detection, straddle recognition. AI-ranked loss-harvesting prioritizing after-tax impact conditioned on account tax status, carryforwards, and wash-sale history. --- ## THE RESEARCH LIBRARY 286 curated documents on quant finance, risk management, machine learning, AI, economics, public policy, international relations, trade, and programming.
