Massari vs Koyfin
Massari combines customizable multi-pane charting layouts and macro dashboards with deep institutional intelligence: comprehensive Asset Analysis, an institutional portfolio risk engine (VaR, Expected Shortfall, CVaR, Kurtosis, Block Bootstrap), a proprietary multi-asset screener with factor metrics, Fund X-Ray (look-through, reverse ownership, overlap), decades of SEC filings with coordinate audit links, the Massari Excel Add-In, algorithmic forward estimates, and a broad range of native MCP tools.
The Core Friction with Koyfin
Retail charting tools aggregate third-party normalized data without primary filing coordinate audits, lack non-Gaussian portfolio risk analytics (Historical VaR, Expected Shortfall, CVaR 95/99%, Kurtosis), and do not offer public API or native Model Context Protocol (MCP) integrations for AI agents.
Workflow Pain Points & The Massari Solution
How Massari replaces manual friction, disconnected tooling, and compliance audit risk with source-linked intelligence:
Normalized metrics cannot be audited back to exact sentences in original SEC filings.
Decades of primary SEC Form 10-Ks/10-Qs with 1-click line coordinate audit trails.
Complete institutional audit integrity backing every valuation and model.
Basic portfolio charts lack non-Gaussian tail risk modeling and expected shortfall estimates.
Multi-layered Risk Engine: Historical VaR (95%), Parametric VaR (95%), Expected Shortfall, Skewness, Excess Kurtosis, CVaR 95/99%, Worst/Best Day extremes, Rolling Volatility vs SPY, and 5,000-path block bootstrap Monte Carlo.
Rigorous downside stress testing and audit-ready tail risk defense.
Standard ratio screeners lack proprietary yield sustainability and macro factor sensitivities.
Proprietary multi-asset screener with Distribution Sustainability, Factor R², and Insider flows across 19,000+ securities.
Uncover hidden structural risks and factor exposures before taking positions.
Basic Excel add-in only pulls static data without docked filing verification.
Massari Excel Add-In and Native Excel Export capability with company KPIs and docked audit panel in Excel.
Interactive valuation models with persistent source lineage directly in spreadsheets.
Limited portfolio tools lack reverse stock ownership lookups across funds.
