Frequently Asked Questions
ERA US (Equity Research Assistant) is an institutional-grade S&P 500 analytics platform. It provides rigorous intrinsic value estimates — DCF, DDM, EV/EBITDA, P/E, P/B — for all 503 S&P 500 companies, backed by 30+ years of price history and up to 10 years of fundamentals.
ERA uses a multi-model agentic approach. It classifies your company (growth, mature, cyclical, financial, etc.), selects the most appropriate valuation models, then runs each model step-by-step with a live chain-of-thought. Inputs include revenue CAGR, FCF history, blended beta (Blume + Damodaran), WACC, sector benchmarks, and macro data (10-yr Treasury, ERP). A weighted consensus IV is produced from whichever models apply.
Price history (2000–present) and fundamentals (up to 5 fiscal years) are sourced from public market data providers. Macro data covers Fed Funds Rate, CPI, GDP, VIX, and the Yield Curve. Sector benchmarks and beta priors are derived from published academic datasets. All data is stored and processed locally — nothing is sent to external servers.
Price data is refreshed incrementally — only missing dates are fetched. Fundamentals are updated after quarterly earnings seasons. The dashboard displays a stale-data banner when price data is more than 3 days behind.
No. ERA is a research and analysis tool. Intrinsic value estimates are quantitative models based on historical data and specific assumptions — they are starting points for your own due diligence, not financial advice. Markets can deviate from intrinsic value for extended periods. Always do your own research before investing.
ERA Chat is an AI-powered market advisor. Once you load a stock, ERA Chat has full context — price trend, EPS trajectory, valuation models, sector comparison, macro conditions — and you can ask follow-up questions in natural language. It's like having a portfolio analyst on call.
All 503 S&P 500 constituents. Fundamentals are available for virtually all companies. A small number of recently-added constituents or special-class shares may have limited historical data.
