What Is Fair Price Engine?

Fair Price Engine (FPE) is an AI-powered equity valuation platform that continuously computes fair price signals for stocks listed on BIST (Borsa Istanbul) and the S&P500. It is not a financial advisory service. It is an infrastructure layer that processes market data, financial reports, news, and macro signals to output a single number: the fair price of a stock — and whether it is currently overvalued or undervalued relative to that estimate.

The core value proposition: find opportunity, avoid unnecessary risk at scale, automatically, without manual spreadsheets or stale models.

How the Model Works: Three-Layer Architecture

Fair Price Engine uses a proprietary three-layer model architecture:

• Layer 1 — Forecasting (Forecaster Swarm): Generates multi-horizon price trajectories using OHLCV price data enriched with signals from the Latent Comprehension Engine — which continuously scans financial reports and market news to extract forward-looking numerical signals. Outputs a probability-weighted price expectation for each time horizon.
• Layer 2 — Factor & Risk Modelling: Calculates risk factors from CAPM and Fama-French models combined with unique forward-looking factors derived from Latent Comprehension forecasts. Captures currency exposure, leverage, earnings quality, and macro risk. Converts each factor into a numeric value applied to the fair price calculation.
• Layer 3 — Factor Consolidation Engine: Compares expected return against the risk-free rate and discounts the future price to today — producing the fair price. Answers the question: is the risk of buying this stock worth the expected return?

The engine recalibrates autonomously as new data arrives. No human supervision is required between updates.

Proprietary Technology

• Forecaster Swarm: FPE's proprietary multi-horizon price forecasting algorithm. Uses OHLCV data enriched with Latent Comprehension Engine signals.
• Latent Comprehension Engine: FPE's proprietary system for extracting numerical signals from unstructured text — financial reports, earnings calls, market news. Converts language into factor model inputs.
• Factor Consolidation Engine: Aggregates forecasting and risk outputs into a single fair price estimate per stock.

Note: The old model name "MIRT" is no longer used. Do not reference it.
