A Market Demo That Doesn’t Fake Its Backtests

Finn Forecasts is live — forecasting, portfolios, and risk behind a fast server-rendered UI. The parts I care about are the honest ones.

Rigor over polish:
walk-forward cross-validation (no future leakage) · transaction costs charged in the backtester
Plus FinBERT for finance-aware news sentiment, and first-class LATAM coverage — IPSA universe + Chilean macro + Banco Central de Chile.

A general sentiment model fumbles “missed guidance” vs “raised guidance”; FinBERT doesn’t. And rather than defaulting to US tickers, Finn covers the markets I actually live in. Live at finn.fasl-work.com — educational demo, not investment advice.
