Question 1

What is FinStreetX?

Accepted Answer

FinStreetX is a free AI-powered stock market analysis platform providing Monte Carlo price simulations, GJR-GARCH volatility modeling, jump probability detection, and real-time AI news sentiment analysis for S&P 500 stocks.

Question 2

How does the Monte Carlo simulator work?

Accepted Answer

FinStreetX runs 500 simulated price paths over a 30-day horizon using geometric Brownian motion with GJR-GARCH-estimated volatility and a Poisson jump-diffusion component. The result is a confidence cone showing the p5–p95 price range.

Question 3

What is the FSX Sentiment Index?

Accepted Answer

The FinStreetX Sentiment Index (FSX-SI) is a composite market mood score updated every 10 minutes. It combines AI news sentiment, a GARCH volatility penalty, probability of profit from Monte Carlo simulations, and live futures market direction (ES, NQ, YM, RTY).

Question 4

Is FinStreetX free to use?

Accepted Answer

Yes. The Free plan includes the live dashboard, sector heatmap, sentiment index, AI news agent, and preview signals. The Pro plan unlocks full Monte Carlo analysis, precise risk metrics (VaR, CVaR, Sharpe, Sortino), backtesting, and advanced SDE math tools.

Question 5

What stocks and instruments does FinStreetX cover?

Accepted Answer

FinStreetX covers 90+ instruments including major S&P 500 stocks and 28 futures contracts (ES, NQ, YM, RTY, CL, BZ, NG, GC, SI, HG, and more).

Question 6

What is GARCH volatility modeling?

Accepted Answer

GARCH (Generalized Autoregressive Conditional Heteroskedasticity) is a statistical model that estimates how volatility clusters over time. FinStreetX uses GJR-GARCH(1,1,1) — an asymmetric variant — to generate a real-time conditional volatility estimate (σ) that updates each trading session.
