# ๐ Volatility Forecasting in South Africa Stock Market
## ๐ง Project Overview
This project builds a **volatility forecasting system** for the South African stock market using financial time series modeling and a production-ready backend architecture.
It combines:
- ๐ Financial modeling (GARCH)
- ๐๏ธ Database integration (SQLite)
- ๐ API development (FastAPI)
- ๐ก External data ingestion (Alpha Vantage)
The goal is to simulate how real-world financial systems **forecast risk and serve predictions via an API**.

## ๐ฏ Key Features
- ๐ฅ Fetches stock market data using Alpha Vantage API
- ๐งฎ Computes returns and volatility
- ๐ Implements **GARCH models** for volatility forecasting
- ๐๏ธ Stores data using a **SQLite database**
- ๐งฑ Uses a **Repository Pattern (SQLRepository)** for clean architecture
- โก Exposes predictions via a **FastAPI backend**

## ๐งฉ Methodology
### 1. Data Ingestion
- Stock data is fetched from Alpha Vantage API
- Data is cleaned and stored in SQLite
### 2. Data Processing
- Log returns are computed
- Time series prepared for modeling
### 3. Volatility Modeling
- GARCH models are used to capture:
- Volatility clustering
- Time-varying risk
### 4. Backend System
- FastAPI serves predictions through endpoints
- Repository pattern ensures modular database access
