## Core Technologies & AI Algorithms

### Deep-Learning Sentiment Analysis
We scrape and process financial news feeds concurrently (yielding updates at near real-time hourly intervals), routing them through a dual sentiment pipeline:
- **FinBERT:** A specialized NLP transformer model pre-trained on financial text corpora. It reads complex articles to extract semantic polarity probability.
- **VADER:** A rule-based lexical sentiment scorer optimized for short headlines and social media streams.
Sentiment outputs are merged and mapped to a continuous scale from `0.0` (extreme panic/bearish) to `1.0` (maximum hype/bullish).

### Dynamic AI Trading Signals
The platform evaluates watchlisted stock tickers against sentiment trends and technical indicators (such as RSI and moving average crossovers) to output:
- **BUY:** High sentiment density with positive technical momentum.
- **HOLD:** Neutral price consolidation or balanced news flows.
- **SELL:** Dropping news sentiment or bearish technical divergence.

### Risk Controls & Portfolios
- **Bearish Savings:** Measures the capital saved by acting on AI warnings to exit/hedge positions prior to market pullbacks.
- **Smart Money Tracker:** Interactive calendars details unusual options sweeps, SEC Form 4 insider purchases, and Congressional STOCK Act trades.
- **AI Health Check:** Scans active holdings for sector risk concentrations and sentiment-drops.
