5 AI Signal Types, One Composite Score
Each signal type uses specialized machine learning models. Our ensemble combines them into a single actionable score.
Earnings NLP Signal
AI analyzes earnings call transcripts using natural language processing to detect management confidence, forward guidance tone, and hidden red flags that humans miss.
Filing Analysis Signal
Machine learning models scan SEC filings (10-K, 10-Q, 8-K) for material changes in risk factors, accounting methods, and financial metrics. Learn more in our [Master Guide to AI SEC Analysis](/blog/how-to-analyze-sec-filings-with-ai).
News Sentiment Signal
Real-time NLP sentiment analysis across thousands of financial news sources, social media, and analyst reports. Scored 1-10 on importance and sentiment direction.
Insider Activity Signal
AI distinguishes between routine 10b5-1 plan sales and genuine conviction trades by analyzing insider transaction patterns, timing, and historical context.
Composite AI Signal
Our ensemble model combines all four signal types into a single 1-10 score, weighted by historical accuracy and current market conditions for each stock.
Transparent & Auditable
Every signal comes with a confidence score, data sources used, and a link to our methodology. We publish our backtesting results and track record monthly.
Read our methodologyHow Our Machine Learning Models Work
Data Ingestion
We ingest data from SEC EDGAR (3,000+ filings/day), earnings call transcripts (4,000+ per quarter), financial news from 500+ sources, and Form 4 insider transaction filings in real-time.
NLP & Feature Extraction
Transformer-based NLP models process unstructured text to extract sentiment scores, management confidence levels, risk factor changes, and key financial metrics. We analyze both what is said and how it is said.
Signal Generation
Gradient-boosted decision trees combine extracted features with historical financial data to generate individual signal scores (1-10) for each of our 5 signal types.
Ensemble Scoring
Our meta-model weighs individual signals by their historical accuracy for each stock and sector, producing a composite AI Signal Score with a confidence interval. The weights adapt over time as the model learns.
Why Use AI Stock Signals?
Human Fatigue & Cognitive Bias
Traditional analysts often overlook subtle sentiment shifts in MD&A sections or fail to "diff" 200-page filings quarterly. Human bias often leads to "Anchoring," where prior opinions cloud new data.
The StoxPulse AI Advantage
Our LLM doesn't sleep. It treats 3,000 SEC filings with the same precision, identifying momentum convergenceacross sectors in milliseconds. By combining "Hard Data" (Revenue) with "Soft Data" (NLP Sentiment), we identify the **Alpha Gap** that institutions have used for decades.
