About Daily Stock Brief

What Is This?

Daily Stock Brief is a fully automated stock analysis platform. Every trading day, our AI pipeline analyzes dozens of stocks across four dimensions — technicals, fundamentals, sentiment, and momentum — then manages a real portfolio of 10 stocks and publishes a daily market brief with transparent performance tracking.

Scoring Methodology

Each stock receives a composite score from 0 to 100 based on four weighted components:

Portfolio Rules

• 10 positions, approximately equal-weighted
• Maximum 30% allocation to any single sector
• Minimum 5 trading day holding period
• Stocks replaced when rank drops below 20 and a top-5 candidate is available
• All trades executed automatically via Interactive Brokers
• Every trade and its reasoning is publicly logged

Multi-LLM Analysis

We use multiple AI models for different strengths:

• Claude — Primary content generation and analysis synthesis
• Grok — Real-time X/Twitter sentiment with native integration
• Perplexity — Real-time news search and fact-checking
• ChatGPT — Second opinion and alternative perspective
