A buy-side analyst at a Manhattan hedge fund covers 15 companies, and every Monday she spends about two hours per stock pulling earnings, updating models and skimming sell-side notes. That’s 30 hours a week before she starts thinking.
Her firm pays for the infrastructure:
▫️ Bloomberg Terminal: about $28,000 a year
▫️ Sell-side research: $600 to $1,500 a month
▫️ Expert network calls: around $500 an hour
▫️ A junior analyst for the data work: $150K fully loaded
Roughly $250K a year per analyst, built on frameworks anyone can learn from a CFA study guide.
In May we rebuilt that workflow with Claude, and it became one of our best-performing premium pieces. Two things have changed since. GPT-6 Astra launched on September 3, and OpenAI’s own guidance says it works best with fewer instructions, so the long step-by-step prompts from that era now make it over-check and over-explain. And Instinct, Noah Shinn’s personal agent, can now take over the other half of an analyst’s week: tracking earnings dates, filings, prices and deadlines, then texting or calling you when something needs attention.
This is the rebuild for both. ChatGPT does the analysis, Instinct does the watching, and every decision stays with you.
TL;DR #
The stack: ChatGPT Plus ($20/month) runs GPT-6 Astra inside ChatGPT Work and Codex, a data connector adds about $15, and Instinct is free during its invite-only beta. About $35 a month in total.
The prompts: All 12 rewritten for Astra, each stating a goal, a deliverable and a done condition. They’re shorter than the old versions and the output is sharper.
The agent: Six standing jobs for Instinct, written as the exact texts you send it, with rules that keep it away from your brokerage account.
What’s inside the full system #
▫️ The analyst contract: one block you paste into a ChatGPT Project so all 12 prompts share the same rules on sources, verification and when to ask you
▫️ 12 copy-paste prompts rebuilt for Astra, from the first screen to position sizing and the quarterly thesis review
▫️ The Instinct layer: six standing jobs, the exact messages to send, and the boundaries for an agent that holds your logins
▫️ The operating rhythm: the weekly schedule, the 25-minute due diligence chain, the live-data setup, and the mistakes that weaken the output
