@CompaCompu Thanks ! Everything is well on my side.
Hope same for you.

This is exactly why people say AI fails at investing..
Generic prompts + no context + no investing expertise = generic unreliable answers.

I started this newsletter 6 months ago:

•18,000 subscribers

•Substack Bestseller badge

From day one, I made a simple decision.

I would share everything in my notes and in the weekly newsletter:

•Frameworks and processes that actually work in practice.

•Prompts I validate only after testing them on at least 15 stocks.

I deeply believe that AI makes investing research 10× faster and deeper.

You only need the right frameworks.

That is what this newsletter is about.

@MikeFritzell @firstadopter I’ve been a user and promoter of Gemini for investing and professional research.
But for my personal life, l can’t replace ChatGPT

Most of the masses usage is personal, and having the most powerful reasoning model or advanced calculations isn’t the most important thing to me

Paste this into Gemini Deep Research.

It’ll help you understand the basics of any stock in minutes.

You are an equity analyst writing a high-quality company brief for long-term investors.

Analyze [Ticker] using the 7-point framework below.

Use only verifiable, factual information (annual reports, investor presentations, filings, earnings transcripts, and reputable financial sources).

Be concise, analytical, and concrete — no filler or marketing language.

Output format (exact structure required):

Executive Summary (≈150–200 words)

Summarize in plain English how this company makes money, its economic quality, and where its edge and risks lie.

End with one sentence stating how you’d describe the business to an investor in one line.
1. What They Sell and Who Buys

Describe the main products or services.

Define target customers (type, segment, geography) and why they buy — main pain point or motivation.

2. How They Make Money

Explain the revenue model and pricing logic.

Clarify whether it’s one-time, recurring, transaction-based, or hybrid.

Include key revenue segments and their share if available.
3. Revenue Quality

Assess how predictable and diversified revenues are.

Break down recurring vs one-off components, customer or segment concentration, and exposure to cycles.

4. Cost Structure

Outline major cost drivers (COGS, labor, logistics, marketing, etc.).

Include gross and operating margins where possible.

Comment on scalability — fixed vs variable costs and how margins move with growth.

5. Capital Intensity

Describe assets needed to run and grow operations.

Include capital expenditures, working-capital needs, and cash conversion efficiency.

6. Growth Drivers

Identify the main levers for revenue growth — volume, pricing, product mix, geographic expansion, or acquisitions.

Clarify if these are structural (long-term) or cyclical (short-term).

7. Competitive Edge

Explain what protects the company’s economics from competition: brand, cost advantage, switching cost, regulation, network effects, data, or IP.

Mention how durable and testable this moat appears based on financial evidence (margins, ROIC, retention).

Tone: Analytical, neutral, precise.

Goal: Produce a concise yet rich narrative that lets an investor understand how this business actually works.
