The 60-Minute Filter for Equity Research using Gemini
How I use Gemini DeepSearch to decide if a company deserves my time, in under 60 minutes.
One of the most under-discussed problems in investing is not valuation.
It’s time allocation.
Most investors don’t lose money because they lack information. They lose money because they spend weeks researching businesses that were never worth that effort in the first place.
Over time, I realised something uncomfortable.
Deep research is not the starting point.
Filtering is.
This article explains the 60-minute AI-assisted workflow I now use to decide whether a company deserves deeper research at all. Not whether it’s a “good” or “bad” company. Just whether it has earned more of my time.
The Real Objective: Time, Not Certainty
This process is not designed to produce conviction.
It’s designed to answer a much simpler question:
Is this business clear, durable, and understandable enough to justify deeper work right now?
That distinction matters.
A company can be excellent and still fail this filter.
That doesn’t make it a bad business.
It just means the signal is too weak, too noisy, or too complex at this stage.
Time is capital. This workflow is about allocating it rationally.
Why AI Fits This Stage Perfectly
AI is often misused in investing.
People try to outsource judgment to it.
That’s backwards.
Where AI actually shines is compression:
compressing documents,
compressing years of disclosures,
compressing complexity into first-order signals.
In this workflow, AI does not decide anything.
It simply speeds up the part that humans are worst at doing efficiently.
Judgment stays human.
Step 1: AI Deep Business Review
The first step is an AI-driven deep business review.
The goal here is not summarisation.
It’s to understand the economic engine of the business.
At this stage, I want clarity on:
what the company actually sells,
where revenue and profits truly come from,
how margins differ across segments,
how capital-intensive the business is,
whether returns are driven by structure or circumstance,
and what the real risks look like beneath the surface.
I treat this like an acquisition-style review, not a stock pitch.
This step alone eliminates a surprising number of companies.
If the economics are weak, fragile, or overly dependent on narratives, I stop.
No models. No valuation. No sunk-cost fallacy.
→ First, use Gemini with DeepSearch to generate an expert-level business analysis.
Prompt for deep research:
You are a senior equity research analyst and portfolio manager with experience evaluating businesses for long-term capital allocation.
Your task is to analyze [COMPANY NAME] as if you were deciding whether to deploy meaningful capital into the business, or acquire it outright.
The objective is not to summarize the company.
The objective is to understand how the business actually makes money, how durable that engine is, and whether it deserves deeper research time.
TIME PERIOD (MANDATORY):
Use data strictly from FY2021 to FY2025.
If FY2025 is not fully available, use the latest available FY results and explicitly state the cutoff.
Base your analysis ONLY on high-signal sources:
- Official company filings and annual reports (FY2021–FY2025)
- Investor presentations (FY2021–FY2025)
- Earnings call transcripts (FY2021–FY2025)
- Peer disclosures for comparison
- Credible industry and market research
- Expert commentary where relevant
Avoid promotional language.
Avoid repeating management narratives.
Write as if this analysis will be reviewed in an internal investment committee.
Structure your analysis as follows:
1. Business Reality Check (FY2021–FY2025)
- What does the company actually sell, and to whom?
- Revenue breakdown by product, geography, and channel (FY2021–FY2025)
- Where is real economic value created?
- Branded vs non-branded mix (if applicable)
- Customer concentration and buying behavior
- Seasonality and cyclicality
- Segment-level margin structure
- Has the business generated sufficient internal cash to fund growth during FY2021–FY2025?
2. Market Position and Competitive Edge
- Realistic addressable market the company can capture today
- Structural tailwinds and headwinds visible in FY2021–FY2025
- Direct and indirect competitors
- Sources of competitive advantage (pricing, brand, scale, distribution, cost)
- Evidence of pricing power in the last 5 years
- Durability of advantages over the next 5–10 years
- External risks that could structurally impair the business
3. Financial Engine Quality (FY2021–FY2025)
- Revenue, EBIT, and free cash flow trends (FY2021–FY2025)
- Margin stability and volatility across the period
- ROIC relative to cost of capital
- Capital reinvestment efficiency
- Capex and working capital intensity
- Balance sheet strength and dilution history
- Predictability and quality of free cash flows
4. Growth Reality Test
- What actually drove growth from FY2021 to FY2025?
- What management claims will drive growth next?
- Which growth levers are realistically executable?
- Rank growth levers by impact on profitability and returns
- What would need to go right to materially grow earnings over the next 3–5 years?
5. Management and Capital Allocation Discipline
- Key decision-makers and leadership structure
- Ownership and incentive alignment
- Execution track record over FY2021–FY2025
- Capital allocation behavior (capex, M&A, dividends, buybacks)
- Consistency of strategy over time
6. Risk, Fragility, and Hidden Optionality
- Top structural risks evident today
- Downside scenarios and failure modes
- Risk mitigants
- Underappreciated assets or strategic levers
Final output must include:
- A concise executive summary written for an investment committee
- A clearly labeled FY2021–FY2025 financial snapshot
- Segment- and geography-level economics
- Moat durability assessment
- Ranked growth levers
- Capital allocation scorecard
- Risk map with commentary
Do not speculate.
If data for any FY year is unavailable, explicitly state so.
All judgments must be grounded in evidence.A free Gemini account is sufficient.
Step 2: One-Page Business Compression
If the business survives the first step, I compress everything into a single-page visual summary.
→ I compress the entire analysis into a one-page infographic.
This forces clarity on revenue pools, profit drivers, capex needs, working capital pressure, and where value is really created.
This is a forcing function.
A one-page view makes it very hard to hide:
poor ROIC,
messy segment economics,
bloated capex,
or unclear value drivers.
It also reveals something important very quickly.
Whether the business has a coherent shape.
In my experience, genuinely strong businesses tend to become clearer when compressed.
Weak or overly complex businesses become more confusing.
If I cannot understand the company on one page, I pause.
Not because the company is bad.
But because it hasn’t earned deeper time yet.
Step 3: Understanding Check
The final step is the most misunderstood.
→ Third, I test my understanding using a quiz generated from the same analysis.
Not factual questions. Business mechanics.
By asking questions like:
Why do margins differ across segments?
Which segment actually drives returns?
What breaks first in a downturn?
This is not an intelligence test.
It’s a clarity test.
If, even after the deep review and one-page compression, the answers still don’t click, one of two things is true:
the business model is genuinely complex and requires much deeper work, or
the signal-to-noise ratio is too low for a quick filter.
In both cases, I don’t proceed further at this stage.
That’s not rejection.
That’s discipline.
What This Workflow Is (and Is Not)
This process is:
a time-allocation filter,
a bias-reduction tool,
a way to avoid falling in love with “interesting” companies.
It is not:
a replacement for full research,
a valuation framework,
or a shortcut to conviction.
It simply ensures that when I do go deep, I’m doing so on businesses that have already demonstrated clarity, durability, and economic logic.
The Edge Is the Combination
AI compresses weeks of analyst work into under an hour.
Human judgment decides whether the idea survives.
Used this way, AI doesn’t make investing easier.
It makes it cleaner.
And in markets, cleanliness of thinking is often more valuable than speed.
