The Client Communication Generator


Step 1: The Brain Dump (2 minutes)


Open your LLM and dump everything you know. Do not organize it. Do not worry about structure. Just get it out:


You are a senior investment writer at a long-only equity fund. I am going to dump my raw notes on a position. Your job is to turn this into polished client communication.

Here are my raw notes on [TICKER]:

[PASTE EVERYTHING: bullet points, sentence fragments, numbers, your gut feeling, concerns, why you like it, what could go wrong — everything, unstructured, messy]

My investment thesis in one sentence: [YOUR ONE-SENTENCE THESIS]
My conviction level: [HIGH/MEDIUM/LOW]
Position sizing: [CURRENT WEIGHT AND WHETHER YOU ARE ADDING/HOLDING/TRIMMING]
Time horizon: [3 months / 6 months / 1 year+]

Step 2: Draft the Memo (2 minutes)


Now write a client-facing investment memo with this structure:

HEADER:
- Company name, ticker, current price, market cap
- Recommendation: [BUY/HOLD/SELL] | Price Target: [X]
- One-sentence thesis

INVESTMENT THESIS (2 paragraphs):
- Why we own this. What is the opportunity? What is the market missing?
- Be specific: cite numbers, margins, growth rates, catalysts. No vague language.

RISK FACTORS (1 paragraph):
- What could go wrong. Be honest — clients respect candor.
- For each risk, briefly note the mitigation or monitoring trigger.

CATALYST TIMELINE:
- Bulleted list of upcoming catalysts with dates
- Expected impact of each (positive, negative, or clarifying)

POSITION DETAIL:
- Current weight, entry price, performance since entry
- What would make us add? What would make us exit?

FORMATTING RULES:
- Professional but not corporate. Write like you are talking to a smart LP.
- No jargon that requires a finance degree. Explain complex ideas simply.
- Use numbers, not adjectives. "Revenue grew 23% YoY" not "revenue grew significantly."
- Total length: 400-600 words. One page maximum when formatted.

Step 3: The Quality Check (1 minute)


Review the memo you just wrote against these criteria:

1. CLAIM CHECK: Every factual claim in the memo — is it supported by the raw notes I provided? Flag anything that is inferred vs stated.
2. TONE CHECK: Read this as a client who is trusting us with their money. Does it feel confident without being reckless? Honest without being defensive?
3. CONSISTENCY CHECK: Does the thesis logically lead to the recommendation and position sizing? If the thesis is "strong growth story" but the sizing is 1%, that is inconsistent.
4. QUESTION ANTICIPATION: What is the first question a skeptical client would ask after reading this? Add a one-sentence answer at the end.
5. PRECISION: Replace any remaining vague language with specific numbers or remove it entirely. "Significant growth" should become "23% revenue growth" or be deleted.

Give me the revised version.



Adapting for Different Audiences


The same investment thesis needs different memos for different audiences. After the first draft, you can quickly generate variants:


Rewrite this memo for:
A) A quarterly letter to institutional LPs (more formal, longer, focus on process and risk management)
B) An internal CIO briefing (shorter, assume high financial literacy, skip context, focus on the trade)
C) A retail client newsletter (simpler language, more context, focus on the "so what")

Three audiences, three memos, 60 seconds each. That is what used to take an afternoon.




The Template Library


After running this workflow 5-10 times, you will have a library of memo templates. Save your best outputs and reference them:


Write this memo in the style of [PASTE YOUR BEST PRIOR MEMO]. Match the tone, structure, and level of detail.

This compounds over time. Your first memo takes 5 minutes. Your 50th memo takes 3 minutes because the AI has learned your voice from examples.




A Note on Compliance


If you work at a regulated firm, every client communication may need compliance review. This workflow produces the first draft — it does not replace your compliance process. But moving from "blank page to reviewed draft" in 5 minutes instead of 45 means your compliance team gets the memo sooner and you spend more time on analysis.
