AI for Investment Fund Manager
A portfolio manager at a small firm spends an estimated 8 hours a week on investor letters, quarterly commentary, follow-ups and the number checks behind them, and about 3.5 more on DDQs and strategy decks. Add roughly 3 hours of review rounds with the CCO and another 3 hours of holdings and thesis monitoring, and the writing and checking crowd out the research. The guides below put AI to work around the investment work: first drafts from your own notes and figures, reading notes tied to page numbers, checks of a draft against your figures table, and weekly digests that tell you what is due. The investment decisions, the figures and the CCO's approval stay where they are.

A rewritten version of your request that asks for what an experienced professional would ask for.
Here's a task I'm about to do: [describe the task]. Don't do it yet. First, tell me how the best person in my field would approach it: what they would check that I haven't mentioned, what raw information they would want instead of a summary, and how they would prove the result is right. Then rewrite my request so it asks for that version.
View full prompt →Tip: - Check the result against something outside the chat: the official source, last period's actual figures, a colleague who knows the area, or a calculator. The AI saying its answer is right proves nothing.
A one-page thesis note for a holding, laid out under five fixed headings, built only from the notes you paste and with gaps left visible.
Turn my rough notes into a one-page thesis note under these headings: What the company does, Why I hold it, What I am watching, What would change my mind, Next review date. Use only my notes. Add no view and no figure. Write [not in notes] under any heading the notes do not cover. Notes: [paste your notes]
View full prompt →Tip: Read the note against your original notes and delete any phrase that is not yours. The tool should add nothing, and if it does, rerun with the sentence "Do not paraphrase beyond tidying grammar."
Two lists drawn only from the excerpts you paste: statements that support your belief and statements that cut against it, each with its page, plus what the documents do not say.
Here is my belief: [belief]. Using only the excerpts below, list statements that support it and statements that cut against it, each with its report and page. Then list what the excerpts do not say that I would need to judge it. No verdict. Excerpts: [paste excerpts with report and page markers]
View full prompt →Tip: Paste the same kind of passage from each year, such as the plan and the result, so the comparison is fair. Count the items on each side yourself, because the tool can miss a line.
A pre-mortem on one of your theses: reasons it could have failed a year from now, grouped under five headings, each with a question you can check in a filing or on a call.
Assume my thesis failed a year from now. List the reasons it could have failed, grouped as Business, People, Balance sheet, Market, Information gaps. Under each reason write one question that can be checked in a filing or on a call. Questions only. No answers and no view on how likely any reason is. Thesis: [paste thesis]
View full prompt →Tip: Delete any reason that sounds generic and keep the ones that make you uncomfortable. If the tool slips into answers or probabilities, reply "Questions only" and rerun.
A list of questions for a management meeting or earnings call, grouped by thesis point, each tied to the line of the public release it tests.
Write questions for management, grouped by my thesis points. Beside each question quote the release line it tests. Ask only about what the company has disclosed or could disclose to everyone. No answers and no view. Thesis points: [paste points] Public release: [paste text]
View full prompt →Tip: Delete any question that probes for something the company would not tell every investor alike. If the tool drafts one, tell it to rewrite the question around the public line.
A list of questions an investor or advisor audience may ask, with the place in your approved materials where each answer sits and a flag where none does.
List questions an [audience, e.g. advisor] audience may ask about this strategy. Beside each, name the section of the approved text below that answers it. If none does, write [no approved answer: ask the CCO]. Do not write any new answer. Approved text: [paste approved materials]
View full prompt →Tip: Answer from the approved text and copy any figure from the firm's records on the day. A question about past results is one for your CCO's approved language, never for the tool.
An agenda with a time slot per item and the decision for each item written as a question for the committee.
Build an investment committee agenda. Total time: [minutes]. Items and the decision the committee must make on each: [list]. Give each item a time slot so the slots add up to the total. Write each decision as a question for the committee. Do not suggest what the committee should decide.
View full prompt →Tip: Add the slots yourself before you send the agenda. If the tool puts a recommendation under any item, delete it.
Groups of due diligence questions that ask the same thing, one proposed library entry name per group, and a list of questions that fit no group.
Group these due diligence question headings by what they ask. Give each group a library code (LIB-01, LIB-02...) and a short name. List questions that fit no group separately. Headings only. Write no answers. Questions: [paste headings]
View full prompt →Tip: Paste headings only, with no answers and no consultant or investor names. Read each group and move any question that does not belong.
A short Python script that flags duplicate holding codes, blank or unreadable dates and weights outside 0 to 100, printing the row number for each flag.
Write a Python 3 script, standard library only (csv, datetime), for a CSV with columns Holding code, Sector code, Weight, Last review date. Flag duplicate holding codes, blank or unreadable dates (YYYY-MM-DD) and weights below 0 or above 100. Print the file row number and reason for each flag. Take the file path as an argument. No other output.
View full prompt →Tip: Ask your IT contact before you run code from any source, and read each line first. The flags tell you where to look, and your portfolio system stays the record.
A one-page briefing note for a consultant meeting under fixed headings, with a bracketed placeholder wherever a figure belongs.
Write a one-page briefing note under: Strategy in brief, Team, Process, Recent changes, Open questions from the consultant. Use only the approved text below. Put a bracketed placeholder for every figure, such as [AUM as of quarter end from the firm's records]. Add no claim. Approved text: [paste]
View full prompt →Tip: Search the finished note for any number you did not paste yourself and delete it. A phrase that compares the strategy with others or looks ahead goes to your CCO for review.
A minutes draft under fixed headings in which every unclear point is marked "[confirm]" instead of smoothed over.
Draft committee minutes from my notes under: Attendees (by role), Items, Decisions exactly as recorded, Actions with owner, Open items. Add no reason, vote or decision that is not in my notes. Mark every unclear point [confirm]. Notes: [paste notes]
View full prompt →Tip: Read the Decisions section against your notes line by line. If a reason appears there that you did not write, delete it.
Reading notes on a public document excerpt under five fixed headings, with a page reference after every line so you can trace each note to its source.
Write reading notes on the excerpt below under these headings: Business, Results as stated, Risks as stated, Management statements, Items not discussed. Put the page in brackets after every line. Add no view and no figure that is not in the excerpt. Write "not stated" where the excerpt is silent. Excerpt: [paste text with page markers]
View full prompt →Tip: Keep the page markers in the pasted text, because the tool can only cite pages it can see. If a note carries a number, compare it digit by digit with the page before you copy it anywhere.
A checklist of questions with answer space that you use on every analyst pitch, written from your own description of what a good pitch contains.
From my notes on what a good pitch contains, build a checklist of questions with a blank answer line under each. Keep my wording and order. Do not add criteria that are not in my notes. Do not score or rate any security. Put a compliance question on where the information came from. My notes: [paste notes]
View full prompt →Tip: Keep sizing as a question for you to decide, never an item the tool answers. Use the checklist as a reading guide on each pitch. You and the committee judge the pitch itself.
Three case questions built on invented companies, a scoring guide you can edit, and a four-week reading plan listed by topic.
Our analyst role: [role and skills]. Write three interview case questions on invented companies only. Add a scoring guide I can edit, and a four-week reading plan by topic, not by title. I will choose the documents. No real company names.
View full prompt →Tip: Run the cases through a colleague first to check they have a sensible answer. Hiring decisions and interview rules stay with you and your firm's HR process.
A short feedback note for an analyst under three headings, in your own tone, built only from what your notes say.
Turn my notes after an analyst pitch into a short note under three headings: What worked, What to tighten, Questions to answer by the next meeting. Keep my tone and plain wording. Add nothing my notes do not say. Notes: [paste notes]
View full prompt →Tip: Send the note only after you have changed any line that says more than you meant. Feedback on a person's work is a record, so follow your firm's policy on where it is kept.
