FOR INVESTMENT CLUBS - ONE SHARED BACKTEST
Investment clubs: argue from the same backtest
One member brings the pick, the bench runs the backtest, and the whole club debates the same chart with the same logged assumptions. Shorter meetings, better arguments.
Investment clubs that vet picks together and would rather argue about the idea than about whose spreadsheet is right.

In short
Investment club software usually means bookkeeping: unit accounting, member ledgers, tax forms. AgentTrading is the other half of the club's job, the idea vetting, and it fixes the meeting problem every club knows: four members arrive with four spreadsheets and the argument is about the data instead of the idea. Bring the pick to the bench instead. The proposing member types the thesis in plain English, "dividend blue chips, rebalanced quarterly", the rule is restated and shown before it runs, and the backtest covers 20+ years of split- and dividend-adjusted daily data with a 0.1% cost per trade assumed by default. Everyone then argues from the same chart: in our historical illustration that dividend basket HELD UP on drawdown and trailed on growth, and both halves of the verdict are printed, so the debate becomes which trade-off the club wants, which is the debate worth having. Every run logs its assumptions, so next month's meeting can reproduce this month's result. A single Analyst seat at $49 per month covers a typical club's monthly docket of ideas, well under a TrendSpider seat at $59 to $349 per month; clubs at scale can talk to sales about shared seats. One honest limitation: AgentTrading does no accounting and tracks no member capital. Educational analysis only, never advice; the club votes, and each member decides.

ON YOUR BENCH - INVESTMENT CLUBS
What changes when the vetting is honest
One backtest ends the spreadsheet war
The pick runs once, on the same 20+ years of adjusted data with the same assumptions, and the whole club reads the same chart. The argument moves from whose numbers are right to which trade-off the club wants.
Assumptions logged for the minutes
Every run records its date range, parameters, and the 0.1% default cost per trade. Paste the log into the meeting minutes and next quarter's members can reproduce this quarter's result exactly.
Verdicts a treasurer can read aloud
HELD UP, MIXED, or UNDERPERFORMED, with the risk panel in plain English underneath. No indicator fluency required to follow the discussion, so every member votes informed instead of intimidated.
One seat covers the docket
A club vetting a handful of picks per month fits comfortably in one Analyst seat at $49 per month, with PDF export for the members. Clubs at scale can talk to sales about shared seats and roles.
THE MATH - TIME, NOT MAGIC
The manual loop is 4 to 6 hours per idea
A screener, ten filings, and a spreadsheet backtest, for every single idea. The bench runs the same loop in minutes and logs what it assumed. Count what that is worth in your week.

On the same bench
A club pick runs the whole bench in one pass, described on AI stock research, and ends in the investment risk analysis panel the treasurer can read aloud. Plans start at $19 a month, cover a typical docket, and clubs that grow into a real desk should read equity research tools for teams.
QUESTIONS - ASKED AND ANSWERED
Investment clubs: the common questions
What software do investment clubs use?
Most clubs run accounting or unit-valuation software to track member contributions, a broker for execution, and some shared document for the research. The gap is nearly always the research step, where a pitch is argued from a chart and a story rather than from evidence that the rule behind it has ever worked.
How should an investment club evaluate a member's stock pitch?
Ask for the rule, not the story. Any pitch that can be written as a sentence beginning with buy when can be tested, and testing it converts an argument about conviction into a shared piece of evidence everyone can read. Agree in advance that an UNDERPERFORMED verdict settles the question, otherwise the test becomes something to argue around.
Can a whole club share one research workflow?
Yes, and the value is mostly that the process is identical for every pitch. When each idea goes through the same bench with the same 20+ years of adjusted data, the same 0.1% cost per trade and the same benchmark, the club is comparing results rather than comparing presentation skills, which is the failure mode that costs clubs money.
Does AgentTrading manage club accounting or member units?
No. It does not handle contributions, unit valuation, tax reporting, partnership accounting or execution, and it does not connect to a brokerage. It does one job: it takes an idea stated in a sentence, tests the rule behind it across history, and reports an honest verdict. Club accounting stays with whatever software you already use for it.
How do you keep a club decision from being driven by whoever argues loudest?
Put the evidence step before the discussion rather than after it. If every pitch arrives with the rule already restated, already tested and already benchmarked against buy and hold, the meeting starts from a shared document rather than from competing narratives. The point is not that the test is always right, it is that everyone is arguing about the same thing.

Who else runs the bench
Your next idea deserves a verdict, not a hunch.
Bring a thesis or a ticker. Get the evidence, the backtest, the risks, and an honest stamp. Then decide for yourself.
