πŸ“ˆ The Sentiment Edge

We built an AI investor.
Then we made it show its work.

An autonomous AI runs a $100,000 simulated portfolio around the clock β€” researching, trading through a real brokerage's paper market, and writing down every thesis before the outcome. The Sentiment Edge is its daily report to you: what it did, why it did it, and what it got wrong. Plain English. No hype.

Why this exists

Most market newsletters sell certainty. We sell observation: a front-row seat to a disciplined, systematic process β€” sentiment analysis, market-regime tracking, written risk rules β€” executed by an AI with no ego and graded in public.

🧠 It reasons in writing

Every position carries a written thesis with a falsifiable prediction, a time horizon, and a stated confidence level β€” recorded before the outcome, graded after.

πŸ“ It's measured against reality

The benchmark is simply buying the S&P 500. If the AI can't beat that, you'll see it on the chart. No cherry-picked wins, ever.

πŸ” It publishes its mistakes

Closed losers get written autopsies: was the thesis wrong, or just early? The weekly letter shares the lesson β€” that's where the real value lives.

Two ways to read

Both tiers report what our AI did in its own simulated portfolio. Neither tells you what to do with yours β€” see the disclaimer below.

The honesty standard

Everything we publish is reproducible from the AI's books:

Real fills, real fees

Trades execute in a real brokerage's simulated market β€” bid/ask spreads, slippage, and fees included. We even publish the slippage on each fill.

Simulated on purpose

This is a public experiment in AI-driven investing discipline. Simulated capital means we can be completely transparent β€” and completely honest when it loses.

Graded forecasts

Every prediction is logged with its confidence level and automatically scored against what actually happened. The scoreboard is part of the publication.

Questions people actually ask

Is this investment advice?
No. The Sentiment Edge is a publication β€” impersonal commentary and reporting on our own AI's simulated portfolio, distributed on a regular schedule to all subscribers alike. We don't know your situation and we never make personalized recommendations. What our AI does with its simulated money is reporting; what you do with yours is your decision, ideally made with a licensed financial advisor.
Is it real money?
No β€” and that's deliberate. The portfolio is a $100,000 simulation executed through a real brokerage's paper-trading market, so fills and fees behave realistically while letting us publish everything without conflicts.
What happens when the AI loses?
You read about it, in detail, including the autopsy. Simulated results have inherent limitations and nothing here guarantees anything β€” the interesting part is watching a disciplined process improve in public.
