What is Monopoly Money Investor?

Monopoly Money Investor is a hands-on portfolio experiment built by Chris Frost. It compares four simulated investment strategies head-to-head. You can follow portfolio growth (or decline) in one place. The approaches are AI-managed, advisor-managed, self-managed, and Junior SIPP.

The app is continuously being built and improved with help from Claude and Codex. Perplexity and Gemini are used every Friday as part of the recurring research workflow to support market review and sentiment checks before automated AI rebalance decisions are made.

Every Friday evening, the AI portfolio runs a weekly rebalance. It reviews each current holding, trims positions that no longer fit, and may replace them with better options. It records every simulated buy and sell using the latest available market price. Still simulated, still tracked seriously.

FAQ

Is this real money investing?

No. This is a simulated investment portfolio project. It is designed for strategy comparison, process testing, and performance analysis, not live execution or personal financial advice.

When does the AI rebalance run?

The automated AI rebalance cycle runs weekly, currently on Friday evening. Positions are reviewed, and simulated trade changes are recorded during that cycle.

Where does the market data come from?

Pricing is sourced from Yahoo Finance endpoints, with fallback handling when direct lookups are incomplete. Snapshot history is then stored locally for charting and comparison.
