Walsh: Multi-agent research pipeline with risk manager that can veto trades
Walsh is a multi-agent stock research system that uses specialized agents to analyze market data and a risk manager to veto trades. The system is currently in development and testing, showing a conservative bias that prioritizes risk mitigation over aggressive growth.
Why it matters
It represents the growing trend of using autonomous multi-agent systems for financial decision-making and automated risk management.
Walsh is a multi-agent stock research system that routes each ticker through four specialized agents in parallel — Fundamental, Technical, Sentiment, and Macro — aggregates their theses via a confidence-weighted Portfolio Manager, then gates the final call through a Rule-Based Risk Manager that can veto or downgrade before any trade is executed.

Backtest run: AAPL · MSFT · NVDA , Jan 2023 – Dec 2023, $100k initial capital, rule-based signal agents, strict no-lookahead enforcement.
Walsh underperformed buy-and-hold on this bull-market period. In Oct 2023, the pipeline exited all positions when momentum signals broke down and held cash for the entire month, missing a subsequent NVDA recovery rally. This is the intended behavior of the risk gate — it correctly identified a high-uncertainty period — but reveals the cost of a conservative threshold in trending markets.
