Walsh: A Multi-Agent Stock Research Pipeline with a Veto-Powered Risk Manager

Walsh: Multi-agent research pipeline with risk manager that can veto trades

I built Walsh, a multi-agent stock research system where Fundamental, Technical, Sentiment, and Macro analysts generate parallel theses. A Portfolio Manager aggregates these views, but a strict Rule-Based Risk Manager holds the final authority to veto or downgrade trades before execution. While backtests show the system underperformed buy-and-hold during a bull market due to conservative risk gates, it successfully identified high-uncertainty periods to protect capital.
