Resolution overview

The multi-agent funding analysis assistant consists of a supervisor agent and three subagents (quantitative evaluation agent, information agent, and good summarizer agent) working collectively in a coordinated framework, as proven within the following diagram.

The supervisor agent makes use of the directions you present to know the construction and position of every collaborator agent. The supervisor agent orchestrates the general funding analysis course of by breaking down consumer prompts, delegating subtasks to specialised subagents, and consolidating their outputs to generate the ultimate response. Every subagent is configured to hold out specialised duties as follows:

• Quantitative evaluation agent
  • Capabilities – Powered by stock-query and portfolio-optimization motion teams.
  • Tasks – Question and analyze historic inventory knowledge and construct optimized portfolio allocations based mostly on consumer inputs similar to inventory tickers or funding quantity.
• Information agent
  • Capabilities – Powered by the web_search motion group and the financial_analysis_KB data base.
  • Tasks – Search and retrieve related monetary knowledge similar to earnings experiences and filings from the data base for context. If data isn’t current within the data base, assemble an online question. Handles queries associated to analyzing firm financials, efficiency drivers, and administration commentary.
• Good summarizer agent
  • Capabilities – Makes use of LLM capabilities with particular immediate directions, no customized motion group.
  • Tasks – Takes in output from different subagents, similar to current information and monetary knowledge, and synthesizes the knowledge into structured funding insights. Summarizes lengthy texts or paperwork similar to earnings experiences into concise insights.

Multi-agent collaboration works as follows:

1. Consumer prompts the multi-agent funding analysis assistant with a high-level analysis question.
2. Supervisor agent breaks the question into subtasks and orchestrates and invokes the related subagents in parallel or sequentially as wanted:
   • Information agent to retrieve monetary experiences or knowledge
   • Quantitative evaluation agent for inventory knowledge evaluation
   • Good summarizer agent to summarize prolonged texts
3. Supervisor agent consolidates the subagent outputs together with the unique question context.
4. Supervisor agent passes the consolidated data to the LLM to generate the ultimate analysis insights.

This structure makes use of the strengths of the totally different specialised brokers to comprehensively deal with the assorted features of funding analysis, and the supervisor agent gives the clever orchestration.
