Scenario Analyzer

Overview

This skill analyzes medium-to-long-term (18-month) investment scenarios starting from a news headline. It invokes two specialized agents in sequence (scenario-analyst and strategy-reviewer) and integrates multi-angle analysis with a critical review into a comprehensive report.

When to Use This Skill

Use this skill when:

• You want to analyze the medium-to-long-term investment impact of a news headline
• You want to construct multiple 18-month scenarios
• You want sector/stock impacts organized into 1st/2nd/3rd-order effects
• You need a comprehensive analysis that includes a second opinion

Examples:

/scenario-analyzer "Fed raises interest rates by 50bp, signals more hikes ahead"
/scenario-analyzer "China announces new tariffs on US semiconductors"
/scenario-analyzer "OPEC+ agrees to cut oil production by 2 million barrels per day"

Prerequisites

• API Keys: None (uses only WebSearch/WebFetch)
• MCP Servers: None
• Dependencies: The scenario-analyst and strategy-reviewer agents must be available via the Task tool

Workflow

Phase 1: Preparation

Step 1.1: Headline Parsing

Parse the headline provided by the user.

1. Headline check

   • Confirm a headline was passed as an argument
   • If not provided, ask the user for input

2. Keyword extraction

   • Key entities (company names, country names, institution names)
   • Numeric data (rates, prices, quantities)
   • Actions (raise, cut, announce, agree, etc.)

Step 1.2: Event Type Classification

Classify the headline into one of the following categories:

Category	Examples
Monetary Policy	FOMC, ECB, BOJ, rate hike, rate cut, QE/QT
Geopolitics	War, sanctions, tariffs, trade friction
Regulation & Policy	Environmental regulation, financial regulation, antitrust
Technology	AI, EV, renewables, semiconductors
Commodities	Crude oil, gold, copper, agricultural products
Corporate & M&A	Acquisitions, bankruptcies, earnings, industry restructuring

Step 1.3: Reference Loading

Based on the event type, load the relevant references:

Read references/headline_event_patterns.md
Read references/sector_sensitivity_matrix.md
Read references/scenario_playbooks.md

Reference contents:

• headline_event_patterns.md: Historical event patterns and market reactions
• sector_sensitivity_matrix.md: Event × sector impact-magnitude matrix
• scenario_playbooks.md: Scenario-construction templates and best practices

Phase 2: Agent Invocation

Step 2.1: Invoke scenario-analyst

Use the Agent tool to invoke the primary analysis agent.

Agent tool:
- subagent_type: "scenario-analyst"
- prompt: |
    Perform an 18-month scenario analysis for the following headline.

    ## Target Headline
    [the input headline]

    ## Event Type
    [classification result]

    ## Reference Information
    [summary of the loaded references]

    ## Analysis Requirements
    1. Use WebSearch to collect related news from the past 2 weeks
    2. Construct 3 scenarios — Base/Bull/Bear (probabilities sum to 100%)
    3. Analyze 1st/2nd/3rd-order impacts by sector
    4. Select 3-5 positive- and 3-5 negative-impact stocks (US market only)
    5. Output everything in English

Expected output:

• List of related news articles
• Details of the 3 scenarios (Base/Bull/Bear)
• Sector impact analysis (1st/2nd/3rd-order)
• Stock recommendation list

Step 2.2: Invoke strategy-reviewer

Using the scenario-analyst's results, invoke the review agent.

Agent tool:
- subagent_type: "strategy-reviewer"
- prompt: |
    Review the following scenario analysis.

    ## Target Headline
    [the input headline]

    ## Analysis Result
    [the full scenario-analyst output]

    ## Review Requirements
    Review from the following angles:
    1. Overlooked sectors/stocks
    2. Validity of the scenario probability allocation
    3. Logical consistency of the impact analysis
    4. Detection of optimism/pessimism bias
    5. Proposal of alternative scenarios
    6. Realism of the timeline

    Output constructive and specific feedback in English.

Expected output:

• Pointing out blind spots
• Opinion on the scenario probabilities
• Pointing out bias
• Proposal of alternative scenarios
• Final recommendations

---

Phase 3: Integration & Report Generation

Step 3.1: Integrate Results

Integrate the output of both agents to produce the final investment judgment.

Integration points:

1. Fill in the blind spots raised in the review
2. Adjust the probability allocation (if needed)
3. Make the final judgment accounting for bias
4. Formulate a concrete action plan

Step 3.2: Generate Report

Generate the final report in the following format and save it to a file.

Save location: reports/scenario_analysis_<topic>_YYYYMMDD.md
