Headline Scenario Analyzer

Overview

This skill analyzes medium-to-long-term (18-month) investment scenarios starting from news headlines. It sequentially calls two specialized agents (

scenario-analyst

and

strategy-reviewer

) to generate a comprehensive report that integrates multi-faceted analysis and critical reviews.

When to Use This Skill

Use this skill in the following cases:

Want to analyze medium-to-long-term investment impacts from news headlines
Want to build multiple scenarios for 18 months later
Want to organize impacts on sectors and stocks into primary/secondary/tertiary levels
Need comprehensive analysis including a second opinion
Need report output in Japanese

Examples of use:

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

Workflow

Phase 1: Preparation

Step 1.1: Headline Analysis

Analyzes the headline input by the user.

Headline Verification
- Verify if a headline is passed as an argument
- If not, prompt the user for input
Keyword Extraction
- Key entities (company names, country names, institution names)
- Numeric data (interest rates, prices, quantities)
- Actions (hike, cut, announce, agree, etc.)

Step 1.2: Event Type Classification

Classify the headline into the following categories:

Category	Examples
Monetary Policy	FOMC, ECB, BOJ, rate hike, rate cut, QE/QT
Geopolitics	War, sanctions, tariffs, trade frictions
Regulation & Policy	Environmental regulation, financial regulation, antitrust law
Technology	AI, EV, renewable energy, semiconductors
Commodities	Crude oil, gold, copper, agricultural products
Corporate & M&A	Acquisition, bankruptcy, earnings results, industry restructuring

Step 1.3: Reference Loading

Load relevant references based on the event type:

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

Reference Contents:

```
headline_event_patterns.md
```
: Past event patterns and market reactions
```
sector_sensitivity_matrix.md
```
: Event × sector impact matrix
```
scenario_playbooks.md
```
: Scenario building templates and best practices

Phase 2: Agent Invocation

Step 2.1: Call scenario-analyst

Call the main analysis agent using the Task tool.

Task tool:
- subagent_type: "scenario-analyst"
- prompt: |
    Please perform an 18-month scenario analysis for the following headline.

    ## Target Headline
    [Input Headline]

    ## Event Type
    [Classification Result]

    ## Reference Information
    [Summary of loaded references]

    ## Analysis Requirements
    1. Collect relevant news from the past 2 weeks using WebSearch
    2. Build 3 scenarios: Base/Bull/Bear (total probability 100%)
    3. Analyze primary/secondary/tertiary impacts by sector
    4. Select 3-5 stocks with positive/negative impacts (US market only)
    5. Output all content in Japanese

Expected Output:

List of relevant news articles
Details of 3 scenarios (Base/Bull/Bear)
Sector impact analysis (primary/secondary/tertiary)
Recommended stock list

Step 2.2: Call strategy-reviewer

Call the review agent based on the analysis results from scenario-analyst.

Task tool:
- subagent_type: "strategy-reviewer"
- prompt: |
    Please review the following scenario analysis.

    ## Target Headline
    [Input Headline]

    ## Analysis Results
    [Full output from scenario-analyst]

    ## Review Requirements
    Conduct a review from the following perspectives:
    1. Overlooked sectors/stocks
    2. Appropriateness of scenario probability allocation
    3. Logical consistency of impact analysis
    4. Detection of optimistic/pessimistic bias
    5. Proposal of alternative scenarios
    6. Realism of timeline

    Please provide constructive and specific feedback in Japanese.

Expected Output:

Points of oversight
Opinions on scenario probabilities
Points of bias detection
Proposals for alternative scenarios
Final recommendations

Phase 3: Integration & Report Generation

Step 3.1: Result Integration

Integrate the outputs from both agents to create the final investment decision.

Integration Points:

Complement omissions pointed out in the review
Adjust probability allocation (if necessary)
Final judgment considering bias
Formulate specific action plans

Step 3.2: Report Generation

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

Save Path:

reports/scenario_analysis_<topic>_YYYYMMDD.md
