Daily Stock Analysis

Deterministic daily stock analysis skill for global equities. Use when users need daily analysis, next-trading-day close prediction, prior forecast review, rolling accuracy, and reliable markdown report output.

Perform market-aware, evidence-based daily stock analysis with prediction, next-run review, rolling accuracy tracking, and a structured self-evolution mechanism that updates future assumptions from observed forecast errors.

Hard Rules

1. Read and write files only under working_directory.
2. Save new reports only to:

• <working_directory>/daily-stock-analysis/reports/

3. Use filename:

• YYYY-MM-DD-<TICKER>-analysis.md

4. If same ticker/day file exists, ask user:

• overwrite or new_version (-v2, -v3, ...)
• For unattended runs, default to new_version

5. Always review history before new prediction.
6. Limit history read count to control token usage:

• Script mode: max 5 files (default)
• Compatibility mode: max 3 files

Required Scripts (Use First)

1. Plan output path + collect history:

bash

python3 {baseDir}/scripts/report_manager.py plan \
  --workdir <working_directory> \
  --ticker <TICKER> \
  --run-date <YYYY-MM-DD> \
  --versioning auto \
  --history-limit 5

2. Compute rolling accuracy from existing reports:

bash

python3 {baseDir}/scripts/calc_accuracy.py \
  --workdir <working_directory> \
  --ticker <TICKER> \
  --windows 1,3,7,30 \
  --history-limit 60

3. Optional: migrate legacy files after explicit user confirmation:

bash

python3 {baseDir}/scripts/report_manager.py migrate \
  --workdir <working_directory> \
  --file <ABS_PATH_1> --file <ABS_PATH_2>

Compatibility Mode (No Python / Small Model)

If Python scripts are unavailable or model capability is limited, switch to minimal mode:

1. Read at most 3 recent reports for the same ticker.
2. Use only a minimal source set:

• one official disclosure source
• one reliable market data source (Yahoo Finance acceptable)

3. Output concise result only:

• recommendation
• pred_close_t1
• prior review (prev_pred_close_t1, prev_actual_close_t1, AE, APE) if available
• one improvement_action

4. Save report with same filename rules in canonical reports directory.

See references/minimal_mode.md.

Minimal Run Protocol

1. Resolve ticker/exchange/market (ask if ambiguous).
2. Run report_manager.py plan.
3. Read history_files returned by script.
4. If legacy_files exist, list all absolute paths and ask whether to migrate.
5. Gather data using references/sources.md + references/search_queries.md.
6. Run calc_accuracy.py for consistent metrics.
7. Render report using references/report_template.md.
8. Save to selected_output_file returned by report_manager.py.

Required Output Fields

Must include:

• recommendation
• pred_close_t1
• prev_pred_close_t1
• prev_actual_close_t1
• AE, APE
• rolling strict/loose accuracy fields
• improvement_actions

Self-Improvement (Required)

Each run must include 1-3 concrete improvement_actions from recent misses and use them in the next run. Do not skip this step.

Scheduling Recommendation

Recommend users set this as a weekday recurring task (for example 10:00 local time) to keep prediction-review windows continuous.
