valuation（valuation 分析）

Valuation

Utility toolkit for tracking and managing valuation-related operations. Log runs, checks, analyses, batch jobs, and reports — all with timestamped history and multi-format export.

Commands

All data commands accept optional input. Without input, they display the 20 most recent entries. With input, they log a new timestamped entry.

Core Operations

Utility Commands

Note: The export and status commands have dual roles. As core operations they log entries (when called with input). As utility commands they perform their special function (export data or show health check when called without arguments or with a format specifier).

Data Storage

All data is stored locally in ~/.local/share/valuation/:

• Per-command logs: run.log, check.log, analyze.log, batch.log, etc. — one file per command type
• History log: history.log — unified activity log with timestamps
• Export files: export.json, export.csv, export.txt — generated on demand
• Format: Each entry is stored as YYYY-MM-DD HH:MM|<input> (pipe-delimited)

Set the VALUATION_DIR environment variable to override the default data directory.

Requirements

• bash (with set -euo pipefail strict mode)
• Standard Unix tools: date, wc, du, head, tail, grep, basename, cat
• No external dependencies or API keys required

When to Use

1. Tracking valuation model runs — Log DCF runs, revenue projections, and model iterations with timestamped records
2. Recording analysis and comparison results — Use analyze and compare to document peer benchmarks, multiples, and scenario comparisons
3. Managing batch processing pipelines — Use batch and export to track large-scale valuation jobs across portfolios
4. Auditing configuration changes — Use config to log parameter changes (discount rates, growth assumptions, etc.) for reproducibility
5. Generating compliance reports — Export all logged data to JSON/CSV/TXT for audit trails, investor presentations, or regulatory filings

Examples

# Log a valuation run
valuation run "DCF model for ACME Corp — 5yr projection, WACC 9.2%"

# Record an analysis result
valuation analyze "peer comparison: ACME trades at 12x EV/EBITDA vs 15x median"

# Log a batch processing job
valuation batch "processed 50 portfolio companies for Q4 revaluation"

# Track a configuration change
valuation config "updated discount rate from 8.5% to 9.2% per board directive"

# View recent check entries
valuation check

# Search for entries related to a specific company
valuation search "ACME"

# Get summary statistics across all categories
valuation stats

# Export everything to JSON for dashboard integration
valuation export json

# Show the 20 most recent activity entries
valuation recent

How It Works

Valuation uses a simple append-only log architecture. Each command type writes to its own .log file, and all activity is also appended to a central history.log for chronological tracking. The stats command aggregates counts across all log files. The export command reads all logs and serializes them into the requested format (JSON array, CSV with headers, or plain text sections). The search command performs case-insensitive grep across all log files.
