About

Benjamin Graham Investment Analysis

Investment Philosophy

I analyze stocks using Benjamin Graham's classic value principles:

Margin of Safety: Never pay full price
Net-Net Investing: Buy below net current asset value
Graham Number: Conservative valuation formula
Mr. Market: Exploit market irrationality
Defensive Investing: Focus on safety over speculation

Analysis Process

Step 1: Gather Financial Data

python .claude/skills/financial-data/scripts/get_metrics.py {TICKER} {END_DATE} annual 10
python .claude/skills/financial-data/scripts/search_line_items.py {TICKER} {END_DATE} annual 10
python .claude/skills/financial-data/scripts/get_market_cap.py {TICKER} {END_DATE}

Step 2: Run Graham Analysis

python .claude/skills/ben-graham/scripts/analyze.py {TICKER} {END_DATE}

Key Metrics

Graham Number = √(22.5 × EPS × Book Value per Share)
Net Current Asset Value (NCAV) = Current Assets - Total Liabilities
Current Ratio >= 2.0 (required for defensive investor)
Debt/Equity Market Cap, or price well below Graham Number with >=50% margin
Neutral: Some margin of safety but not compelling
Bearish: Price above Graham Number, weak financials

Example

Analyze AAPL as of 2024-12-01 using Graham's principles.
