What it does
Ben Graham is an agent skill from monarchjuno/vibe-investing. Analyze an investment through Benjamin Graham's conservative value-investing lens.

When your agent uses it
- The analysis should focus on margin of safety
- Balance-sheet strength
- Earnings stability
- Graham-style valuation measures such as Graham Number
Example prompts

Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 15954a6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ben Graham loads about 689 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 316 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Ben Graham
Overview
Use this skill to evaluate whether a security offers true margin of safety based on hard assets, conservative earnings power, and financial strength.
Core Principles
- Demand a margin of safety before becoming interested.
- Favor balance-sheet strength over exciting stories.
- Prefer proven earnings stability to optimistic future growth.
- Treat dividends and conservative capital structure as signs of discipline.
- Avoid speculative businesses, promotional narratives, and fragile financing.
Required Analysis Sequence
1. Check financial strength
- Review leverage, liquidity, working-capital coverage, and near-term solvency.
- Favor companies with ample current assets and manageable obligations.
2. Review earning power
- Examine whether earnings have been stable across multiple years.
- Penalize cyclicality, sharp earnings volatility, or repeated losses.
3. Apply conservative valuation
- Use Graham-style valuation anchors such as earnings-based valuation, asset backing, net current asset value, or similar downside-aware measures.
- Avoid relying on distant terminal optimism.
4. Judge the margin of safety
- Compare current price with conservative value estimates.
- State whether the discount is large enough to protect against error.
5. Frame the decision
- End with a clear stance and explain whether the case is supported by asset protection, earnings stability, and valuation discount.
Decision Rules
- Lean bullish when the company is financially strong, reasonably understandable, and available at a clear discount to conservative value.
- Lean bearish when price leaves no margin of safety, leverage is high, or the business requires speculation about future growth.
- Stay neutral when valuation is near fair conservative value or when the balance sheet and earnings quality send mixed signals.
Risk and Uncertainty Rules
- State when asset values are questionable, earnings are cyclical, or accounting quality is uncertain.
- Lower confidence when a thesis depends on adjustments that Graham would have treated skeptically.
Anti-Hallucination Rules
- Do not invent balance-sheet strength, dividend history, or intrinsic value.
- Distinguish reported figures from normalization assumptions.
- If liquidation value or NCAV cannot be estimated reliably, say so instead of forcing the framework.
