What it does
Undervalued Stock Screener is an agent skill from Geeksfino/finskills. Screen and identify undervalued stocks with strong fundamentals using professional equity research methodology. Use when the user asks to find undervalued stocks, screen for cheap or bargain stocks, identify value investing opportunities, perform fundamental stock analysis, find stocks trading below intrinsic value, or requests a stock screener based on financial metrics like P/E ratio, debt-to-equity, free cash flow, or ROIC.
Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/output-template.md` and `references/screening-methodology.md`).
It sits in Business, Finance & HR, covering Stock and market analysis. The repository describes itself as: Financial engineering and risk/compliance skills for agents. The licence is Apache-2.0.
When your agent uses it
- The user asks to find undervalued stocks
- Screen for cheap
- Identify value investing opportunities
- Perform fundamental stock analysis
Example prompts
- “/undervalued-stock-screener”
Workflow steps
4 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 8722415. 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
Undervalued Stock Screener loads about 968 tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 420 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.

Undervalued Stock Screener
Act as a professional equity research analyst. Scan the current stock market to identify undervalued companies with strong fundamentals using a structured, multi-filter screening methodology.
Workflow
Step 1: Confirm Screening Parameters
Before screening, confirm with the user:
- Number of stocks to identify (default: 10)
- Market scope — US only, global, or specific regions/exchanges
- Sector preferences — any sectors to include or exclude
- Market cap range — large-cap, mid-cap, small-cap, or all
- Additional filters — any custom criteria beyond the defaults
If the user wants defaults, proceed with the standard filters below.
Step 2: Apply Screening Filters
Apply ALL of the following quantitative filters. See references/screening-methodology.md for detailed criteria, thresholds, and edge cases.
| Filter | Criterion |
|---|---|
| Valuation | P/E ratio below industry average |
| Growth | Consistent revenue and earnings growth over 3–5 years |
| Leverage | Debt-to-equity ratio below sector median |
| Cash Flow | Positive and growing free cash flow |
| Returns | ROIC above industry average |
| Upside | Analyst consensus upside ≥ 30% |
Step 3: Deep-Dive Analysis
For each qualifying company, perform a deep-dive analysis covering:
- Business Overview — What the company does, its market position, competitive moat
- Why It Appears Undervalued — Specific catalysts, market misperception, or temporary headwinds causing the discount
- Key Risks — Macro, industry, and company-specific risks that could impair the thesis
- Estimated Intrinsic Value Range — Using DCF, comparable multiples, or asset-based approaches as appropriate
See references/output-template.md for the structured report format.
Show full SKILL.md (189 more words)Show less
Step 4: Compile and Present
Present findings in a structured report:
- Executive Summary — High-level overview of the screening results, market conditions, and thematic observations
- Screening Criteria Summary — Table of filters applied
- Individual Stock Profiles — One section per company using the output template
- Comparative Table — Side-by-side metrics for all identified stocks
- Disclaimers — Standard investment research disclaimers
Data Enhancement
For live market data to support this analysis, use the FinData Toolkit skill (findata-toolkit-us). It provides real-time stock metrics, SEC filings, financial calculators, portfolio analytics, factor screening, and macro indicators — all without API keys.
Important Guidelines
- Data currency: Always state the date/period of data used. Acknowledge any data limitations.
- Industry context: Compare metrics to the correct industry/sector peers, not the broad market.
- Qualitative overlay: Numbers alone are insufficient. Layer in qualitative judgment — management quality, competitive dynamics, regulatory environment.
- Avoid bias: Do not favor popular or well-known names. Include lesser-known companies if they meet criteria.
- Risk-first mindset: For each stock, honestly assess what could go wrong. A good screener is not a buy list.
- Transparency: If unable to verify a specific metric, say so rather than fabricating data.
