What it does
Insider Trading Analyzer is an agent skill from Geeksfino/finskills. Analyze insider trading patterns to surface companies with significant, meaningful insider buying activity. Use when the user asks to review insider trading activity, find stocks insiders are buying, analyze SEC Form 4 filings, detect insider buying clusters, assess management confidence through insider purchases, or identify bullish insider signals in a sector or industry.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/insider-signal-criteria.md` and `references/output-template.md`).
It sits in Business, Finance & HR, covering Trading and backtesting. 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 review insider trading activity
- Find stocks insiders are buying
- Analyze SEC Form 4 filings
- Detect insider buying clusters
Example prompts
- “/insider-trading-analyzer”
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 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
Insider Trading Analyzer loads about 1.2k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 587 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.

Insider Trading Pattern Analyzer
Act as a professional insider trading analyst. Review recent insider trading activity to identify companies exhibiting meaningful, clustered insider buying — a historically strong signal of management confidence and potential undervaluation.
Workflow
Step 1: Define Scope
Confirm with the user:
- Sector or industry — specific sector (e.g., Technology, Healthcare) or broad market scan
- Time window — default: last 90 days; user may widen or narrow
- Number of results — default: top 5 companies
- Market scope — US (SEC Form 4), international, or both
- Insider roles of interest — all insiders, C-suite only, directors only, or 10%+ beneficial owners
If the user wants defaults, proceed with: all US sectors, 90 days, top 5, all insider roles.
Step 2: Apply Insider Buying Filters
Screen for companies matching ALL of the following criteria. See references/insider-signal-criteria.md for detailed thresholds and edge cases.
| Filter | Criterion |
|---|---|
| Cluster buying | Multiple insiders (≥ 2) buying within the time window |
| Transaction type | Open-market purchases only (exclude option exercises, grants, automatic plans) |
| Recency | Purchases within the last 90 days (or user-specified window) |
| Meaningfulness | Purchase size meaningful relative to insider's compensation and existing holdings |
Step 3: Rank and Analyze
Rank qualifying companies by signal strength using these factors (see references/insider-signal-criteria.md for scoring details):
- Number and seniority of insiders buying
- Aggregate dollar value of purchases
- Purchase size relative to insider compensation
- Buying into price weakness (contrarian signal)
- Cluster density (multiple buys within a narrow window)
Step 4: Deep-Dive on Top Results
For each of the top companies, provide a detailed analysis covering:
- Who is buying and how much — Name, title, number of shares, dollar value, dates, and what percentage of their holdings the purchase represents
- Historical impact — How insider buying has preceded stock performance in this specific company's history
- Management confidence signal — What the buying pattern likely signals about management's view of the company's prospects
- Potential red flags — Reasons the buying might not be as bullish as it appears
See references/output-template.md for the structured report format.
Show full SKILL.md (257 more words)Show less
Step 5: Compile and Present
Present findings as a structured report:
- Executive Summary — Overview of insider activity trends in the scanned sector/market
- Methodology — Filters applied, time window, data sources
- Individual Company Profiles — One section per company using the output template
- Comparative Table — Side-by-side insider buying metrics
- Disclaimers — Insider trading data interpretation caveats
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
- Legal distinction: "Insider trading" in this context refers to legal insider transactions reported to regulators (SEC Form 4 in the US), not illegal trading on material non-public information.
- Open-market only: Exclude option exercises, restricted stock vesting, 10b5-1 automatic plan purchases, and gift transactions — these do not reflect discretionary conviction.
- Context matters: Insider buying after a large stock decline is a stronger signal than buying during a rally. Always note price context.
- Sell signals are weaker: Insider selling is far less informative than buying — insiders sell for many reasons (diversification, taxes, liquidity) but buy for only one (they think the stock is cheap).
- Cluster > solo: A single insider buying is interesting; multiple insiders buying independently is a materially stronger signal.
- Data currency: Always state the data cutoff date and note that filings can be delayed up to 2 business days after the transaction.
- Not a buy recommendation: Insider buying is one signal among many. Always frame findings as informational, not as investment advice.
