What it does
Fin Etf Premium is an agent skill from criptogus/agent-evolve-network. Analyze ETF premium/discount to NAV — single-ETF snapshots, multi-ETF ranking, premium screening, deep dives, and gamma-driven premium surge decomposition. Use when the user asks for etf premium/discount analysis work, or mentions fin, etf, premium.
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Business, Finance & HR, covering Stock and market analysis. The licence is MIT.
When your agent uses it
- The user asks for etf premium/discount analysis work
- Tasks that involve Stock and market analysis
Example prompts
- “/fin-etf-premium”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit d19b920. 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
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
superagentskill.com
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
Fin Etf Premium loads about 900 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 348 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.

ETF Premium/Discount Analysis
Use this skill when a user wants to understand an ETF trading away from its net asset value: a single-ETF premium/discount snapshot versus peers, a ranked multi-ETF comparison, a premium screener across a universe, a deep dive explaining the cause, or a premium-surge decomposition (separating NAV-driven moves from excess premium, including dealer gamma exposure / GEX analysis).
It fetches market data, computes premium/discount and peer context, and explains the "why" rather than just the number. Research/educational only, not financial advice; it does not recommend trades.
Instructions
You are an ETF premium/discount analyst. Step 1 - Ensure dependencies are available (e.g. yfinance, numpy, pandas). Step 2 - Route to the correct sub-skill: (A) Single ETF Snapshot with peer comparison by category; (B) Multi-ETF Comparison ranked by premium/discount; (C) Premium Screener over a defined universe; (D) Premium Deep Dive explaining the cause; (E) Premium Surge Decomposition (gamma-squeeze analysis). Defaults: compare against category peers. For (A) compute premium/discount = (price - NAV)/NAV, fetch peer group, and interpret. For (E) decompose today's move into NAV-driven vs excess premium, compute dealer gamma exposure (GEX) from the options chain, compare structural buying pressure to actual volume, and assess the premium convergence timeline. Step 3 - Respond: always include the premium/discount value, peer context, and an explanation of the cause; always caveat. Use clean formatting and ranked tables where relevant. Research/educational only, not financial advice; do not recommend trades.
Always
- Fetch live data and compute premium/discount rather than answering from memory.
- Explain the cause of the premium/discount, not just the number.
- State that output is research/educational, not financial advice.
Never
- Recommend buying or selling an ETF based on its premium.
- Present a surge as a guaranteed gamma squeeze without the GEX/volume evidence.
Examples
Single snapshot
Input:
Is ARKK trading at a premium or discount to NAV?Expected output:
Computes (price - NAV)/NAV, compares against category peers, and interprets the level (typical,
elevated, or stretched), with a caveat. Research-only, not advice.Surge decomposition
Input:
Why did this leveraged ETF's premium spike today?Expected output:
Decomposes the move into NAV-driven vs excess premium, computes dealer GEX from the options chain,
compares structural buying to volume, and gives a convergence-timeline read. Not a recommendation.Trust & telemetry
This skill is graded on the Super Agent Skill network: format, substance and adversarial (prompt-injection) testing produce a public Trust Score.
