us-etf-flow

us-etf-flow is a skill for Claude Code, Codex from skloxo/TideTrading. It costs 38 tokens per session (2,753 once invoked), scanned A, a copy of us-etf-flow, MIT.

A workflow for analysing money moving through US exchange-traded funds, or ETFs. ETFs are funds traded like stocks; their creations and redemptions can show institutional allocation, while sector breadth and style flows show where demand is spreading.

In plain words
What is it for?
Use it to track ETF inflows and outflows, compare sectors, assess risk appetite, and study rotation between investment styles and themes.
Why use it?
ETF price changes alone do not show how much new money entered or left. Flow and breadth data help separate broad institutional positioning from movement concentrated in a few stocks.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

us-etf-flow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

US ETF Flow & Sector Breadth Analysis

Overview

Track capital flows through US ETFs to identify institutional positioning, sector rotation trends, and risk appetite shifts. ETF flows are a real-time proxy for institutional capital allocation — unlike 13F filings (45-day lag), ETF creation/redemption data is available daily.

Core Concepts

1. ETF Flow Mechanics

Creation / Redemption process:

  • Inflows (creation): Authorized Participants (APs) deliver baskets of underlying securities to the ETF issuer → receive new ETF shares → sell on exchange. This happens when ETF trades at a premium to NAV.
  • Outflows (redemption): APs buy ETF shares on exchange → redeem with issuer for underlying securities → sell securities. This happens when ETF trades at a discount to NAV.
  • Signal interpretation: sustained large inflows = institutional demand; sustained large outflows = institutional liquidation.

Key distinction:

  • ETF price movement ≠ ETF flow. Price can rise on low volume (momentum). Flows require actual capital commitment.
  • Flows are a quantity signal (how much money is moving), not a price signal.

2. Major ETF Flow Categories

Broad Market ETFs
ETF Tracking Index AUM Flow Signal
SPY S&P 500 ~$500B Broadest equity risk appetite
IVV S&P 500 ~$400B Long-term institutional allocation
VOO S&P 500 ~$400B Retail + advisor allocation
QQQ Nasdaq 100 ~$250B Tech / growth appetite
IWM Russell 2000 ~$60B Small-cap risk appetite
DIA Dow Jones 30 ~$30B Value / blue-chip sentiment

Interpretation rules:

# Broad market flow signals
if spy_flow > 0 and iwm_flow > 0:
    signal = "risk_on"  # Both large and small cap getting inflows
elif spy_flow > 0 and iwm_flow < 0:
    signal = "quality_flight"  # Money rotating to large-cap safety
elif spy_flow < 0 and iwm_flow < 0:
    signal = "risk_off"  # Broad equity outflows
elif spy_flow < 0 and iwm_flow > 0:
    signal = "risk_seeking"  # Rotation from large to small (rare, usually early cycle)
