FAQPage Schema
How do I track institutional capital flows without the 45-day lag of 13F filings?

Analyze daily ETF creation and redemption activity to track institutional capital flows in real-time. This approach provides a current proxy for institutional positioning, avoiding the 45-day reporting lag inherent in traditional 13F filings.

How do I identify sector rotation trends using ETF flow data?

Identify sector rotation trends by calculating sector breadth and cyclical-to-defensive ratios from ETF flow data. This analysis reveals current market cycle phases and institutional positioning across various sector-based ETFs.

What is the best way to measure institutional risk appetite in the market?

Measure institutional risk appetite by analyzing ETF creation and redemption data across broad market and factor-based ETFs. Inflows into cyclical sectors indicate risk-on sentiment, while redemptions and defensive rotation into staples signal risk-off positioning.

Can I use yfinance to analyze ETF creation and redemption data?

Yes, you can use yfinance to retrieve the necessary ETF data for analyzing creation and redemption activity. This dependency provides the daily flow metrics required to quantify institutional capital allocation and sector rotation trends.

How do I calculate cyclical versus defensive positioning from ETF flows?
