SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you systematically evaluate and compare ETFs so you can choose products that match your investment goal while controlling tracking error, fees, liquidity risk, and premium/discount behavior.

Core Features & Use Cases

  • ETF classification &结构理解: Break down ETFs by underlying assets and structure (plain, LOF,联接基金,杠杆/反向) to avoid mismatched use cases.
  • Core metrics framework: Compute and interpret tracking error, information ratio, 折溢价率, liquidity indicators, and fee drag for decision-grade comparisons.
  • Quant decision models & strategies: Provide a repeatable selection/scoring approach plus portfolio construction (core-satellite), rotation ideas, factor exposure analysis, and practical ETF套利 logic.
  • China market operational considerations: Address A-share ETF mechanics, QDII-specific risks (limits and FX), and how these affect implementation and expectations.
  • Data-driven templates (Tushare-based): Offer code templates for retrieving ETF list/nav/daily/index data and calculating tracking error, premium/discount monitoring, and fund flow approximations.

Quick Start

Ask to analyze the ETFs tracking the same index by comparing规模、费率、近1年跟踪误差、日均成交额与买卖价差, then output a ranked recommendation for your intended holding period.

FAQPage Schema
How do I compare ETFs tracking the same index using tracking error and fee drag?

To compare ETFs tracking the same index, evaluate tracking error, fee drag, liquidity, and premium/discount behavior. This ETF analysis methodology applies a quant decision model to score and rank products based on metrics like scale, fees, and daily trading volume for your intended holding period.

What is the best way to assess ETF liquidity risk and premium/discount behavior in China's market?

Assessing ETF liquidity risk and premium/discount behavior in China's market involves monitoring daily trading volume, bid-ask spreads, and structural mechanics specific to A-share and QDII ETFs. This framework calculates these liquidity indicators to identify implementation risks and approximate fund flows for practical arbitrage checks.

How do I calculate ETF tracking error using Tushare data templates?

Calculate ETF tracking error using Tushare data templates by retrieving ETF list, NAV, daily, and index data. These code templates compute tracking error metrics and monitor premium/discount rates to provide decision-grade comparisons across different ETF types and index families.

Can I use ETF analysis for core-satellite portfolio construction and factor exposure assessment?

Yes, you can use ETF analysis for core-satellite portfolio construction and factor exposure assessment. The framework provides quant decision models that support portfolio construction, rotation screening, and factor exposure analysis to align ETF selection with your specific investment goals and risk tolerance.

Does this ETF comparison framework account for QDII-specific risks like FX limits?

Yes, this ETF comparison framework accounts for QDII-specific risks including FX limits and operational constraints. It addresses how A-share ETF mechanics and QDII-specific structural risks affect implementation expectations, ensuring your ETF selection avoids mismatched use cases across different underlying assets.

When should I not use plain ETFs versus LOF or leveraged structures for investment goals?

Avoid mismatched ETF structures by classifying underlying assets and structure types including plain, LOF, 联接基金, and leveraged/inverse ETFs. Understanding these structural differences prevents inappropriate use cases and ensures your ETF selection aligns with your specific portfolio construction and risk management requirements.
