How to Evaluate Clean ETFs

Fund Performance

  1. Historical Returns: Review the historical returns of the ETF to assess its past performance, though past performance is not indicative of future results.

  2. Risk-Adjusted Performance: Analyze metrics such as the Sharpe ratio to evaluate the ETF's performance in relation to its risk exposure.

  3. Tracking Error: Examine the tracking error to understand how closely the ETF's performance matches its underlying index or benchmark.

Fund Holdings

  1. Asset Allocation: Investigate the ETF's portfolio composition to ensure it aligns with your investment objectives.

  2. Sector Exposure: Analyze the ETF's exposure to different sectors to determine its diversification and risk profile.

  3. Geographic Diversification: Evaluate the geographic distribution of the ETF's investments to assess its exposure to various regions and potential risks.

Expense Ratio

Consider the ETF's expense ratio, as higher fees can erode returns over time.

ESG Ratings

  1. Independent Ratings Agencies: Consult ratings from independent agencies such as MSCI, Sustainalytics, or Morningstar to gauge the ETF's ESG performance.

  2. ESG Scores and Controversies: Examine the ETF's ESG scores and any controversies surrounding its holdings to ensure the fund aligns with your values and expectations.
