Guide

Use correlation heatmaps to identify diversification opportunities and risk clusters

  • Paste CSV data with asset names as headers and returns as rows. Values can be decimals (0.01) or percentages (1%).
  • Correlation heatmaps help identify highly linked assets (clusters) and potential diversifiers with weaker correlations.
  • Aim for balanced clusters rather than concentrating risk in one correlation cluster.
  • When correlations spike during market stress, rely on quality assets, cash, or uncorrelated factors for resilience.
  • Use at least 36–60 monthly observations or 250+ daily points for stable correlation estimates.

Frequently Asked Questions

Correlation heatmaps, portfolio diversification, and data requirements

What is a correlation heatmap in portfolio analysis?

It visualizes pairwise correlations among asset returns, helping spot clusters, diversification gaps, and potential redundancy in your portfolio.

What data format should I paste?

CSV with headers where each column is an asset and each row is a time period return. Values can be decimals (0.01) or percentages (1).

How many observations do I need?

More is better; 36–60 monthly points or 250+ daily points typically stabilize correlation estimates.

How do I interpret strong positive correlation?

Assets tend to move together, reducing diversification benefits. Consider adding assets with lower or negative correlation to improve portfolio resilience.

Can correlations change over time?

Yes. Correlations are regime‑dependent and often rise during market stress; reassess periodically to maintain effective diversification.

Are negative correlations always good?

They can hedge risk but may reduce returns. Balance correlation with expected returns and volatility when constructing portfolios.

Does scaling of returns matter?

Correlation is scale‑invariant; using decimals or percentages consistently yields the same correlations, so either format works.

How do missing values affect results?

This tool expects complete rows. For production workflows, align dates and forward‑fill cautiously, or use specialized correlation estimation methods.

What about non‑linear dependence?

Correlation captures linear co‑movement. Consider rank correlations or copulas for non‑linear relationships in advanced analysis.

How do I use this for portfolio construction?

Identify clusters and diversify across them while optimizing for risk‑adjusted return (e.g., Sharpe ratio). Use the heatmap to avoid over-concentration in highly correlated assets.
