What is stock market correlation?

How is correlation typically measured?
Often with the Pearson correlation coefficient, which assesses linear relationships; Spearman rank is used for non-linear or ordinal relationships.
How does correlation affect diversification?
High positive correlation means assets move together, offering less diversification; low or negative correlation improves diversification benefits.
What should you be cautious about when interpreting correlations?
Correlation does not imply causation, relationships can change over time, and outliers or non-stationary data can distort results.
What is a correlation matrix and how is it used?
A table of pairwise correlations for multiple assets; helps identify relationships to enhance diversification and hedging decisions.
