Correlation Matrices
A correlation matrix is a statistical tool used to quantify the degree to which the price movements of multiple assets are related to one another. Each cell in the matrix represents the correlation coefficient between two assets, typically ranging from negative one to positive one.
In quantitative finance, these matrices are foundational for constructing portfolios and calculating Value at Risk. In the crypto domain, these matrices are frequently unstable, as assets often move in lockstep during market crashes but decouple during bull runs.
Traders use these matrices to determine if their hedging strategies are actually providing the intended protection. When the matrix shows high correlation across all assets, it indicates that diversification benefits are currently minimal.
