How this service works
Xynaptic Crypto Correlation — Pearson correlation matrix of daily returns for 2-5 coins over 90 days: the honest diversification check. GET ?coins=bitcoin,ethereum,solana.
Output
A Pearson correlation matrix where each cell contains the correlation coefficient (ranging from -1 to +1) between the daily returns of two specified coins over a 90-day lookback period. Values near 1 indicate coins moving together; values near 0 or negative indicate low or inverse co-movement, useful for diversification decisions.
Example use cases
Portfolio diversification sanity check
“I'm holding bitcoin, ethereum, and cardano — can you pull the 90-day correlation matrix so I can see if any of them are actually diversifying my risk?”
Evaluating a new coin addition
“I'm thinking of adding solana to my BTC and ETH portfolio — can you check the correlation between all three over the past 90 days to see if solana actually adds diversification?”
Identifying uncorrelated crypto pairs
“Which of these five coins — bitcoin, ethereum, solana, avalanche, and polkadot — are least correlated with each other? Run the Pearson correlation matrix on all of them.”
