Asset correlation measures how closely two prices move together over time. A correlation near +1 means the assets tend to rise and fall together. A value near −1 means when one rises the other tends to fall — useful for hedging. A value near 0 means their price movements are largely independent. This tool uses Pearson correlation calculated from daily average prices stored in our own database.
