Definition
From -1 to +1, how far two assets move together.
Why it matters
Measuring risk means knowing how much you can lose and how far results can stray from average: without it, a return means nothing.
How to read it in the news
A risk measure is always read with its horizon (day, month, year) and over a period long enough to include crises.
