Correlation is not binary, it’s on a 0-100% scale.

More like -100% (perfectly anti-correlated) to +100% (perfectly correlated) through 0% (perfectly decorrelated) and everything in between!
Correct my bad, this is important :)
Also, correlation changes all the time, and sadly tends to converge on the way down, but not up.
