These move in the same direction about 64% of the time
Their swing sizes loosely line up (~23% of the pattern is shared).
A real but noisy link — useful as context, risky as a standalone signal.
On a log scale so equal % moves take equal vertical space — best when one series has grown much faster than the other.
