These move in the same direction about 56% of the time
Their swing sizes only faintly line up (~1% of the pattern is shared).
A faint pattern — interesting as colour, not strong enough to act on alone.
On a log scale so equal % moves take equal vertical space — best when one series has grown much faster than the other.
What to Watch
HPE moves ~6 days before NAKA
Watch HPE for an early read on NAKA.
Holds in both up and down markets
The relationship is similar whether prices are rising or falling — reliable in both directions.
Mostly stable
The relationship drifts a little but stays in the same neighbourhood.

Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.

NAKA shifted 6 days earlier. Reads: "Does Hewlett Packard Enterprise Co. (HPE) today line up with NAKA 6 days from now?"

Baseline
+9%
No-shift correlation, matching the main time-series chart above.
Peak shift
+6 days
-15%
A non-zero peak suggests one series lines up better when shifted against the other.
Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
Do They Crash Together?
How these series behave when markets are rising, falling, or diverging. A correlation that holds in drawdowns is very different from one that only works in rallies.
