These move in the same direction about 52% of the time
Their swing sizes only faintly line up (~1% of the pattern is shared).
Roughly random — these don't track each other in a meaningful way.
Both lines start at the same point — easy to compare when growth rates are similar.
What to Watch
USD/HKD Exchange Rate moves ~3 days before XYZ
Watch USD/HKD Exchange Rate for an early read on XYZ.
Holds in both up and down markets
The relationship is similar whether prices are rising or falling — reliable in both directions.
Mostly stable

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.

+5% stronger than no-shift baseline
USD/HKD Exchange Rate shifted 3 days later. Reads: "Does XYZ today line up with USD/HKD Exchange Rate 3 days ago?"
316 overlapping points at this shift
Baseline
+8%
No-shift correlation, matching the main time-series chart above.
Peak shift
-3 days
+13%
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.
