These move opposite each other about 46% of the time
Their swing sizes only faintly mirror each other (~0% of the pattern is shared).
Roughly random — these don't track each other in a meaningful way.
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
COPX moves ~4 days before USD/HKD Exchange Rate
Watch COPX for an early read on USD/HKD Exchange Rate.
Holds in both up and down markets
The relationship is similar whether prices are rising or falling — reliable in both directions.
Rock solid
The relationship barely changes from period to period — treat it as a reliable signal.

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 4 days earlier. Reads: "Does COPX today line up with USD/HKD Exchange Rate 4 days from now?"

Baseline
-7%
No-shift correlation, matching the main time-series chart above.
Peak shift
+4 days
+12%
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.
