Two series that should have nothing to do with each other
Surprise me
GLOVIZ picked Day-ahead power price DE from Energi Data Service (Energinet) and Temperature Lagos from Open-Meteo, paired them on time, and found a correlation of -0.508 over 250 matched observations. Two different institutions, two different measurement programmes, no shared mechanism. That is the point: with a thousand series, coincidences are cheap.
