I've been trying to get a handle on the interplay between $NIKKEI and $HSI, and more broadly, how they're reacting to moves in the S&P. It feels like the traditional correlations I learned about are either less pronounced or flipping faster than I can track. For instance, you'd expect a strong lead or lag, but lately, it's almost disjointed. Am I overthinking this, or have others noticed a similar breakdown in how these Asian indices typically move in relation to each other and Western markets?
