This divergence has lasted for some time now:

Something will have to correct... But which one?
Or is it just an opportunity for a convergence trade without trying to guess the direction?
Was the yesterday's funny WIG20 action a signal of the future developments?
Questions, questions and more questions... :)
Nevertheless, it's worth keeping in mind that even though Polish and US markets are highly correlated, correlation is not a stable measure. It's much safer to check the spread between the markets based on their cointegration.
Last but not least, S&P500 remains decoupled from the wider risk assets context model.
