ASW ex dividend date was 06/02/2019.
The sudden pop to $0.75 on 05/02/2019 was most likely due to somebody being not patient enough and wants to capture the $0.02 interim dividend.
Personally, I find paying up $0.09 (from $0.66 to $0.75) to capture $0.02 dividend, hard to understand. Maybe it's Kim Chong himself.
