(S-Chips or non S-Chips) groups
• Announcements were custom-categorized for more granular analysis: 4 SGX categories and 60 sub-categories re-grouped under 15 custom categories and 106 sub-categories. The study was done across three forms of returns and for multiple cumulative holding periods, pre- and post-announcement.
