What to Watch Next Week
The data covers one session, so each theme had just one strong day. For Media & Content, the open question is whether the ‘Sweet Home’ effect cited in the news lasts beyond Dec 28.
In System Semiconductors, one headline reported institutional net buying in DB HiTek for 5 consecutive days. The COVID-19 theme moved alongside news coverage of AstraZeneca.
