What to Watch Next Week
Every theme was strong for only one day, so the open question is whether any of them lasts. AI & Robotics was the last to move, rising 6.14% on May 24.
Policy news is also worth following. A 2019-05-20 headline said the household progressive power tariff would be revised before summer, and it came out the same day Summer Season rose.
