HSTECH Index Rebalance: BYD (1211 HK) To Replace China Literature (772 HK) As Trade Hits US$6bn
- As expected, BYD (1211 HK) will be added to the Hang Seng TECH Index (HSTECH INDEX) in June following the launch of God’s Eye, its Advanced Driver-Assistance System (ADAS).
- BYD (1211 HK)‘s inclusion results in China Literature (772 HK) being deleted from the index. China Literature stock should drop over the near-term.
- Estimated one-way turnover at the rebalance is 13% resulting in a round-trip trade of HK$46.5bn (US$5.95bn). There are 16 stocks that have at least 1x ADV to trade from passives.
[Japan Buybacks] ¥7.3trln of Buybacks Announced In the Last Month – Data on Each, Plus History
- Buybacks are a central part of Corporate Japan’s effort to improve corporate/capital governance. Lots of cross-holders want/need to sell. Lots of companies want to reduce excess equity.
- This earnings season has seen a LOT of new buybacks announced. ¥7.3trln in the last month and that doesn’t even include the biggest buybacks extant by March-end companies.
- We are experimenting with new ways of displaying data/analytics for buybacks in Japan. To that end, we have a new tool. We hope users find it useful. We invite feedback.
Alibaba (BABA): 4Q25, Main Business Growth Recovered to 12% YoY, Buy

Hang Seng Index (HSI) Rebalance: Midea (300 HK) & ZTO Express (2057 HK) Added; Inching Towards a 100
- Midea Group (300 HK) and ZTO Express Cayman (2057 HK) will be added to the Hang Seng Index (HSI INDEX) in June to take us up to 85 index constituents.
- Estimated one-way turnover is 2.9% and the estimated round-trip trade is HK$11.3bn (US$1.44bn) with over 1x ADV to trade in the adds and in one stock with a FAF increase.
