Horizon Robotics (9660 HK): Southbound Stock Connect Inclusion Today & Upcoming Index Flows
- Horizon Robotics (9660 HK) will be added to Southbound Stock Connect from the start of trading today. Then there will be passive buying at the close on 20 June.
- The lock up expiry in April will result in large buying from trackers of the Hang Seng TECH Index (HSTECH INDEX) and HSIII Index in September.
- The stock will also be added to another large global index, though the timing on inclusion is not certain at the moment.
Tsuruha (3391 JP)/Welcia (3141 JP): Vote Musings
- Leading proxies recommend that Tsuruha Holdings (3391 JP) shareholders vote against the Tsuruha/Welcia Holdings (3141 JP) merger on 26 May.
- The share exchange terms favour Welcia over Tsuruha shareholders. The Tsuruha vote will be close but likely to be approved. Long Tsuruha is the trade, irrespective of the vote.
- For a vote pass, you are long synergies and a likely partial offer bump. For a fail, you are long an undemanding multiple and the optionality of a new bid.

Zomato/Eternal: The BIG Passive Selling Starts
- Following shareholder approval of the proposal to reduce the Foreign Ownership Limit from 100% to 49.5%, NSDL has updated the FOL. This starts the process of passive selling in Zomato.
- Passives will sell US$350m at the close on Tuesday. There is a low probability of more selling later in the week. There will be bigger selling in August.
- The size of the selling in August and beyond will depend on what foreign investors do in the stock till the end of June. Watch the red flag/ breach list.
Clarifying a Few Points of Confusion Surrounding the Samsung Biologics Spin-Off
- Will the newly listed spinco also IPO Samsung Bioepis? That’s a textbook ECO — and could spark shareholder value dilution concerns, regulatory pushback, or even a potential KRX block.
- The 8% dip looks tied to IPO fears around Bioepis. If Samsung hard-locks its no-IPO stance and FSS signs off, a near-term bounce in Biologics could be in play.
- Post-Listing, watch for Samsung C&T to shift exposure—potentially boosting the surviving company’s value while capping the spinco. Sets up a compelling relative-value trade worth positioning for.
Underwriting Returns: A Risk Arb Look at Helvetia-Baloise
- Shareholders of both firms have approved the merger, clearing a critical milestone ahead of expected regulatory clearance by late Q3 2025.
- CHF 400m in net synergies and potential capital optimization could lift 2028 ROE to nearly 16%, offering meaningful value creation.
- I recommend a long Baloise / short Helvetia strategy to capture the current 1.2% spread, translating to an estimated 3.4% annualized return.
