Pan-Asia Index Rebalances/ Events/ Delta One

Event-Driven

The Stock Exchange of Thailand (SET) has commenced a market consultation on changing the <a href="https://www.smartkarma.com/entities/stock-exchange-of-thailand-set-50-index" target="_blank" data-smartkarma-citation="entities:31493:1" rel="noopener">Stock Exchange of Thailand SET 50 Index (SET50 INDEX)</a>, SET100 and SETHD indices to free float market cap weighted indices from the upcoming rebalance in June.The market consultation document is short on detail, but the main points are the change in index calculation from full market cap weighted to free float market cap weighted, implementation of the changes in two tranches at the June and December reviews, and implementation of quarterly changes in free float for moves of +/-5%.The biggest uncertainty for us is whether the selection of the stocks for inclusion/exclusion will use the full market cap or the free float market cap.Using the full market cap for stock selection could see 3 changes at the upcoming June review, while using free float market cap for stock selection could result in up to 6 changes at the review. The two step implementation of the free float changes will dampen the index turnover but it will still be relatively high, ranging from a one-way turnover of 7.8% for changes in free float only to 9.52% if the stock selection methodology uses free float market cap.In this Insight, we look at the proposed changes and enumerate three scenarios, the changes they will entail, the impact on the stocks and the turnover for each scenario.
