DUBAI: 黑料社区鈥檚 Tadawul has introduced an equity index cap of 15 percent which is set to address concerns over the weighting oil giant Saudi Aramco will have when it lists on the exchange.
State-owned oil firm Aramco is expected to list 1.5 percent of its shares this month in a deal which could raise more than $25 billion and top the record initial public offering (IPO) of Chinese retailer Alibaba on the New York Stock Exchange in 2014.
Samba Capital, NCB Capital and HSBC 黑料社区, the joint financial advisors and joint global coordinators for Saudi Aramco鈥檚 initial offering, said on Monday that institutional bids during the first 15 days of the bookbuilding period amounted to SR144.16 billion, with 4.551 billion shares subscribed for.
The institutional bookbuilding period continues until December 4, 2019.
The Aramco IPO is seen as a test for the Saudi exchange, where the largest listing so far has been worth $6 billion.
鈥淎ny constituent whose index weight reaches or exceeds the threshold will be capped in accordance with the set limit,鈥 Tadawul said in a statement on Monday.
The move is part of a broader update of Tadawul鈥檚 index methodology, including a revision of the free float shares calculation methodology for shares owned by government entities.
The new measures will 鈥渆nsure more balanced indices, which will accurately represent the movement of the market, enhance disclosures and transparency and minimize securities鈥 dominance,鈥 Tadawul鈥檚 CEO Khalid Al-Hussan said in a statement.
Tadawul also said it has applied a new 鈥淔ast Entry鈥 rule allowing shares of IPOs to be included in the all-share equity index at the close of the fifth trading day.
The updates will be effective by the end of the year.
