China's securities regulator stopped displaying real-time data for flows into Chinese A-shares through Hong Kong on Monday - a move deemed to align with the common practice of the world's other stock markets.

Under the new arrangement, live trading data for flows from Hong Kong to Shenzhen and Shanghai bourses via the Northbound Stock Connect system, are no longer available from Monday. Turnover details will be announced after the close of daily trading sessions.

This latest move came after successful testing announced by the Hong Kong Exchanges and Clearing Limited (HKEX) on Saturday, according to China Securities Journal.

Industry insiders believe that the adjustment is expected to reduce abnormal market swings and mitigate the so-called "herd" behavior in trading.

The Shanghai, Shenzhen, and Hong Kong Stock Exchanges announced on April 12 the simultaneous adjustment of the disclosure mechanism for the Stock Connect regime, with the disclosure practices adjustment being the focal point among investors.

According to media reports, a daily quota balance equal to or exceeding 30% is labeled as "sufficient", while below 30% prompts disclosure of the quota balance in the Stock Connect.

In the Shanghai-Shenzhen Stock Connect, on the fifth trading day of each quarter, mainland investors' cumulative holdings and each Hong Kong Clearing Participant's holdings for the previous quarter are disclosed. Similar disclosure standards apply to the Hong Kong Stock Connect quota balance - with daily disclosure of Stock Connect investors' total individual securities holdings after market close.

Moreover, the exchanges outlined a two-phase adjustment plan to ensure smooth market transition and adequate preparation time for all stakeholders.

The second phase will see simultaneous adjustments across the Shanghai, Shenzhen, and Hong Kong exchanges for other trading data disclosure, expected three months after the first phase's completion. The objective is to streamline market operations and bolster transparency.

The exchanges stated in April that they collaborated closely under regulatory guidance to optimize the Stock Connect programs. Moving forward, the exchanges plan to further expand eligible securities and trading methods, balancing trading transparency and security.

Market analysts highlighted the efficiency of the new disclosure arrangements, which streamline both intraday and after-trading-session information. The adjustments align disclosure practices with domestic public fund requirements, ensuring consistency and enhancing adaptability to market dynamics.

The new arrangement aims to promote fairness in investor access to information and encourages attention to signals associated with northbound fund flows, China Securities Journal cited Yu Mingming, Chief Analyst of Financial Engineering and Financial Products at Cinda Securities, as saying.
