“暴涨63%又闪崩收跌”！一颗“新药”引爆板块

Core Viewpoint - The recent volatility in the Hong Kong innovative drug sector, particularly the extreme price fluctuations of Yaojie Ankang-B (2617.HK), has raised questions about the rationale behind its inclusion in major indices despite lacking revenue and being newly listed [3][10]. Group 1: Stock Performance and Market Reaction - Yaojie Ankang experienced a dramatic stock price increase of over 550% within six days, reaching a market capitalization of HKD 164.7 billion, entering the "billion-dollar club" [7][8]. - On September 16, the stock saw a "bungee jump" pattern, soaring over 63% before closing down 5.73%, with a total intraday fluctuation of nearly 124% [6][7]. - Following this volatility, several innovative drug ETFs, including the Silver Hua National Innovation Drug ETF, fell by 2.98%, leading the decline in cross-border ETFs [5][6]. Group 2: Inclusion in Indices and Controversy - The inclusion of Yaojie Ankang in the National Innovation Drug Index raised concerns, as the company had been listed for less than three months and reported no revenue, with a pre-tax loss of HKD 123 million for the first half of the year [10][11]. - The index's criteria for inclusion require companies to have no significant violations or financial issues, which Yaojie Ankang did not meet due to its lack of operational history and ongoing product development [10][11]. - The rapid inclusion of new stocks in indices has sparked debate, particularly regarding the impact on passive investment products that must track these indices, leading to significant volatility in their net asset values [12][13].
