3119.HK is trading at HK$153.75, down 3.12%, as Asian equities weakened amid mixed megacap earnings and declines in Samsung Electronics and SK Hynix. - On October 22, rising oil prices and concerns that escalating Middle East hostilities could disrupt supply added to risk aversion. - This contrasts with the previous session’s AI-driven chip rebound, after Super Micro’s upbeat revenue guidance boosted semiconductor shares. The decline appears consistent with a reversal in regional risk appetite, rather than a new ETF-specific catalyst.
