How South Korea’s tech rout hit Hong Kong – and why regulators stepped in
Following an 80 per cent plunge in a popular SK Hynix leveraged fund, authorities have moved to overhaul rules for some high-risk investments

South Korea’s roller-coaster market, driven by sharp swings in semiconductor giants Samsung Electronics and SK Hynix this year, has also reverberated in Hong Kong, where suspected fund embezzlement by a loss-making investment manager and outcry from leveraged-product investors have made headlines.
The product surged to an all-time high of HK$193.65 (US$24.69) in late June, with its market capitalisation briefly surpassing HK$130 billion (US$16.57 billion) – making it Hong Kong’s largest ETP – before collapsing 80 per cent since the start of July.
The sharp decline tracks a broader sell-off in South Korea, where the Kospi index tumbled more than 11 per cent on Tuesday, triggering its eighth circuit breaker this year. The index also fell below 6,000 points for the first time since April 14, and is now down more than 35 per cent from its June peak.
