South Korea's KOSPI reports its biggest drop since early March, as chipmakers slump

South Korean shares fell nearly 11% in their 'worst session for about five months' on Tuesday, as a global chipmaker selloff?hammered SK Hynix, Samsung Electronics and CXMT, while CXMT’s stellar debut in the market heightened concerns about Chinese competition.

The benchmark KOSPI fell 732.09 or 10.84% to 6,023.66, its largest daily loss since the 4th of March, when the index experienced a record drop following the outbreak of the Iran War.

The price fell by as much as 11.3% in one day and triggered a circuit breaker, the 14th time in history. The price also fell below 6,000 for the first time since last April.

KOSPI is down 29% this month, surpassing its previous monthly record of?27% from October 1997. The KOSPI is down 34% since the peak in June of 9,114.55, but it's still up 43% for the year.

SK Hynix, a memory-chip manufacturer, fell 14.7%. after its American Depositary Receipts (ADRs), which are listed on the New York Stock Exchange and have dropped below their.original U.S. Offering Price. Samsung Electronics fell 14.4%, its largest daily loss since Oct. 2008.

These two chipmakers are responsible for more than 50% of the KOSPI weighting. This amplifies the impact of a sector-wide decline on the market. SK Hynix, Samsung and other companies are expected to release their earnings for the second quarter later this week.

The market sentiment was further dampened due to developments in China. This included the blockbuster debut of ChangXin Memory Technologies, (CXMT), and reports that a Chinese firm backed by the state has started producing immersion DUV equipment.

The market is more concerned about CXMT's potential to expand its?capacity and develop technology in the future than its current earnings, said Kim Seok Hwan, a Seoul-based analyst at Mirae Asset Securities.

South Korea's top regulator of financial services said that if necessary, authorities would consider a limit on leveraged ETF investments for retail investors, since these have increased market volatility ever since they were introduced in May.

Retail investors purchased 4 trillion won, while foreigners sold 5 trillion won.

Only 36 of the 917 issues traded advanced while 878 declined.

On the onshore settlement platform for settling trades, the won was quoted 0.2% higher than before at 1,462.5 dollars. This erased early losses of up to 0.5%. Traders attributed SK Hynix's dollar sales in relation to the sale of its U.S. shares to the gains. (1 dollar = 1,462.2000 won).
