SK Hynix plunges 30% again in pre-market trading on Nextrade within a week, sparking doubts over volatility on alternative trading platforms

```html(1) On Thursday at 8 a.m., SK Hynix traded 11 shares at 1,168,000 won per share in pre-market trading on Korea’s alternative trading platform Nextrade, plunging 30% from the previous day's closing price and hitting the daily limit. By the end of the 50-minute pre-market session, the decline narrowed to around 2%. (2) This sharp drop was directly related to the previous trading day’s poor earnings outlook from US storage chip company SanDisk, whose after-hours stock price plummeted, causing Korean chip stocks to fall as well. During regular trading hours in the Korean stock exchange that morning, SK Hynix shares once dropped 9.8%. (3) This trend is highly similar to last Tuesday — at that time, SK Hynix also saw a 30% plunge in pre-market trading on Nextrade before narrowing the losses. The occurrence of two similar abnormal fluctuations in a short period has triggered widespread market doubts over the price volatility mechanism and liquidity of the Nextrade platform.```
