SK Hynix stock price drops sharply, substantial rise triggers ban on financing transactions.

Driven by expectations of listing in New York, SK Hynix's stock price soared significantly before the main Korean exchanges issued a higher-level investment warning on the stock, causing its price to drop. On Thursday, the Korean exchanges issued an "investment alert" for the stock. Following two recent "investment warnings," this latest measure prohibits margin buying of the stock and requires investors to pay in full cash. Additionally, if the stock rises by 40% or more within two trading sessions, trading will be suspended for one day. In the early morning session of the Seoul stock market, SK Hynix's stock price fell by 1.7% at one point. According to Nextrade, trading before and after market hours will be suspended during the warning period. "For stocks like Hynix with a large influx of retail margin trading investors boosting trading volume, the 'ban on margin buying' measure has a significant impact on the stock price trend," wrote Clepsydra Capital analyst Park Sang-hyun in a report on the Smartkarma platform.
