A significant financial loss of over NT$450 million (approximately US$14.7 million) has been incurred by National Investment Fund (國泰投信) due to insider trading violations. Kuo Ming-chien, who concurrently served as an independent director at World Semi (世芯KY), is implicated in the scandal.

Kuo allegedly used his position to benefit personal investments, violating regulations concerning individuals with access to confidential company data. The incident has prompted scrutiny of internal controls and compliance procedures within the fund. Authorities are investigating the extent of the violations and potential legal repercussions for those involved. This case highlights the risks associated with conflicts of interest and the importance of maintaining market integrity.
