Semilux shares surge 21.03% intraday after announcing business combination with Taiwan Color Optics and Chenghe Acquisition Co.

Semilux International (NASDAQ:SELX) surged 21.03% intraday following a trading halt triggered by a "LULD pause" at 03:02 PM on February 16, 2024. The Limit Up-Limit Down (LULD) mechanism, designed to curb extreme volatility, temporarily suspended trading after the stock’s price spiked sharply. While no specific news event was disclosed during the halt, such pauses often indicate abrupt price movements driven by large trades, algorithmic activity, or unconfirmed market rumors. The intraday rally suggests a sudden influx of buyer demand, potentially linked to undisclosed developments or speculative trading, though no direct catalyst was explicitly reported in the provided news.
