澜起科技的"惊魂三日"

澜起科技在7月15日至17日短短三个交易日内遭遇股价暴跌。1股价从15日的275元开始下挫，16日跌幅达16.44%，17日再下跌13.04%，三天累计跌幅超过30%。1这轮下跌导致公司A股市值蒸发逾800亿元，港股市值三天内蒸发超2000亿元。1

股价暴跌的直接触发因素是韩国监管部门的突击搜查。1韩国首尔中央地方检察厅以涉嫌违反《公平交易法》为由，突击搜查了澜起科技、瑞萨电子和Rambus三家公司的韩国办公室，调查涉嫌串通半导体零部件价格。1作为全球芯片市场的主要参与者，澜起科技全球市占率36.8%排名第一，与日本瑞萨电子、美国Rambus三家合计占全球93.4%的市场份额。1公司71.5%的营收来自境外市场，主要客户包括三星电子、SK海力士等。1

与此同时，澜起科技发布了上半年业绩利好。1上半年营收达33.35亿元，同比增长26.6%，归母净利润预增63.9%至81.2%，达到19亿至21亿元。1董事长杨崇和还提议以3至6亿元自有资金回购A股股份。1然而这些积极信号未能抵消反垄断调查带来的市场恐慌。

Luokesai Technology experienced a severe market downturn over three consecutive trading days, with its stock price plummeting over 30% between July 15 and 17 1. The A-share market capitalization evaporated by more than 800 million yuan, while Hong Kong-listed shares lost over 2,000 billion yuan in value across the same period 1. The sharp decline was triggered by South Korea's Seoul Central District Prosecutors' Office conducting surprise raids on the Korean offices of Luokesai Technology, Japan's Renesas Electronics, and the United States-based Rambus, all suspected of violating the Fair Trade Act through alleged collusion in semiconductor component pricing 1.

The stock selloff stood in stark contrast to the company's simultaneous release of positive first-half results. Luokesai reported revenue of 33.35 billion yuan, representing 26.6% year-over-year growth, with net profit attributable to shareholders projected between 19 billion and 21 billion yuan, a 63.9% to 81.2% increase compared to the same period last year 1. The company also announced that its chairman, Yang Chonghe, proposed repurchasing between 300 million and 600 million yuan worth of A-share stock using company funds 1.

Luokesai holds the largest global market share in its sector at 36.8%, with Renesas and Rambus collectively commanding significant portions; the three companies together account for 93.4% of the global market 1. The company derives 71.5% of its revenue from international markets, serving major clients including Samsung Electronics and SK Hynix 1.
