Argenx Shares Drop 3.46% on $420M Volume Surge Ranks 238th in Daily Trading Activity

On August 11, 2025, argenx (NASDAQ: ARGX) reported a 3.46% decline in its share price, with a trading volume of $420 million, reflecting a 125.7% surge from the previous day. The stock ranked 238th in trading activity among the day’s market participants.

The FDA’s June 30 alert regarding argenx’s Vyvgart Hytrulo drug raised concerns about severe risks of worsening chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). This prompted Pomerantz LLP to investigate potential securities fraud or unlawful business practices by the company and its officers. The regulatory scrutiny has intensified investor uncertainty, contributing to the recent volatility in argenx’s stock performance.

A backtested trading strategy of purchasing the top 500 stocks by daily trading volume and holding them for one day generated a 166.71% return from 2022 to the present, outperforming the 29.18% benchmark by 137.53 percentage points. This highlights the significance of liquidity concentration in short-term momentum-driven returns, particularly in markets with high volatility.
