Biren Technology's stock plummeted 5.07% during intraday trading on Tuesday, diverging sharply from the broader market trend.

The decline was primarily driven by profit-taking pressure following the stock's formal inclusion in the Stock Connect eligible securities list, which the market treated as a classic "sell-the-news" event. Additionally, sentiment was weighed down by the company's recent application to convert approximately 868 million unlisted domestic shares into H-shares, significantly increasing potential share supply and creating concerns about dilution.

Notably, the sell-off occurred despite a rally in the broader semiconductor sector, indicating that the pressure on Biren Technology was driven by these specific company-related factors rather than sector-wide weakness.
