SG Micro Corp's stock plunged 7.00% during intraday trading on Thursday, reflecting significant downward pressure on the semiconductor company's shares.

The sharp decline comes amid broad-based selling pressure across the semiconductor sector, with multiple industry peers also experiencing significant losses. SG Micro's AH-share premium deviation has remained persistently negative, indicating continued valuation pressure on its H-shares relative to their 30-day average.

Adding to the volatility, the stock recorded substantial position transfers totaling HK$1.2 billion, representing 18.97% of shares, with significant movements into and out of major financial institutions. This institutional fund rebalancing activity may be amplifying near-term price fluctuations in the stock.
