ASX Week 12 market movers reveal significant volatility across major stocks.

ASX Week 12 market movers reveal significant volatility across major stocks. Northern Star Resources experienced a severe 30.82% decline, dropping from above $31 to $18.50 per share due to operational challenges and missed production guidance. The gold producer now faces investor scrutiny as analysts debate whether current levels represent a buying opportunity or signal deeper concerns. Immutep similarly captured attention after a dramatic 90% market cap collapse following the cancellation of its lung cancer therapy trials, wiping over $500 million in value. Both stocks dominate watchlists as traders assess whether recent selloffs present genuine value or warrant continued caution during this volatile trading period.
