The memory chip sector is experiencing a significant pre-market rally, continuing a strong upward trend driven by an AI-fueled 'supercycle'. Commentary from industry leaders highlights 'explosive' demand growth for memory chips used in AI infrastructure, with supply struggling to keep pace.

Positive financial outlooks and strong investor inflows into sector-specific ETFs are further fueling the bullish sentiment.
