China's stock market experienced a significant rebound on Tuesday, driven by gains in the technology sector. The Shanghai Composite index rose 0.3% to 3,822.28 points, while the blue-chip CSI 300 index climbed 1.3%. The ChiNext Price Index and the STAR 50 Index also saw significant gains, rising 5.7% and 4.1% respectively.

The rebound was led by AI and chip shares, which have been under pressure in recent weeks. However, analysts at JP Morgan expect AI to regain market leadership in August, citing a healthy rotation in the market. This rotation may ultimately create a more attractive entry point for investors.

DeepSeek's AI model has been recognized as the least expensive to run on benchmark tests among well-known models globally, according to research firm Artificial Analysis. This achievement may contribute to the renewed confidence in domestic tech developments and the global rally.

The healthcare sector also gained 2.6% on Tuesday, with WuXi AppTec surging by 10%.
