On the morning of August 21, the A50 index soared, propelling a broad-based rebound across major A-share indices.

Simultaneously, South Korea's stock index reversed its earlier decline to post gains, while Japan's stock market decline significantly narrowed. Three pivotal positive developments have emerged in global markets:

First, U.S. bond yields, a long-standing concern for investors, dropped across the board following the opening of Asia-Pacific markets. Shifts in expectations within the U.S. Treasury bond market have fueled a weakening trend in the U.S. dollar, which is generally favorable for equity valuations as it makes investments in equities relatively more attractive compared to dollar-denominated assets.

Second, the Korea Exchange implemented its Sidecar mechanism, temporarily halting algorithmic selling on the KOSDAQ market. This move aims to stabilize market volatility and prevent excessive downward pressure, thereby fostering a more orderly trading environment.

Traditionally plagued by boom-and-bust cycles, the memory sector now appears poised for a more sustainable growth trajectory, thanks to the transformative impact of AI on demand patterns and technological advancements.
