## At a glance

- Seoul's Kospi Index dropped 5% as Samsung's shares tumbled 7%.
- Samsung reported a 1,800% surge in second-quarter operating profit.
- Mixed market reactions across Asia with gains in some regions and losses in others.

Seoul once again led losses on a mixed day in Asian stocks as chip giant Samsung tumbled despite an eye-watering rise in profit, stoking fears that the record-breaking, AI-fuelled rally may have reached the end of the road. Samsung's shares tumbled around seven percent in early trade, dragging the Kospi index down five percent and deepening a rout that has hammered the market for the past two weeks.

## Samsung's Impressive Profit Surge

Samsung announced an expected more than 1,800 percent jump in second-quarter operating profit, attributing the surge to sustained AI-driven demand for memory chips. Despite this impressive financial performance, investor sentiment remained cautious.

## Market Reactions and Investor Sentiment

The Kospi had more than doubled this year to a record high in June, but has shed around 20 percent since then. Analysts suggest that the market is now 'priced for perfection,' meaning that even exceptional results may not satisfy investors who are increasingly focused on the longer-term trajectory of the memory cycle.

## Global Market Movements

There were also losses in Tokyo, Shanghai, and Wellington. However, there were gains in Hong Kong, Singapore, Taipei, Manila, and Jakarta. Sydney saw minimal movement. Oil prices edged up following an incident involving an oil tanker near the Strait of Hormuz.

## Why This Matters

The mixed performance in Asian markets underscores the volatile nature of tech investments, particularly in the context of AI. For Bangladesh, which is increasingly integrating technology into its economic strategies, understanding these market dynamics is crucial. The performance of global tech giants like Samsung can influence investor confidence and market trends, which in turn can impact local tech industries and investment flows.
