On the news front, influenced by concerns over NVIDIA's significant AI supply agreements and intensified market competition, the Japanese and South Korean stock markets opened lower and continued to decline. As of July 28, the Nikkei index's intraday decline expanded by over 4%, reaching its lowest level since May 22, with Japan's leading storage company Kioxia closing down over 18%. Nomura stated that following reports of significant investment transactions involving NVIDIA, its credit risk has increased, which investors view as a bearish signal. Additionally, China's advancements in semiconductor manufacturing equipment pose a threat to Japanese suppliers, who have long held a competitive advantage in this field. Goldman Sachs' Japan equity strategy analyst Bruce Kirk pointed out that the current macro environment facing the yen is fundamentally different from two years ago, with the conditions triggering rapid yen appreciation significantly weakened; however, the degree of crowding in stock positions, whether in terms of net foreign purchases, hedge fund allocations, or retail financing balances, has exceeded or significantly surpassed levels seen in July 2024. The probability of a currency flash crash has decreased, but should unexpected shocks occur in the AI narrative or geopolitical landscape, the vulnerability of the Japanese stock market is even higher than it was two years ago ### Related Stocks - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [NVD.US](https://longbridge.com/en/quote/NVD.US.md) - [NVDY.US](https://longbridge.com/en/quote/NVDY.US.md) - [NVDQ.US](https://longbridge.com/en/quote/NVDQ.US.md) - [NVDX.US](https://longbridge.com/en/quote/NVDX.US.md) - [NVDU.US](https://longbridge.com/en/quote/NVDU.US.md) - [NVDS.US](https://longbridge.com/en/quote/NVDS.US.md) - [NVDD.US](https://longbridge.com/en/quote/NVDD.US.md) - [NVDL.US](https://longbridge.com/en/quote/NVDL.US.md) - [NVDB.US](https://longbridge.com/en/quote/NVDB.US.md) - [NVDG.US](https://longbridge.com/en/quote/NVDG.US.md) - [NVDO.US](https://longbridge.com/en/quote/NVDO.US.md) - [NVDW.US](https://longbridge.com/en/quote/NVDW.US.md) - [NVYY.US](https://longbridge.com/en/quote/NVYY.US.md) - [NYYY.US](https://longbridge.com/en/quote/NYYY.US.md) - [DIPS.US](https://longbridge.com/en/quote/DIPS.US.md) - [MAGX.US](https://longbridge.com/en/quote/MAGX.US.md) - [SMH.US](https://longbridge.com/en/quote/SMH.US.md) - [SOXX.US](https://longbridge.com/en/quote/SOXX.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) - [SOXQ.US](https://longbridge.com/en/quote/SOXQ.US.md) - [XSD.US](https://longbridge.com/en/quote/XSD.US.md) - [PSI.US](https://longbridge.com/en/quote/PSI.US.md) - [FTXL.US](https://longbridge.com/en/quote/FTXL.US.md) - [07388.HK](https://longbridge.com/en/quote/07388.HK.md) - [07515.HK](https://longbridge.com/en/quote/07515.HK.md) - [07788.HK](https://longbridge.com/en/quote/07788.HK.md) - [09388.HK](https://longbridge.com/en/quote/09388.HK.md) - [YCS.US](https://longbridge.com/en/quote/YCS.US.md) - [NMR.US](https://longbridge.com/en/quote/NMR.US.md) - [8604.JP](https://longbridge.com/en/quote/8604.JP.md) - [GS.US](https://longbridge.com/en/quote/GS.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) - [W4VR.SG](https://longbridge.com/en/quote/W4VR.SG.md) ## Related News & Research - [Nvidia's Potential $250 Billion OpenAI Financing Deal Is Reviving a 1990s Tech Bubble Habit, Analyst Warns: 'Usually Don't End Well'](https://longbridge.com/en/news/294077412.md) - [Nvidia supplier Wistron launches $700 million Texas factory for AI system production](https://longbridge.com/en/news/293413420.md) - [As Nvidia Discloses a 9.3% Stake in Nebius, Here’s How You Should Play NBIS Stock](https://longbridge.com/en/news/293504980.md) - [Nvidia forms industry alliance for open AI security after Hugging Face hack](https://longbridge.com/en/news/293916175.md) - [Tech coalition warns against sweeping artificial intelligence limits](https://longbridge.com/en/news/293799635.md)
