Super Micro Semiconductor September 28 Decline Interpretation

Keywords: OpenAI training halt, oil prices rise, bonds up, pullback from highs

1. On September 28, OpenAI suspended training and testing of its most advanced artificial intelligence models, raising concerns about the pace of AI development and slowing chip demand growth. As an AI chip supplier, AMD was affected.

2. On September 28, crude oil prices rose and US Treasury yields increased. US stock index futures and the semiconductor sector declined. Interest rate-sensitive and high-valuation tech stocks came under pressure, with AMD falling in tandem with Intel and Broadcom.

3. On September 28, AMD's share price was previously at a high level and had posted significant year-to-date gains. In addition, after Nvidia announced a $150 billion share buyback and its stock price rose, the positive impact did not spread to its peers. Some investors took profits, further amplifying AMD's short-term correction pressure.
