The week began on a weak footing: Monday (14 Sep) opened at $54.63, touched an intraday low of $54.285, and settled at $54.80. Tuesday and Wednesday stayed range-bound between roughly $54.4 and $56.6. Buying returned on Thursday (17 Sep), with a gap higher to $57.78, and Friday (18 Sep) saw a stronger advance to a session high of $59.696 before closing near the week’s top. Weekly amplitude reached 9.9%. Average daily volume of about 28.2m shares was 46.07% below the 60-day median, pointing to thinner participation. ## Sector News The semiconductor complex revolved around the pace of AI development this week. On Monday, European calls to slow AI development hit pre-market sentiment, with Micron down more than 5% at one point and the Philadelphia Semiconductor Index falling nearly 6%. DRAM itself dropped over 6% intraday. The pressure extended into Tuesday, when SOXL fell nearly 15% and EUV nearly 7%, while cybersecurity and cloud names bucked the trend. Sentiment steadied midweek: SK hynix and Intel were reported to be exploring memory production in Ohio, and BIMB argued the AI infrastructure boom is far from over and is in a capacity-expansion phase. Friday brought a late surge in AI hardware, with the SOX index up 2.8% and Micron up nearly 4%, memory stocks leading the gains. SanDisk added another layer of attention with a $14bn buyback announcement and its upcoming entry into the S&P 100. ## The Week Ahead The macro calendar is light, but several US data points are worth tracking. Tuesday (22 Sep) brings the Richmond Fed composite index, with a prior reading of 4. Wednesday (23 Sep) includes EIA weekly crude and Cushing inventory data. Thursday (24 Sep) is the busiest, with initial jobless claims, the current account balance, new home sales, and EIA natural gas storage all due. For memory-related assets, the more direct focus will be fund flows around SanDisk’s entry into the S&P 100 on Monday, as well as any follow-through on the AI infrastructure expansion narrative. The sector has already shown sharp intraday swings this week, so any macro or equity-style shift could keep volatility elevated. ## In Short DRAM ended the week modestly higher, but the path was uneven: early pressure from AI-slowdown calls gave way to a late-week rally led by memory stocks. The sector sits between a long-term AI infrastructure build-out story and shorter-term debate over the pace of that build-out. SanDisk’s index inclusion and buyback added another catalyst. On valuation, PE and PB readings are not available for this fund; the latest session turnover rate was 7.03%. A single-day capital snapshot showed large, medium, and small-lot flows all tilted net seller, though this is one day rather than a weekly trend. What matters next is whether flows around SanDisk’s S&P 100 entry persist, whether AI-related news sustains Friday’s firmer tone, and how next week’s macro data shapes risk appetite across tech. *This article is generated by LongbridgeAI from market data, for information only and not investment advice.* ### Related Stocks - [DRAM.US](https://longbridge.com/en/quote/DRAM.US.md) ## Related News & Research - [Omdia: Global Semiconductor Revenue Exceeds USD425 Billion in 2Q, Hitting Another Record High](https://longbridge.com/en/news/299728345.md) - [SanDisk Stock Hits All-Time High As AI Memory Trade Regains Momentum](https://longbridge.com/en/news/282212259.md) - [Sandisk Stock Price Forecast — Top Rosenblatt Analyst Sees 36% Upside as 'AI Creates New Opportunity for SNDK'](https://longbridge.com/en/news/299751475.md) - [Micron's (MU) AI Boom Could Outlast the Memory Cycle](https://longbridge.com/en/news/299769666.md) - [CoreWeave Stock: Five-Star Analyst Sees 76% Upside amid AI Cloud Rivalry](https://longbridge.com/en/news/299786745.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
