RAM is trading at $13.88 (-4.04%) as higher Treasury yields weigh on high-valuation semiconductor and AI stocks. - The 10-year yield is near 5.1%, while Micron, SanDisk, Western Digital and Seagate are also falling in premarket trading. - Investors are taking profits after RAM’s roughly 33% advance across five prior sessions; elevated valuations and potentially slower memory-demand growth add pressure. - RAM’s 2x daily leverage amplifies the underlying DRAM-sector decline, extending the September 23 decline.
