〔Day Digest〕AI Hardware Slips 2-7% as Funds Pivot to Apps, TSMC Flags Agent CPU Shortage, DeepSeek Outage Hits 4h52m with 7-Day API Refund - Rotation Trade Tests Capex Story

0. Daily Arc

Capital rotated out of AI hardware into applications in the Asian session - Eoptolink (300502.SZ) -7.49%, Innolight (300308.SZ) -5.19%, Tianfu Communication (300394.SZ) -2.48%, while Ciwen Media (002343.SZ) hit a fifth consecutive daily limit-up on the AI short-drama concept ^[1]. The rotation sits awkwardly against structural-bullish signals: TSMC says AI-agent CPU demand already outruns supply ^[2], Goldman projects Alphabet 2027 capex of US$349.896bn (+72.2% y/y) ^[3], and Chinese AIoT chipmakers Rockchip and Longsys posted 68-73% ^[4] and 1864-1990% ^[5] Q1-3 profit growth respectively. A 4h52m DeepSeek outage ^[6] with a 7-day API credit refund ^[7] added a sentiment drag. Net: a rotation trade testing a capex-led structural story.

1. Hardware-to-Application Rotation

• **[NEW] Longsys (江波龙):** Q1-3 attributable profit guidance RMB 14.0bn-14.9bn, +1864.55-1990.84% y/y, as the memory industry shifts from a consumer-price cycle to an AI-driven tech cycle and large/high-end/global customer share rises ^[5].
• **[NEW] IMF:** the KRW/JPY divergence is more likely driven by the AI boom's effect on current and capital accounts than by the Japan-Korea rate spread, which has not widened materially; KRW appreciated 11% versus JPY from July 1 to Sept 3 ^[10].
• **[NEW] Compute buildout shift:** Wanxin exhibition expert (Guangming Laboratory) said compute focus over the next five years will shift from scale expansion to quality improvement and ecosystem maturity ^[11].
