Rally enters a new phase, shifting from market-wide to stock-specific
The internal structure of the current rally shifted noticeably last week: Samsung rose nearly 17%, SK Hynix nearly 14%, and Advantest nearly 17%, making memory and testing equipment the new leading sectors. In contrast, Broadcom, which had been leading, fell more than 8%, while Amazon, Apple, and Alphabet also saw declines. Funds have not left the market but have shifted within the AI supply chain from fully priced platform layers to profit-revised, undervalued memory and equipment layers. It is also important to note changes in positions: hedge fund net leverage has risen from a low point to about 80%, approaching historical warning levels. Combined with the密集的财报考验后的估值修复值得部署关注。
