小米汽車板塊升幅居前,津榮天宇20CM升停,中捷精工升超16%,創新新材、凱眾股份升停,航天智造、四維圖新升超6%。

消息面上,小米SU7在全國29個城市的60家門店正式開啟靜態展示,門店預約火爆,3月28日晚7點將召開小米汽車上市發佈會。
百度概念午後異動,算力方向領升,潤建股份升停後回落,奧飛數據、依米康升超5%。

消息面上,有媒體稱,百度將為蘋果今年發佈的iPhone16、Mac系統和ios18提供AI功能。蘋果曾與阿里以及另外一家國產大模型公司進行過洽談,最後確定由百度提供這項服務。蘋果預計採取API接口的方式計費。蘋果將國行iPhone等設備採用國產大模型AI功能主要出於合規需求,該公司短期內還無法解決合規問題,但國外版iPhone等設備AI功能均來自蘋果自己的大模型。

展望未來,民生證券認為,實物資產的邏輯拼圖正在逐步清晰:供給約束+需求結構變化下的消耗比例增加+債務壓力下的貨幣價值下降,而掛靠實物生產的上市公司的產能價值重估還遠遠沒有到位,其市值佔比大幅落後於其淨利潤的佔比。推薦:1)掛靠實物屬性的資源品鏈依舊是我們的首要推薦:銅、煤炭、油、資源運輸(油運、幹散等)、貴金屬和鋁。2)圍繞滬深300,在內外需預期同時改善之下,部分傳統制造類龍頭公司開始出現機會(造船、鋼鐵、家電、造紙、重卡等領域);3)看好萬得克強指數相關+低估值國企(銀行、水電、公路、鐵路、燃氣等)。
