盤面上,傳中國鼓勵在全國範圍內使用開源RISC-V芯片,半導體板塊爆發,芯原股份、安路科技雙雙20%升停,AI芯片、汽車芯片及儲存芯片等跟升;傳聞稱特朗普即將宣佈“退出北約”,軍工股全天強勢,晟楠科技30cm升停;機器人應用等新質生產力相關議題或為今年政府工作報吿的重點之一,機器人板塊活躍,捷昌驅動等多股升停;腦機接口、星閃概念及北斗導航等板塊升幅居前。另外,固態電池板塊回撤,三祥新材跌停;人造肉板塊走低,東方集團跌停;免税概念、煤炭行業及鋰礦概念等跌幅居前。

具體來看:

半導體板塊午後發力走高,芯原股份、安路科技20%升停,全志科技、國芯科技升超15%,翱捷科技升約14%,北京君正、燦芯股份、華大九天等升超10%,紫光國微升停。

人形機器人概念股多股走強,天正電氣4連板,杭齒前進、兆威機電、萬馬股份、智微智能、上海機電等個股升停。

消息面上,3月3日,深圳市科技創新局印發《深圳市具身智能機器人技術創新與產業發展行動計劃(2025-2027年)》。其中提到,重點支持具身智能機器人核心零部件、AI芯片、仿生靈巧手、基座及垂直領域大模型、本體控制等關鍵核心技術攻關。

汽車產業鏈股跟隨強勢,西菱動力、動力新科、萬安科技、襄陽軸承、浙江黎明、躍嶺股份、南方精工等紛紛升停,

民生證券認為,2025年為智駕全面加速的一年,FSD入華,比亞迪開啟智駕全系標配,以“規模化”與“普惠性”為底層邏輯,有望加速智駕平權,促進智駕功能成為買車重要考慮因素,鮎魚效應或將帶動其他車企追趕,正式開啟中國汽車的智駕平權時代,帶動產業鏈協同發展。

軍工股全天強勢,新興裝備、洪都航空、立航科技、新興裝備、煉石航空、北方長龍等升停,天和防務、航發科技、內蒙一機等個股升幅居前。

消息面上,猶他州共和黨籍聯邦參議員邁克·李等在內的多位政界人士呼籲美國退出北約,稱從歐洲撤出所有美軍,美國將節省數十億美元的納税人資金。值得注意的是,特朗普昨日稱將在美國東部時間星期二晚上宣佈“大事情”。再加上昨日歐洲軍工股集體大升,有市場傳聞稱特朗普即將宣佈的“大事情”便是“退出北約”。

DRG/DIP概念股再迎來反彈,創業慧康升超17%,麥迪科技、衞寧健康、思創醫惠、塞力醫療等個股升幅居前。

光大證券認為,中國AI行業大發展,AI+醫療賽道有望迎來拓寬,AI大模型成本的快速下降與性能的快速提升,也將導致其在醫療領域的進一步落地。

固態電池概念股跌幅居首,龍蟠科技、三祥新材跌停,德爾股份跌近10%,光華科技、紫建電子等跟跌。

大消費表現分化,白酒板塊回調明顯,巖石股份跌超4%,今世緣、酒鬼酒、皇台酒業、老白乾酒等跟跌。

機構認為,白酒行業經歷三個階段。第一階段是總量擴張階段,白酒業績源自於量、價齊升;第二階段是結構性增長階段,個股業績來自於單品均價及結構上行,集中度提升來自於價格端;當下正處於第三階段,白酒行業在經過庫存週期後快消品屬性強化,奢侈品屬性弱化,行業邏輯由價的集中到量的集中,頭部企業仍能通過集中度提升實現較高的業績確定性。

展望後市,東莞證券指出,近期美國關税貿易政策的不確定性,可能會對全球市場造成一定衝擊,同時地緣政治緊張或推升資金避險需求。從國內環境來看,2月PMI錄得50.2%,重新回升至榮枯線上方,顯示出我國經濟景氣水平總體有所回升。往後看,1、2月經濟數據開始陸續披露,驗證本輪逆週期發力成色,A股短期或延續結構性分化行情,但中期趨勢仍具備向上動能。此外,兩會的政策預期或能給予A股較好的支撐,像支持民營經濟、民生消費和科技創新的政策,有望得到進一步部署,市場或呈現震盪偏強格局。
