消息面上,OpenAI發佈首個文生視頻模型Sora,可以根據用户的文本提示快速製作長達一分鐘的逼真視頻。平安證券指出,當前,全球範圍內大模型領域的競爭依然白熱化,這將持續拔升大模型的整體能力水平。大模型需要大算力,大模型算法的迭代升級將為全球和中國AI算力市場的增長提供強勁動力。在美國對華半導體出口管制升級的背景下,我國國產AI芯片產業鏈將加快成熟,相關AI芯片和服務器廠商將深度受益。另外,在應用端,我國國產大模型能力持續升級,AIGC產業未來發展前景廣闊。可關注算力、算法、應用場景、網絡安全方向。
教育板塊升幅居前,開元教育、全通教育20CM升停,凱文教育、昂立教育、傳智教育升停。消息面上,日前教育部發布《校外培訓管理條例(徵求意見稿)》公開徵求意見的公吿,擬首次將校外培訓管理上升為行政法規。

展望後市,招商策略研報認為,春節假期期間全球股市升跌不一,港股延續年前反彈趨勢喜迎開門紅,市場對美聯儲降息預期繼續降温。相比之下,國內1月社融實現開門紅,春節假期出行熱度提升,消費持續復甦。往後看,隨着流動性衝擊逐漸化解,市場有望逐漸築底回升,A股走成類似2016年的概率進一步加大。行業層面,電子、計算機、機械、醫藥等涉及人工智能等新技術趨勢和新質生產力方向,建材、輕工等受益於三大工程和地產穩增長政策的方向為未來行業佈局的重要線索。
