“全球藍屏事件”+政策利好,易方達基金信息安全ETF、嘉實基金信息安全ETF表現活躍
今日A股繼續維持震盪下跌的態勢,三大指數全線飄綠,板塊繼續上演結構性行情,風電設備、軟件開發和華為鯤鵬等板塊升幅居前。
ETF方面,計算機ETF、軟件ETF和信息安全ETF升幅居前,易方達基金信息安全ETF和嘉實基金信息安全ETF。截至收盤,易方達基金信息安全ETF、計算機ETF南方、華夏基金信創ETF、嘉實基金信息安全ETF分別升2.43%、2.09%、2.08%和1.77%。

今日A股的網絡安全概念逆市上升,一方面是上週微軟Windows“藍屏”故障引發全球IT系統崩潰,市場再次關注網絡安全話題。
消息面上,7月19日,全球網絡安全軟件巨頭CrowdStrike發佈了一個存在缺陷的更新,導致微軟Windows“藍屏”故障,引發全球IT系統崩潰,截止週日晚間,約有超過1500架次美國境內、飛往以及飛離美國的航班被取消。
另一方面,7月21日,《中共中央關於進一步全面深化改革推進中國式現代化的決定》發佈。政策在“推進國家安全體系和能力現代化”章節中提出:國家安全是中國式現代化行穩致遠的重要基礎。必須全面貫徹總體國家安全觀,完善維護國家安全體制機制,實現高質量發展和高水平安全良性互動,切實保障國家長治久安。健全國家安全體系方面,構建聯動高效的國家安全防護體系,推進國家安全科技賦能。在完善公共安全治理機制方面,加強網絡安全體制建設,建立人工智能安全監管制度。
華泰證券認為,相較11年前,本次會議推進國家安全體系和能力現代化更加立體全面,《決定》提及生物安全,網絡安全,人工智能安全監管制度等新機制改革,重點關注涉外國家安全機制。
目前A股有兩隻信息安全ETF,分別是易方達基金信息安全ETF和嘉實基金信息安全ETF,跟蹤的指數都是信息安全,最新規模分別為0.18億元和0.72億元。
中證信息安全主題指數選取涉及信息安全技術、信息安全產品以及信息安全服務等業務的上市公司證券作為指數樣本,以反映信息安全領域相關上市公司證券的整體表現。
信息安全指數的編織方法是對樣本空間內證券按照過去一年的日均成交金額由高到低排名,剔除排名後 20%的證券,再從剩餘的證券裏,選取涉及信息安全技術、信息安全產品以及信息安全服務等業務的上市公司證券納入信息安全主題,最後將挑選出的成份股按照過去一年日均總市值由高到低排名,選取排名前100的證券作為指數樣本。
該指數的前十大權重股分別是,中科曙光、浪潮信息、紫光股份、紫光國微、大華股份、海康威視、寶信軟件、三六零、用友網絡和匯頂科技,合計權重為46.2%。
