    影響認股證價格因素
V. 何時應選擇牛熊證或認股證?

投資者可跟據大市的波動情況選擇合適的牛熊證或認股證產品。當恒指或正股較波動時,投資者可選取認股證,因其輪價會受相關資產的引伸波幅上升帶動。相反,當恒指或正股價格較平穩時,投資者可選取牛熊證,因其絕少受引伸波幅影響,亦可避免相關資產價格大幅波動,令該牛熊證在到期前觸及收回價而被強制收回,停止買賣。

輪證教學追蹤


收市競價對輪證影響?
收市競價市段在7月25日實施,雖然並不適用於認股證及牛熊證產品,不過亦會影響認股證的收市價。由於認股證及牛熊證在下午4時收市,但股份收市競價後,4時10分才會收市。可是認股證的收市價參考了港股及相關資產價格在4時收市的價格,而非在競價時段後的正式收市價。以騰訊(00700)為例,若其4時正的收市價是184.8元,而某認股證的價格是0.345元,但到收市競價後,競價盤令騰訊最終收於184.4元。惟認股證已經收市,輪價仍會收於0.345元,未能反映正股收市價較4時正價格下跌了0.4元。

直至下一個交易日開市,騰訊開市報184.6元,較前競價時段後的正式收市價升0.2元,報價機亦顯示正股價上升了。但該騰訊窩輪收市價是反映騰訊4時正的價格,所以如果現價184.6元,事實上較4時正的收市價跌0.2元。投資者可能會混淆,明明報價機上反映騰訊升了,但窩輪的價格卻下跌,誤以為輪商開價不合理。

牛熊證方面,亦有機會在競價時段才升或跌穿收回價而被收回。假設某恒指牛證收回價在21100點水平,而恒指在4時正的收市價是21230點。不過在競價時段後,恒指最終收市於20980點水平,跌穿收回價而被收回。投資者要做足功課,如果不是太貼市,盡量不要選擇太貼價的產品,減低收回風險。若見勢色不對,趕緊在交易時段立即換馬或沽貨。

至於認股證及牛熊證的到期結算價,亦會使用競價時段後的正式收市價。同時若該收市價,等同兩個交易時段內的最高位或最低位,亦會以該收市價結算。

仙輪抵買嗎?
不少投資者喜歡選擇仙輪,因其入場成本較低。不過面值便宜,並不等於抵買。此類的認股證一般屬價外而年期較短,時間值損耗較快。若引伸波幅回落,輪證價格會再被壓低,受影響較大。
