創業板註冊制下的漲停板別輕易追

創業板註冊制下實行20%漲跌停板,如果漲停,相當於過去的兩個漲停板,投資者如果盲目追漲,一旦遇到打開漲停,可能會受到較大損失。

有一種操作,叫“天地板”;還有一種操作,叫“釣魚線”。這些做法的原理在於莊家利用散户的追漲和抄底心理吸引散户投資者高位接盤,最終實現高位出逃的目的。原本10%的漲停板似乎對於投資者的殺傷力還不算大,但是如果在20%的漲跌停板之下,股票單日振幅就能達到40%,一旦投資者高位追漲,一天浮虧40%並不稀奇,如果考慮到第二天的股價低開,虧損一半也有可能。

在20%的漲停板制度下,一旦股票快要強勢封上漲停,此時原本喜歡追漲停板的投資者一定是很糾結的,要不要追漲停?如果不追,可能會失去連續漲停的機會;如果追,那麼莊家一旦反手出貨,股價是可以下跌40%的。在如此之大的利潤誘惑下,莊家假意推高股價到漲停,甚至短時間封死漲停板也是有利可圖的,投資者一旦高位買入股票,就意味着這一整天都沒辦法止損出局,一旦股價出現從漲停板到跌停板的放量殺跌,投資者除了眼睜睜地看着,沒有任何應對措施,畢竟當下的交易制度是T+1。

科創板雖然也是20%的漲跌停板,但是問題相對不大,因為科創板的門檻比較高,真正的散户投資者並不多。本欄不是説錢多的投資者就不在乎鉅額虧損,而是説在一個缺少散户的市場裏,莊家不太願意採用欺騙的手法去誘導其他投資者追高,因為科創板股票一旦出現非理性的高價,不僅有原本持股的投資者會逢高賣出,同時還有可能遭遇融券資金賣空股票。

但是創業板則不同,創業板裏面有太多的中小投資者,莊家操縱股價的潛在收益太高,而且創業板股票也沒有什麼融券的券源,所以莊家是有動機通過製造漲停的假象來收割韭菜的。在此背景之下,投資者追高漲停的風險就會很大。所以本欄認為,喜歡追漲停的投資者一定要認真研究10%漲停和20%漲停的差異,如果早盤20%漲停追入股票,這一天可能都會提心吊膽。

那麼問題來了,什麼樣的漲停可以追,什麼樣的漲停最好別追?本欄認為,這還得看上市公司的基本面,投資者最好不要在意股價是否漲停,而要重點關注股票的當前股價是否具有投資價值。如果股價明顯已經過高,市盈率水平、市淨率水平都處在同行業的較高水平,那麼投資者對於這樣的股票最好還是多加小心;相反,如果股價仍然處於較低的位置,那麼追第一個漲停板或許風險也可以承受。

當然,20%漲跌停板之後,漲停股票的數量會有所下降,相對應的可轉債過度炒作也會有所收斂,這是一個好事。不過本欄認為,對於20%漲跌幅的板塊,還是應該儘早推出單次T+0的交易制度,給投資者一個止損出局的機會,否則“天地板”的風險確實有些偏大。
