正如(ru)本欄分享的(de)(de)一樣，多空(kong)(kong)主(zhu)力廝殺激烈，周二大盤早盤一度強力上攻，后快速(su)回落，最后滬深300指數(shu)下跌(die)0.34%，全天振幅(fu)(fu)達1.29%。期(qi)指走勢弱于現貨(huo)(huo)指數(shu)，其(qi)中(zhong)10月合(he)約(yue)下跌(die)0.49%，提水(shui)(shui)幅(fu)(fu)度擴大到(dao)7.96點，持(chi)倉(cang)量繼續(xu)大幅(fu)(fu)減少19160手(shou)(shou)(shou)(shou)至91676手(shou)(shou)(shou)(shou)；即將成為主(zhu)力合(he)約(yue)的(de)(de)11月合(he)約(yue)跌(die)幅(fu)(fu)為0.54%，由小幅(fu)(fu)升水(shui)(shui)變(bian)為貼水(shui)(shui)3.96點，持(chi)倉(cang)量增(zeng)加11997手(shou)(shou)(shou)(shou)至32322手(shou)(shou)(shou)(shou)。從主(zhu)力席位持(chi)倉(cang)變(bian)化情(qing)況(kuang)看，10月合(he)約(yue)上，空(kong)(kong)頭(tou)(tou)主(zhu)力瘋狂減倉(cang)，前20合(he)計減倉(cang)14918手(shou)(shou)(shou)(shou)，遠多于多頭(tou)(tou)前20合(he)計減倉(cang)的(de)(de)7671手(shou)(shou)(shou)(shou)；其(qi)中(zhong)空(kong)(kong)軍司令海(hai)通期(qi)貨(huo)(huo)大肆減倉(cang)空(kong)(kong)單2432手(shou)(shou)(shou)(shou)；主(zhu)力凈空(kong)(kong)持(chi)倉(cang)已快速(su)下降到(dao)9131手(shou)(shou)(shou)(shou)。11月合(he)約(yue)上，空(kong)(kong)頭(tou)(tou)前20合(he)計增(zeng)倉(cang)10452手(shou)(shou)(shou)(shou)，略多于多頭(tou)(tou)前20合(he)計增(zeng)倉(cang)的(de)(de)9410手(shou)(shou)(shou)(shou)，主(zhu)力凈空(kong)(kong)持(chi)倉(cang)小幅(fu)(fu)增(zeng)加到(dao)3299手(shou)(shou)(shou)(shou)。值得注意的(de)(de)是，11月合(he)約(yue)上，廣發(fa)期(qi)貨(huo)(huo)以凈空(kong)(kong)持(chi)倉(cang)超(chao)過(guo)3000手(shou)(shou)(shou)(shou)暫時成為新的(de)(de)空(kong)(kong)軍司令，而傳統空(kong)(kong)軍主(zhu)力中(zhong)信期(qi)貨(huo)(huo)成為做(zuo)多主(zhu)力之一，海(hai)通期(qi)貨(huo)(huo)凈空(kong)(kong)持(chi)倉(cang)才(cai)418手(shou)(shou)(shou)(shou)。期(qi)指主(zhu)力的(de)(de)布局似乎在悄(qiao)悄(qiao)發(fa)生改變(bian)。
