周一(yi)大(da)盤再度下挫，最(zui)終滬(hu)深300指數下跌(die)0.93%。期指走勢弱(ruo)于現貨指數，其(qi)中(zhong)主力合約(yue)下跌(die)1.63%，由(you)貼水轉為升(sheng)水24.02點，持(chi)倉(cang)(cang)量減(jian)少(shao)6907手(shou)(shou)至(zhi)(zhi)81457手(shou)(shou)。從(cong)主力席位持(chi)倉(cang)(cang)變(bian)化情況看(kan)，多頭前20合計減(jian)倉(cang)(cang)2195手(shou)(shou)，空(kong)頭前20合計減(jian)倉(cang)(cang)1513手(shou)(shou)，主力凈空(kong)持(chi)倉(cang)(cang)減(jian)少(shao)530手(shou)(shou)至(zhi)(zhi)5960手(shou)(shou)。具體席位上，中(zhong)信期貨加(jia)(jia)倉(cang)(cang)1573手(shou)(shou)多單(dan)并減(jian)倉(cang)(cang)11手(shou)(shou)空(kong)單(dan)，其(qi)凈空(kong)持(chi)倉(cang)(cang)減(jian)少(shao)1584手(shou)(shou)至(zhi)(zhi)2807手(shou)(shou)；國泰(tai)君安減(jian)倉(cang)(cang)139手(shou)(shou)多單(dan)并加(jia)(jia)倉(cang)(cang)414手(shou)(shou)空(kong)單(dan)，其(qi)凈空(kong)持(chi)倉(cang)(cang)增(zeng)加(jia)(jia)553手(shou)(shou)至(zhi)(zhi)4671手(shou)(shou)。綜(zong)合來(lai)看(kan)，在經過(guo)連續兩日超過(guo)200點的(de)大(da)幅震蕩后，空(kong)軍(jun)陣營部分席位在提防弱(ruo)反(fan)彈。但正(zheng)如本欄近期持(chi)續報道的(de)一(yi)樣，在幾大(da)壓力之下，即使有弱(ruo)反(fan)彈，空(kong)頭主力仍有較大(da)的(de)主動(dong)(dong)權，所以仍需留(liu)意空(kong)頭主力的(de)動(dong)(dong)向(xiang)。
