周一大(da)盤繼(ji)續(xu)震蕩上(shang)漲，滬深300指數最后(hou)漲0.59%。不過期(qi)指走勢較弱，其(qi)(qi)中(zhong)主(zhu)(zhu)力合約漲幅僅0.19%，升水幅度大(da)幅收窄至1.64點；持倉(cang)(cang)(cang)量減(jian)(jian)少2242手(shou)至145024手(shou)。從主(zhu)(zhu)力席位持倉(cang)(cang)(cang)變(bian)化(hua)情況看(kan)，多(duo)(duo)空(kong)主(zhu)(zhu)力均在減(jian)(jian)倉(cang)(cang)(cang)，其(qi)(qi)中(zhong)多(duo)(duo)頭(tou)(tou)前(qian)20合計減(jian)(jian)倉(cang)(cang)(cang)1568手(shou)，空(kong)頭(tou)(tou)前(qian)20合計減(jian)(jian)倉(cang)(cang)(cang)1328手(shou)，多(duo)(duo)頭(tou)(tou)主(zhu)(zhu)力減(jian)(jian)倉(cang)(cang)(cang)力度略大(da)于空(kong)頭(tou)(tou)主(zhu)(zhu)力。具體席位上(shang)，空(kong)軍(jun)司令中(zhong)信期(qi)貨是雙向大(da)減(jian)(jian)倉(cang)(cang)(cang)，減(jian)(jian)倉(cang)(cang)(cang)空(kong)單1350手(shou)，同時減(jian)(jian)倉(cang)(cang)(cang)多(duo)(duo)單1635手(shou)，其(qi)(qi)凈空(kong)持倉(cang)(cang)(cang)繼(ji)續(xu)增加到(dao)12336手(shou)；而空(kong)軍(jun)第二大(da)主(zhu)(zhu)力海通期(qi)貨減(jian)(jian)倉(cang)(cang)(cang)多(duo)(duo)單214手(shou)，減(jian)(jian)倉(cang)(cang)(cang)空(kong)單542手(shou)，其(qi)(qi)凈空(kong)持倉(cang)(cang)(cang)下降到(dao)9145手(shou)；這表明空(kong)軍(jun)前(qian)兩(liang)大(da)主(zhu)(zhu)力短線出(chu)現了分歧。綜合來看(kan)，盡管大(da)盤走勢很強，但多(duo)(duo)頭(tou)(tou)主(zhu)(zhu)力并沒有(you)繼(ji)續(xu)擴大(da)戰果(guo)的底氣，而是逢高兌現部分利潤(run)；需(xu)警惕空(kong)頭(tou)(tou)主(zhu)(zhu)力發動突然襲擊。
