這個模型在去年九十月那輪使用成功,幾個短期波動全捉住,把空倉越養越大。如果後麵我推算靠譜,這個模型有它再次發威的時候。原貼可以去博客聯接,或者搜尋這裏的帖子(那個彩圖好看些)。模型是我手動總結了十一個回調案例,從統計上看出幾天內的一個小小的、但是很確定的分布。這個知識就是金錢。

本輪下跌第一日是上上周四,1%下跌起始。到上周四為第六交易日。我的主要空單在上周三卡窩,因為空方要躲開 第六日的上漲傾向。請看如下11個案例分析。第六交易日平均值略漲,11個樣本隻有一個大跌,一個中跌。相反,有兩個大漲,四個中漲。經曆前五天的艱難 後,這天好比探戈,回趟一步,給沒有清倉的多頭一個機會。這點從表格的下部能更好顯示。頭5天累計跌幅(3.31%)和頭6天比沒有擴大(3.09%)。 從空頭的角度,這好比跑障礙賽,要躲避開這個反彈。首先這天要是漲1%,損失不小。其次,這天反彈會把VIX降下來,空頭可以廉價重新建倉。最不明智的做 法就是在第四或第五天殺跌追著建空倉,這樣做一旦趕上第六日前後的反彈,空方心情大壞,匆忙止損,一步錯,步步錯。這天的反彈是否要搶做多呢?那就仁者見 仁了。我認為兩個方向都做,很容易把自己搞暈,老空頭盼來黎明,不小心成了新多頭。
下麵看第六天以後。在表格最下方,比較了第五到第九的相對漲跌分布。兩個up不一定漲,隻是相對良性的日子。兩個良性日子的平均是6.82和5.91,兩 個惡性分布是第7.45日。這個相差一天的分布意味著從第五到第九交易日,後半程(即第七日以後)盤勢轉弱。從平均值看,第九交易日是確定第一日後跌幅最 大的一個。
該模型使用的難度在於確定第一日,和識別經典下調。今年四月和八月的不是,這個模型不管用。本次上周四為第六日,出長下影探1926底,周五為第七日,三 大指數1%上漲。這進一步確證這回有很大把握是經典回調,即第九日下周二(或周三,因為大漲出在第七日)附近盤勢再次轉弱。因此我聲稱留給反彈的時間不 多,下周或許指望上衝一下填補1973的月線缺口。此後的走勢,至少是在1973到1926期間盤整。
這不是大數據。十二少的小數據,有理有據,鄙視瞎喊。沒有實料每天上三五十個帖子灌水的,適可而止。
