公開市場買進(P)是內部人自掏腰包,通常比賣出更有資訊含量 —— 賣出的理由很多(繳稅、分散、買房),買進的理由只有一個。

10b5-1 是事先排定的交易計畫,執行時點不反映當下看法。獲配股票(A)、繳稅扣股(F)、選擇權執行(M)是薪酬流程,不是意見。

FINRA 每月兩次結算的空單餘額佔流通股數的比例,近 13 個月。滑到柱子看股數與回補天數。

最新一期

空單股數12.7M
與上期比-5.1%
佔流通股數11.43%
日均成交量5.4M
回補天數2.4

空單佔比 10% 以上算高、20% 以上算很高(這是通行的說法,不是本站的判斷)。回補天數 = 空單 ÷ 日均量,天數愈長,空方要出場時愈容易推升股價。

放空餘額是「有人借股票賣掉還沒還」的存量,不代表看空的人正在加碼;避險基金做多空配對時也會產生空單。
