在高盛的報告看到一段話:the russell 2000 has outperformed the SPX for 11 consecutive sessions (first time since 2008) … despite the rally in spot, there has been almost zero investor demand … small caps are one of the few where spot returns and call vol correlations are quite positive (classic “chase asset” behavior) – call options have “yet” to go bid this time
解釋:
羅素2000連續11個交易日跑贏標普500,是2008年以來首次出現的情況,表示市場風格正在劇烈切換。儘管小型股的現貨價格飆升,但數據顯示投資人的買入量並不高,這可能表示主力資金還沒進場,更可能是因為空頭回補或是市場流動性低導致的價格拉升,投資人目前還在觀望,並沒有真正上車。
大多數資產在股價漲的時候,波動率會下降,然小型股是少數的「追逐型資產(chase asset)」,當小型股大漲時,投資人會因為害怕錯過大舉買入買權來槓桿跟進,隱含波動率反而更高。今年以來波動率並未提高,可能顯示行情還沒到頂。
