給點對vix的個人理解,
希望原po能更加了解vix。
背景知識:
1BS模型(選擇權訂價模型)
2位移速度加速度定義(國中理化)
若不精確的說明定義,
vix是一個股價的二次微分方程。
不懂沒關係,(其實我也在摸索中)
但至少有一個重要觀念,
vix和股價不是線性關係。
白話來說,
股價漲跌和vix關係不是一般人直覺可判斷。
為了能更直覺了解vix,
我常用簡單的物理學類比
(不精確,類比有誤請指正)
如果股價漲幅是位移,
則漲幅快慢是速度,
期貨可類比成速度,
vix就可以類比成加速度。
從簡單物理學可知,
加速度和速度不一定同向,
更別提和位移同向。
就是vix不和股價漲幅有線性關係。
何時加速度(vix)會有最大值?
就是速度轉向時。
白話來說,就是股價轉折點。
這類比剛好說明一般人常有的迷思,
股價跌深時,買vix是不合理。
(類比可知非線性,等同誤判不理性買法)
建議基於線性關係為買賣依據,
反而要買賣期貨。
同理可證,
為何技術分析不適合vix?
(因為一般技術分析都是建立在線性類比關係上成立的)
為何加碼攤平策略不適合vix?
因為買賣vix,如同買賣轉折點。
加碼攤平策略比較適合趨勢策略。
買賣vix正統玩法,比較符合避險套利策略。
最後,
若要買賣vix,
個人建議要搭配期貨,
進行避險套利策略才是正統玩法。
玩法就是依據資金部位流動性,
買賣預期的漲幅(期貨),
買賣不確定性的漲幅變化(vix)。
一般人單買賣vix的,
我覺得就當買樂透作公益,
國家會感謝你的交易稅。XD
我走來始終如一,小志工下台一鞠躬。
