I have weekly volatilities over 370 weeks, I like to convert this into an annulized volatility..How does this work?
ReplyDeleteThere are 52 weeks in a year, so divide the weekly volatility by √52.
ReplyDeletemultiply it by root 52, not divide
ReplyDeleteYes, anonymous, you're correct. From weekly to annual you need to multiply by √52
ReplyDeleteI have daily volatility. How can I convert it to monthly volatility? How about multiply it by root 30? Thank you for your help.
ReplyDeleteBetter multiply by sqrt(21) - approximate number of trading days in a month.
ReplyDeleteThis is always a debatable issue
Deletethat how much Days should use to
convert Daily volatility to other specifice time period as
(one week or month , year etc
Because as India's Top exchange
* NSE * Uses √365 to transform
Daily Volty to annulized Volty
But in US they use √252
So my opinion is to follow the exchange in which one is trading
Plz share your opinion
I have two questions.
ReplyDeleteHow can I convert monthly volatility to quarterly volatility?
How can I convert daily volatility to quarterly volatility?
