No you don't. Frequency of hedging is a very tricky question - would you hedge your book "continually" if you are short gamma? if you are long gamma? long gamma in a trending market?Quote from DerivativesG:
You don't delta hedge frequently, you continually adjust your
delta hedge real time during the trading day.
However, experience of 15 years at a major investment bank and being a vol arb portfolio manager in a billion+ hedge fund does make me an expert. Now, I am not a equity options maven, but I have a guy sitting next to me who is an ex-MM in single name options and I just asked him:Quote from DerivativesG:
Good for you. Obviously your one year of "market making"
does not make you an expert in all kinds of options market
making.
sle: ***, do you know what "Income Trades" are?
***: well, I can guess what it is but I've never heard it before.
The point is that you (among other people) tend to mislead novices. My point was not to "know your greeks" but rather to "analyze your trades from the vol perspective".Quote from DerivativesG:
Of course you are either long
or short gamma and you follow the other greeks such as
vega, omega, theta etc. and that decision is so obvious, but
why are you telling us stuff that is options 101? What's your point?
