Quote from kalashnicac:
Ok got your point.
I am aware dynamic hedging comes at a cost, sometimes to the extent that it wipes out the whole profit potential of an option trade. But "partial" delta hedging can reduce risk. You could for instance leave the position breathe a bit instead of adjusting delta every second. Just making sure the position doesn't get too directional (one could try to keep delta under a particular number, say 30) seems a reasonable way to avoid the big losses.
With "loose" (as opposed to tight) delta hedging, you limit your risk and who knows you can even make money hedging.
You are ignoring price gaps. When volty is high, its' telling you there is a substantial risk for a price gap which CANNOT be hedged. Letting a position breathe is not the answer either. This is in response to you thinking there is EDGE in selling high volty. In order to capture that premo, you have to lock in deltas otherwise you are not making a volty bet, but rather a delta bet.
I guess what I am trying to say, is that it's incredibly difficult. Price gaps blow guys out and sometimes the entire firm they are with. Do a little bit of research and you will find that even such masters as Charles Cottle not only blew himself out several times, but actually almost blew out not only his firm but almost the entire exchange. He was letting his position breathe. LOL.
