hedging can be an art form...some short gama guys trade the stock if they are long gama...gotta have balls and deep pockets for that...i like to use chart...will not buy more stock if if i see resistance on the charts...also, after the move up, look at the position...it inherently gets you long over time...be carefull you might have to sell stock just to stay neutral...not a bad thing if you are selling after a move up...ratios can be looked at in many ways...the seat of your pants(if you collect 500/day..can you loose LESS then that consistantly?...then add weekends and you're doing great)... or look at average daily vol and st. deviation..if you collect 500/day...what are the chances of the stock moving enough to loose that amount...a lot of guys set arbitrary points...if they are comfortable holding 1000 delta, when the position reaches that number they may hedge 1/2 to 3/4
if stock moves up big , wouldn't vols go higher ( due to calls become ITM = skew) ? If yes , you need to buy even more stock to stay neutral , but definetly not to sell , no ?
