i had a guy tell me he would move me to dubai if i would do a model for him. "If you can make a short only, dude, Ill pay you in Dubai full time...and include daily ration of Humus" he seemed quite crazily excited it might be possible. i dont trade stocks but they are easy to model so i am working on this thing now. he said "Short is the holy grail"
lol i am working along the lines of getting a signal to go short today for tomorrow open and then if its profitable open position by close tomorrow then set high of that day as the stop. let it run a bit.
Since most institutions are long beta there is demand for such a strategy which is naturally negatively correlated with what they have. However, it is difficult, both technically (you will be a contrarian to most mainstream professionals) and mentally.
it's pretty doable for me mentally cause i am a futures trader who has made lot's of money shorting the sp - it's fast addictive action for me. i believe in shorting, i am comfortable. so even in a uptrend i can easily figure out where to short and about how long it will last using derivatives of velocity. it's strange to me this isn't evidently mainstream. i do have some big losses though, part of the game.
