any time you buy or short into earnings you are playing with fire. a good trader never does that. also,i see alot of guys say the same thing"I had to leave my computer for a few minutes and when i returned my account was down twenty percent". that sounds like these traders are trying to convince themselves it really was'nt their fault,it was just a freak occurrence and if it was'nt for some strange set of circumstances that had them leave the computer,the losses never would have happened. thats bs. i've done it and had the same excuse. NEVER let your loss get big. just sell and take a small loss and jump back in if it does what you think. remember,stocks do not follow a script. they should always move in your direction but not always within ypur specific time frame. that said,you will be wrong at times and have got to learn to move on. don't think it has to work just because you think it will.
my biggest losses were holding overnight,onto earnings and buying an opening gap up and watching it fall and doubling down. justb plain stupidity. when a stock starts to drop,the market is actually screaming to you that the trade is'nt working but why don't we listen?
