I had a good start of 2018, make over 14k on $MU $CNET and $XNET.
Never expected a 30% drop of the stock I picked and held over night (mistake 1: holding something risky over night/weekend), by Friday before stock market open, there was a bad news about the stock and the stock started crushing, and I made my second mistake: added more position to average it up instead cut loss quickly. ( could have been $2k loss instead of 6k loss). The stock kept crushing and I made my 3rd mistake: added margin and bought more shares the second day. (6k loss became 11k loss).
Lessons well learned. Will post this trade when I feel like it.
Good luck all.
