Sold BABA (Gain) and a majority of SIAF (lose) in June. Used the Loses of SIAF to Off set the Cap Gains (90+ PPS)on BABA. Bought back BABA on 11/12/2018 the day after Single Day 11-11 at $142,00 PPS. I'm doing OK. You have to use your loses to your advantage. NOT sit on them. Still have a few thousand shares of SIAF that I will use AGAIN to Offset Cap Gains in the Future.
Hope YOUR plan works for you, MY plan works for me. Good luck
