Occasionally I will make lots of money from speculative issues offering a great R:R setup. Recently, I've done that with ASTI: http://bp2.blogger.com/_znF9pQ5oe98/R3XhlMVjh6I/AAAAAAAAAB4/kcewrnJWf5U/s1600-h/ASTI.PNG In November the stock saw a -42% decline while many other solars were being hit -15% in one day. I sold on 50-dma breakdown. Now.. what I'm debating about with myself is whether it was worth holding my initial buy through that decline. Any other less volatile stock would've had its technical pattern obliterated, but even with the -%42 decline ASTI still had the potential to form a double base, which it did. Since I want to optimize my performance for the next speculative issue, what are some suggestions to manage risk? How much profit should I protect? So far I've come up with the idea of protecting %50 of profits after a +%30 run from a breakout. However, I'm still unsure of the effectiveness. In ASTI it definitely would not have worked. Any ideas for such trades?
