ON Aug 31, 2016 I asserted that it's possible to do a bear call spread without risk. That was in a blog post on blog.radioactivetrading.com. ON Sep 16 the SlideShare revealing the details was published.
Now, more than a week before the spread expires, the net position is "Bulletproof", meaning that it's no longer possible to lose money, but we'd be happy if the stock goes up OR down.
Check out these slides and see what you think.
