Here is an interesting article on recent stock market movement from Mike Harris(I guy I follow on twitter @MikeHarrisNY). http://www.priceactionlab.com/Blog/2018/10/sp-500-back-to-back-gains/ S&P 500 Now 27 Days Without Back-to-Back Gains Since AIM can be considered a volatility capture engine, there would have been interesting trade potential due to this phenomenon. Thought you may find it interesting.
