A couple of notable upside movers on a day where the market declined. First, AER gained after announcing its was purchasing the aircraft leasing business of AIG. Strangely enough, the shares of AER gained despite being the purchaser here. Investors see some value being added here. Second, XLS shares gained after the company announced its was spinning off its government-related business. I am intrigued not only because XLS gained, but spin-offs tend to outperform after separating from the parent firm.
