When a stock runs up verticall like KXL has, it is quite common for it to retrace.
A friend of mine is counting on that to let him get a position more cheaply. This has not happened thus far with KXL. Personally, I do not think it will happen.
Here is the chart. While it is scary-vertical, I am quite impressed with the level of accumulation taking place by smart money, as shown by the continuing strength in the On Balance Volume (the chart I use above and below the price).
