So, to start off, Walmart is currently a stock in one of my backtested strategy's that does about 0.16% per day on average.
The setup is clearly a wedge, and I'd kinda expect it to pop in a day or two here. When WMT moves it tends to do so explosively after a week or so of consolidation, so it's actually a really nice setup. If it doesn't move in a day or two I'll redefine a range and wait for another breakout. I think when it does break out it'll move a few percent in a week. My stop will be either a new low of the range, or a failure to breakout tomorrow.
