With as wild as the market has been lately and the way our strong upward trend has prevailed in the face of just about any crisis, it's easy to fall into the mindset that "stocks only go up." However, seeing how well Elliott's wave theory fits in the price action of the recent months, I believe we will be seeing a turn soon.
In addition to this, we are nearing the top of just about every regression channel and trendline on every time scale.
