ALGN might not be over yet.Stock made a high of 370-380 in Sep21 and then fell 75% to $172 in Nov22. It is not new for it. Stock fell more than 60% in 2001-2002, 2004-2005 and 2007-2008. With all of that on a log chart it is forming a rising wedge pattern. 172 is important. Firstly it was the lower end of the wedge and second it has always been a major support for the stock. Looking at the past we can say if the price falls below $172 it always came back and closed above it.
