I was looking back at the 2 year SPY chart at every correction we have had over the last 2 years and this is the weakest bounce out of all of them. Most of the bounces were "snap-backs" within just a few days. Take a look at the 2 year chart and see for yourself how weak this bounce has been compared to past corrections.
No buyers left.
That's because this whole market is built on phony money that was pumped in by the fed, and the real pros now fear and know the music is close to stop playing, and there will be a major shortage of chairs to sit in when it does stop playing, many of them are not willing to put on there best dancing shoes when the music is blasting and take the loud music as a clue to find a chair and get ready to sit in it.
each of hard bounces you mention came off the 200 dma. Take a look. People claim moving averages are nonexistent in terms of relevance. Maybe so, but that's one hell of a coincidence if they're correct.
