If this french analyst is right, then it is wonderful and funny. According to him, it was a trap successfully done by a group of amateurs who made a coordinated operation to force more experienced investment groups to buy back at lost their positions*
*I don't know how you call this in English, when you sell in advance a stock you do not have, and you expect to buy it later at lower price to earn the difference.
I have never yet tried that, it scares me to play with stocks "from the future".
So some smarts amateur investors planned to make it explode by offering at the open some buy orders at 4 times the prices sometimes, they really triggered a move which forced many investors to buy back their position to desperately limit their lost.
