回复：不得不说的话，还是送给新手/新新手们：

Today's action on SPSC is mainly due to the improper comments by the CEO who doen't how to talk.
Other than that, there is nothing esle before today that signals such a big crash.
SPSC did climb relatively slowly up to that level unlike others perpendiculy lift up, I don't see any technical problem causing this crash.
The market is a uncertainy for sure no matter what methods you use to analyze.
If there is a sure way to make money in the market, no one would like to work, isn't that right? good luck to everyone.
