I don't do any kind of prediction on the market for quite a long time as I prefer to take trades with my system and respect whatever result the market gives.
This one is more an verification idea than a trading idea. GSX stocks had been fallen a lot after the scheme, and it broke the inside week to the downside before ER. I will pretty much be pessimistic about both the ER result and the price.
Well, I still won't take trades before an ER, this is just to see if this inside week breakdown may be some sort of implication of the following price actions.
