I think he is playing the odds. He has a 1:52 chance. Out of 52 weeks in a year, there is a possibility that some GOOD news for GSX will fall on a Thursday. Statistically speaking there is a medium probability that this event will transpire on any given Thursday.
But in his defense, there will be some good news real soon. Will it be on Thursday, well, there is a chance. We will see a nice POP in share price within the next two weeks.
