How would anybody know what the open is going to be on Tuesday after the trading halt?

Unless somebody knew there was going to be super news - why would anybody be willing to pay more than 50% of the prior price at TH

And why would there be rumor of such unless people were discussing what they knew and the prices they were going to offer after the news is released?

I'm new to this stock, and looking to free up some funds on Monday to then consider putting into GBR on Tuesday after seeing any release.

But if the ship is so leaky that people are discussing wanting to buy at twice the price before the leaking/buying started - then I might look towards a stock that won't cost me money because of inside trading.
