I noticed all calls and put were priced at $200,000 each today meaning somebody wanted to stop trading on options on AMSG.

I've seen this before was on a stock that was subsequently taken over. If they stop trading the calls and puts, that ends any possible insider using leverage does it not?

In other words to keep folks honest.

Of course this is pure conjecture since I have no clue as to why those calls:puts price changed to $200,000 today:
