I have never owned an option when a stock got halted, Jimmy or Lee might be able to answer that question better, I am definately not an expert on options, just a mid-level option trader. Lee and Jimmy or any of the mods on here for that matter are much more versed with situations like that.
GMCR is not a pink sheet stock or chinese reverse merger!! it won't get halted for cooking the books!!! Just tank to where the market thinks its worth!!
