the option MM usually hold the bid and ask price down when the stock make sharp moves in a short period of time. He will hold the price to get a even bid or ask, unless there are huge volume, he can usually take bids off the level II, then he will rematch these trades later, that is how he makes money.
did you check the delta on your options before you buy? the Delta on your option is 0.333. plus not alot of open interest, so the MM can maniuplate anyway he wants, doesn't require him much margins to push the price down. They do that to sirius options all day long. even right after I bought some at 50 cents, the last trade on the tape still said 48 cents, which compress the margin.
