LNKD options have broken for trading and it is a rather wide market: some indicative markets: July $100 calls: $0.05 bid; $4.70 ask, June $77.50 puts $1.50 by $4.50. Implied vol for ATM calls is about 50 while for puts roughly double, or 100. The most actively traded options early on: $80 June puts, and July $92.50 calls. Everyone should be grateful we have Citadel's HFT team to make markets and add option liquidity.
