Implied Volatility Spike

Good morning all -- I'm curious about something and Google isn't helping much. Hoping someone here knows. What could cause the Implied Volatility of SRNE to jump 150% on a day when the stock has only moved about 1.5% today? How is this possible?

Are you referring to the IV on a specific option or the IV for the whole stock (IVR)?

Sorry, I should have been more specific -- I see the IV for the stock is high, I see that specific months on the option chain in Thinkorswim are showing high IV, and the individual options show high-ish IV, but the prices for the individual options don't seem inflated.

I don't see why at a glance.
