Bid is $9.70 Ask is $16.19

I do not recall this before where the spread of the asking price was nearly double the bid. The market price is $10.44.

What causes this? Is this good or bad? Is it an indicator of massive short term growth or expectations? Is it worth buying with a premium that high above market, and what would justify it?
