HNSN

Today's unusual options trading, from whatstrading.com.

HNSN is seeing very heavy volume in Dec 2.50 puts. Since this had no prior open interest, I would imagine that this is one trader opening this position. The size of the position is just mind boggling.

Here is the chart for HNSN, which just offered a 3 million share secondary, further diluting the already underwater shareholders. 2.50 puts seem a pretty good bet here, but the questions I have are: 1) why December? and 2) who the hell wrote all those puts?
