What's behind call action in ViroPharma

VPHM hit $31 this morning, its highest intraday price since 2001, but pulled back and is now up 0.76 percent on the day at $30.33. The stock has doubled in the last six months from 52-week lows below $15.
The drug developer is not a typical name for institutional option traders, as it has an average turnover of just 552 contracts a day. But today that volume is almost 10 times higher.
optionMONSTER's systems show that a trader sold 4,999 March 30 calls for $2.70. The previous open interest was just 156 contracts, so this is clearly a new position.
The activity is not tied to any trading in the underlying shares that we can see. Nevertheless, given that it is in-the-money call selling, it is almost certainly tied to a long stock position.
The trader is looking to collect that option premium and sees relatively stable prices for the stock in the next month. This trader may be trying to sell shares but wants to do so for the premium that the option sale affords. (See our Education section)
