Alcon shares of the Swiss based medical equipment maker are up $2.75 to $144.30 and option volume is 4x the daily average. Notable transactions are were in the Dec $150 and $155 calls traded 2,500 times in what could both be sales while the February $155 calls which traded 5,000 times at $4.90 a contract. Prior open interest in each strike was less than 250 contracts so this should translate into fresh positioning. Possibly sale of the Dec call to finance purchase of the Feb.
