By Doris Frankel CHICAGO (Reuters) – Trading in options of Twitter Inc was dominated by put volume with a mixture of selling, hedging and speculative activity in an overall orderly debut on the U.S. options market, a week after the social media companys stock started trading. A total of 82,000 puts and 41,000 calls changed hands in Twitter on Friday for a put-to-call ratio of 2:02:1, according to options analytics firm Trade Alert. Option volume was on the low end of expectations, while the underlying shares had a relatively light day of 8 million shares traded The options market has been rather well-behaved from a price, volume and implied volatility perspective, said Tim Biggam, chief market strategist at options firm TradingBlock in Chicago. Twitters turnover did not match the frenzied pace of Facebook Inc, which set a record with its first-day options launch in May 2012, when more than 365,000 contracts changed hands, Trade Alert figures showed.
