Furthermore, parallels have also been drawn between Facebook Inc (NASDAQ: FB )'s first day on the options market, nearly two years ago and Alibaba Group Holding Ltd (NYSE:BABA)'s upcoming debut. According to Rochan, a senior options analyst at online brokerage TradeKing, Brian Overby expected Alibaba's option trading volumes on the first day to be about a fourth of Facebook's when the owner of the renowned social media platform first appeared on the option trading boards. In fact, Facebook currently holds the record for the first day option trading volume. Rochan said that on its debut, 365,000 options contracts changed hands. Another interesting fact mentioned by the other regarding that historical day was the put-call ratio of the trading volume. Put options were in the lead and exceeded calls by 1.25:1.
