Withing the realm of Options Trading, do most traders tend to specialize on market sectors/industries? IE: Technology (AAPL, GOOG) or Financials (QQQ, BAC) ???

The reason I'm asking (I'm still a noob) is that my day job is in the Pharma industry (aka: Healthcare > Drug Manufacturing) and I already follow industry news.

Is Pharma a good sector for options trading? Or may lack of volume or volatility be a problem?
