Dec 18 (Reuters) - U.S. stock index futures were lower on Friday as a selloff in commodity markets showed no signs of easing.

* Trading could be more volatile than usual on "quadruple-witching" Friday, when options on stocks and indexes as well as futures on indexes and single stocks expire.

* Crude oil prices were heading for their third straight weekly loss as global oversupply continued to pile pressure. Exxon and Chevron shares were down 0.6 percent in premarket trading.

* Global markets fell on Friday, with investors turning wary about the impact of a stronger dollar and weakening commodity prices on the global economy. U.S. stocks closed lower on Thursday, led by declines in energy and materials shares.

* The dollar index, however, shed some of its post-Fed rate hike gains on Friday, after the Bank of Japan reorganized its stimulus program.

* Carnival Corp shares were up 1.2 percent at $51.06, ahead of its quarterly results before the bell.

* Qihoo 360 was up 2.8 percent at $73.80 after the Chinese mobile security software maker said it would be taken private for about $9.3 billion, including about $1.6 billion in debt.   Continuación...
