Netflix is down 5% to $320.60.
This sell-off is being partly attributed to Verizon's win over the Federal Communications Commission's (FCC) net neutrality rule.

The decision against the 'net neutrality' rule, would potentially increase costs for Netflix.
Netflix is currently trying to ramp up original programming while also investing in obtaining rights to TV shows and movies. If Netflix had to pay a higher fee to internet providers this would increase costs and weigh on profits.
