Netflix stock is up big this morning after the streaming giant added more than 13 million subscribers in the 4th quarter as a crackdown on password sharing and a new ad-supported price tier has attracted new viewers. Elsewhere policy makers are rolling out near-daily initiatives in China in an effort to stop the bloodletting in their stock market. This morning there are defacto bans on shorting index futures and a cut in the Reserve Requirement Ratio for Chinese banks. These measures weren't enough to save Dupont's earnings which saw a big hit from Chinese demand. Also DR Horton is the first sign of weakness showing in the housing market.
