NOV is trading 4.84% down at $19.55 after weaker order momentum and a cautious fourth-quarter outlook following its October 27 earnings report. - Third-quarter revenue was $2.23 billion, while bookings of $577 million yielded a 91% book-to-bill ratio. - Fourth-quarter revenue is expected to be roughly flat year over year; adjusted EBITDA guidance is $260–$300 million. Energy-sector weakness may add pressure, but earnings and outlook are the clearer company-specific catalyst.
