A Director Sold Almost 2 Million Shares of This Oilfield Services Company After a Big Run. Should Investors Follow?

Director Yousif Mohammed Ali Nasser Al-Nowais sold 1,919,594 shares (89.33% of his holdings) of National Energy Services Reunited Corp. (NESR) for $51.5 million on June 25, 2026, following a 363.6% year-over-year stock surge. While insider selling after significant gains can raise questions, the article cautions against over-interpreting such moves, especially when conducted through holding companies. NESR faces a headwind as it was removed from Russell indexes on June 27, which could trigger mechanical selling from passive funds, though this was due to index reconstruction rather than company-specific issues.
