Political Polarization and U.S. Equities: Sector-Specific Opportunities in Media, Defense, and Tech

Political polarization in the United States has evolved from a societal challenge into a market-defining force, reshaping investment dynamics across key sectors. As ideological divides deepen, investors are recalibrating strategies to capitalize on opportunities in media, defense, and technology—industries directly influenced by the political and regulatory landscape.
