Geopolitical shocks — terrorist acts, wars or military action — can give your portfolio a significant negative charge. The leading geopolitical source of market instability in 2025 has been the Middle East, as in years past. Israel’s decision to attack nuclear facilities in Iran in an attempt to retard that country’s weaponization efforts prompted a 1.1% drop in the S&P 500 index on June 13.
Among the losers that day, according to S&P Global Market Intelligence, were leisure-travel companies Norwegian Cruise Line Holdings (NCLH) and Carnival Corp. (CCL), which each fell about 5%. Other travel and leisure companies that fell at least 3% that day included United Airlines (UAL) and Delta Air Lines (DAL); Caesars Entertainment (CZR), MGM Resorts (MGM), Las Vegas Sands (LVS), and Wynn Resorts (WYNN); Expedia Group (EXPE); and Marriott International (MAR). Several energy and agricultural companies and defense contractors gained at least 2% that day.
