When investors think about the stock market, they tend to focus on broad indices like the S&P 500 or Dow Jones Industrial Average. While this is a natural starting point, it’s often helpful to look one level deeper at the sectors within each index. For instance, the 11 sectors that make up the S&P 500 each have unique characteristics and can behave differently based on economic conditions and geopolitical developments. Understanding these dynamics is important for portfolio construction, diversification, and long-term financial planning.

As you have seen in the news, the U.S. and Israel have launched military strikes against Iran, targeting its leadership, military assets, and nuclear infrastructure. Iran's Supreme Leader is confirmed to have been killed, and Iran has retaliated with missile and drone attacks across the Middle East. President Trump has stated that the goal of the operation, dubbed "Operation Epic Fury," is regime change in Tehran, with strikes expected to continue for weeks and a number of U.S. troop casualties already reported.

February is a reminder to investors that markets never move in a straight line. After January's positive momentum carried major indices to new all-time highs, the mood shifted due to a landmark Supreme Court ruling on tariffs, concerns around artificial intelligence, softer labor market data, and major escalations in the Middle East. Meanwhile, international stocks and small caps continued to outperform, and bonds saw further gains, highlighting the importance of holding a balanced portfolio.
