Financial sector takeaways for investors
Bank stocks may be the first thing that comes to mind when thinking of the financial sector. They make up half of the 10 largest financial companies, but the sector also includes other types of businesses, such as insurance companies and payment networks.
Economic downturns often hit financial stocks hard, banks in particular. During periods of high unemployment, financial companies may be saddled with large amounts of bad debt that they need to write off.
The Trump administration's tariffs and resulting economic uncertainty could be a serious headwind for the banking sector. Chinese bank stocks may be hit especially hard. However, a federal court ruled that most of these tariffs are illegal. For now, the tariffs are still in place, pending an appeal.
Despite the risk of a potential downturn, the top companies in this sector are massive businesses with long track records of success. For patient investors, financial stocks can be a valuable addition to a portfolio.
