A busy calendar and new challenges will rock markets this week

The stock market wasn't supposed to open 2025 with a thud. That, at least, was the conventional wisdom. The big rally that erupted after the election of Donald Trump in November was supposed to continue well into the new year.

Instead, stocks have surprised by sinking, starting in early December. The issue: Long-term bond yields continued a surge that began in mid-September.

Add to that primary cause:

  • The uncertainty surrounding President-elect Trump's agenda, especially on tariffs and deportations.

  • Weakness in some key market sectors, including technology.

  • Oil prices and gasoline prices that seem be inching higher.

  • How the Los Angeles wild fires will weigh on the rest of the domestic economy. Remember, the population of Los Angeles County alone is larger than those of 40 states. (Its area is larger than Rhode Island and Delaware combined.)

These factors set up a potentially volatile week for markets in the week before Donald Trump's inauguration on Jan. 20. The week will be dominated by two key inflation reports on Tuesday and Wednesday and a host of earnings, especially from financial companies.

Here are the numbers at week's end.

The 10-year Treasury yield: 4.769%, the highest level since May and up from a low of 3.6% in September. It is the primary determinant of mortgage rates and the health of the housing.

The rate on a 30-year mortgage: Somewhere between 6.95% and 7.3%. Lenders have been seeing interest in home buying and financing fade in recent weeks. Rates at 6% or lower seem to generate excitement.

Stock indexes: Standard & Poor's 500 Index: Down 1.9% for the week and 4.5% since its all-time high of 6,099.97 on Dec. 6. Dow Jones Industrial Average: Down nearly 700 points on Friday, down 2.5% for the week and 7% from its December peak. The Nasdaq Composite Index: Down 460 points, or 2.3% on the week and down 5.2% since its Dec. 16 all-time high.

Key stocks: Apple  (AAPL)  is down 5.4% since Dec. 31. Nvidia  (NVDA)  is up 1.2%. Microsoft  (MSFT)  has slid 0.6%. Tesla  (TSLA)  has slipped 2.3%. Walt Disney  (DIS)  has dropped 2.4%.

The pullback so far is not usual

If you worry that markets are about crash, hold on. Stocks typically decline 5% or more three times a year, 10% or more once a year and 20% once every 6.3 years, according to mutual fund company Capital Group.
