Dow Jones vs S&P 500: What Makes Them Move?

Have you wondered what makes major market indices like the Dow Jones & S&P 500 move?

Ever wonder why the Dow will be up 400-500 points, while the S&P 500 is down 50-100 points on the same day?

The answer is pretty straightforward…

Not all indices are created equal.

One of the big differences is what causes price movement in both of these major market indices.

In yesterday’s MarketMinds, Scott Bauer broke down the differences between stocks, ETFs, and market indices. He spent part of yesterday’s episode outlining the two major types of market indices, which is which (for the Dow and S&P 500), the factors that drive movement in each one, along with the pros and cons for each index type.

  • The differences between price-weighted and market cap-weighted indices
  • The big role mega-cap stocks (like the Magnificent 7) play in the S&P 500
  • Calculating the S&P 500’s value
  • Which market index is simpler to understand
  • How the Dow Jones can get skewed by high stock prices
