The Dow Jones industrial average first crossed 23,000 intraday on Oct. 17. Because the Dow is a price-weighted index, the higher-priced stocks typically have a bigger influence on the Dow's movements. This again was the case with the move from 23,000 to 24,000, with higher-priced stocks such as UnitedHealth, Boeing, 3M and Apple all contributing the bulk of the gains.
The one exception is Goldman Sachs, which despite being the second-highest-priced stock in the Dow (after Boeing), contributed only 23 points to the Dow's gain.
Here's a breakdown of the stocks that contributed the most to the Dow's 1,000-point run from 23,000 to 24,000, based on the closing prices on Oct. 17 to the opening prices today.
