After weeks of worries about the economy pulled stocks down, indexes have risen sharply for two days in a row.

The Dow Jones industrial average rose more than 140 points Tuesday, thanks in part to signs that concerns of a global slowdown may be overblown.

Quarterly results from Nike Inc. bested analysts' expectations and sent its stock up 10 percent. That helped lead to a rally in stocks of clothing stores, restaurants and jewelers. Such companies tend to do well when consumers are less worried about things like high gas prices and are willing to spend on themselves.

Other industries that do well during periods of economic expansion led the stock market higher. Caterpillar Inc., one of the 30 stocks that make up the Dow, gained the most, rising 3 percent. Industrials gained 1.5 percent overall. Consumer discretionary companies gained 1.9 percent.

Both sectors are still well below their highs for the year. Industrials and consumer companies have lost 5.8 percent and 3.6 percent, respectively, since peaking on April 29.

The Dow gained 145.13 points, or 1.2 percent, to 12,188.69. The Standard & Poor's 500 index rose 16.57, or 1.3 percent, to 1,296.67. The Nasdaq composite index added 41.03, or 1.5 percent, to 2,729.31. All three indexes are down more than 3 percent for the month.

Signs that the housing market is improving helped lift Home Depot Inc. It's sales benefit when consumers spend money on home improvement. Home Depot gained 2.4 percent following a report that home prices rose in April in 13 of the 20 cities tracked by the Standard & Poor's/Case-Shiller index. The index rose for the first time in eight months thanks to an annual push to buy homes in the spring.
