Market Wrap for Tuesday, July 30: Technology Sector Rises; Basic Materials Hit Hard

The U.S. stock market closed near the unchanged line on Tuesday as earnings season continued with another full-slate of corporate results. Most of the day's gains were concentrated in Nasdaq stocks, as the technology sector led that market higher. Energy, basic materials and financials were the only three sectors to post losses on the day. Basic materials were hit very hard in the wake of a falling out between two foreign potash manufacturers which analysts said will trigger an immediate decline in potash prices. Volatility was limited in other asset classes, although crude oil recorded a loss of over 1 percent on the day. The U.S. Dollar was slightly higher on the session while Treasury prices were largely unchanged. On the economic front, an index measuring consumer confidence in July missed expectations by a narrow margin.

The Dow Jones Industrial Average fell a little more than 1 point, or 0.01 percent, to close at 15,521. The S&P 500 added less than a point, or 0.04 percent, to finish at 1,686. The Nasdaq rose around 17 points, or 0.48 percent, to finish at 3,616.

The Conference Board's Consumer Confidence Index fell slightly in July. The gauge of consumer sentiment came in at 80.3, which compared to a reading of 82.1 last month. This was below consensus estimates which expected that the index would decline to 81.6 for the month.

Crude oil futures fell on Tuesday. At last check, NYMEX crude futures were trading down 1.37 percent to $103.12. Brent crude futures had lost 0.50 percent and were last trading at $106.71 as the spread between WTI crude and Brent has widened slightly in recent days. Natural gas lost almost 1 percent on the day to $3.44. Precious metals recorded modest losses on the session. COMEX gold futures had shed 0.23 percent while silver contracts were last down 0.75 percent to $19.72. Copper futures fell more than 2 percent on Tuesday to $3.0410. In the grains complex, both corn and wheat climbed on the day. Corn futures rose 0.90 percent while wheat added 0.58 percent. Movers in soft commodities included coffee and lumber. Coffee futures fell 0.70 percent while lumber was down 1.25 percent.

The U.S. Dollar was slightly higher on the session. Approaching the closing bell, the PowerShares DB US Dollar Index Bullish ETF

, which tracks the performance of the greenback versus a basket of foreign currencies, was up 0.20 percent to $22.15. The closely watched EUR/USD pair was last down 0.02 percent to $1.3264. Other movers included the GBP/USD, which fell 0.74 percent and the AUD/USD, which was down 1.51 percent.
