The New York equities markets were lower at midday.

The Dow Jones Industrial Average was 0.69 percent lower to 13,858.80, while the Nasdaq Composite had dropped 0.54 percent to 2,676.18 and the S&P 500 was down 0.69 percent to 1,530.96.

Part of the declines came as quarterly reports disappointed.

In the chemicals sector, DuPont (NYSE: DDPRA, DDPRB, DD) reported that profits did not grow in the second quarter even as sales were better overseas.

DuPont had dropped $2.96 to $50.30 by mid-session.

Texas Instruments (NYSE: TXN) fell $1.32 to $36.86 as it reported profits lower than the same time last year.

Fast food chain McDonald’s (NYSE: MCD) was 33 cents lower to $52.17 after it reported a losing quarter on a charge growing out of its sale of Latin American outlets.

AT&T (NYSE: T) was 18 cents higher to $40.21 after it said that its earnings were up by 61 percent in the second quarter, but reported that fewer Apple iPhone numbers than had been anticipated were activated following the new phone’s release.

Apple (NAS: AAPL) dropped $3.88 to $139.82 on the news of fewer iPhone activations and ahead of its quarterly report, due on Wednesday.

Companies exposed to bad loans were lower.

American Express (NYSE: AXP) dropped $1.94 to $62.72 after it reported an increase in write-downs on bad loans in the second quarter.

Meanwhile, mortgage lender Countrywide Financial (NYSE: CFC) fell $3.08 to $30.98 after it reported significantly lower profits in the second quarter and cut its earnings forecast.

Wall Street saw gains at midday on Tuesday, with the Dow Jones Industrial Average up 0.35 percent to 12,520.91, the Nasdaq Composite 0.41 percent higher to 2,441.12, and the S&P 500 adding 0.34 percent to 1,427.75. The Russell 2000 index of small-caps was up even more, gaining 1.01 percent to 785.82. Volume at mid-session was at 712.8 million shares.

The banking sector was mixed. Bank of America was 40 cents lower to $53.25 even though it said its loan business was up and that its purchase of credit-card company MNBA helped profit in the fourth quarter. Wachovia was up , but only by 4 cents to $56.3 even though issued a better than anticipated report.

In the oil sector, higher prices due to forecasts of colder weather sent Chevron up 97 cents to $72.21, while ExxonMobil gained $1.12 to $74.03 and ConocoPhillips added $1.41 to $64.78.

Telecommunications equipment makers saw declines. Tellabs was 4 cents lower to $10.06, while Alcatel-Lucent fell $1.17 to $13.03. Alcatel-Lucent blamed its inability to make a profit in its first quarter after consolidation on integration costs and weak sales.

In the semiconductors sector, Texas Instruments added $1.17 to $29.76 on a positive quarterly report and several broker upgrades.

Even though it reached analysts’ expectations, chemicals company DuPont dropped $1.23 to $48.87 on concerns about the higher cost of raw materials.

The New York equities markets were slightly higher at midday on Monday ahead of the next meeting of the US Federal Reserve and a new decision on interest rates. The Dow Jones Industrial Average was up 0.1 percent to 12,319.42, while the Nasdaq Composite had added 0.4 percent to 2,446.61 and the S&P 500 had gained 0.2 percent to 1,412.61.

Miners were lower on the session so far. Phelps Dodge dropped 0.3 percent to $123.25 after hedge fund SAC Capital Advisors LLC said they had purchased a stake and that it would oppose the effort by Freeport McMoran to buy the company. Freeport McMoran dropped 0.4 percent to $61.56 on the announcement.

The pharmaceuticals sector was still plagued by bad news from drug trials. Nuvelo was 80 percent lower to $3.92 after it said that clinical trials of two blood thinners it was developing were unsuccessful.

Citigroup was 1.4 percent higher to $52.58 on the news that it is bidding for Egg, Prudential’s internet banking unit.

In the chemicals sector, DuPont added 1.4 percent to $47.57 after it said it had upped its earnings forecast for the year from $2.86 per share to $3.25 per share. It also said it will cut 1,500 positions from its agriculture division.

Among technology companies, Cisco added 1.3 percent to $27.33, near its highest level in a year.

The New York equities markets were mixed in early afternoon trade on Tuesday. The Dow Jones Industrial Average was 0.02 percent higher to 12,118.91, while the Nasdaq Composite had dropped 0.4 percent to 2,342.22 and the S&P 500 was 0.1 percent lower to 1,375.57. The activity was a result of several factors, including a lack of new economic data, earnings reports that were not up to par, and unwillingness to commit ahead of the Federal Reserve’s newest interest rate decision, due Wednesday.

Texas Instruments dropped 2.9 percent to $30.97 on a quarterly report that did not meet expectations and on a disappointing prediction for fourth quarter results. Kraft Foods likewise issued a quarterly report that did not satisfy, and was in consequence 3.8 percent lower to $34.91. Even though Whirlpool’s earnings were a bit better than had been anticipated, it cut its prediction for unit shipment growth in North America. The appliance maker saw shares fall 3.9 percent to $85.86.

Not all the quarterly reports were disappointing. DuPont produced a good quarterly report and added 1.8 percent to $46.28. Lucent, which is being purchased by French telecommunications equipment maker Alcatel, added 7.7 percent to $2.52 on better than expected earnings.

Qualcomm was 3.1 percent lower to $36.91 on rumors that the patent case it filed against Nokia could be in for another look by the courts. Meanwhile, Intel added 1.1 percent to $21.69.

Amazon.com added 1.8 percent to $33.46 ahead of its quarterly report, due after the close of trade.

Falling crude oil prices and gains in the retail and homebuilding sectors helped the New York equities markets to gains by the middle of the day on Wednesday after two days of losses. The Dow Jones Industrial Average had climbed 0.6 percent to 11,065.27, while the Nasdaq Composite had added 0.9 percent to 2,181.50 and the S&P 500 was up 0.6 percent to 1,271.15.

The pharmaceuticals sector was up after GlaxoSmithKline said it was considering purchasing Pfizer’s consumer unit if the right price could be reached. This sent shares in Pfizer up 1.1 percent to $24.11. In addition, Abbott Labs gained 1.9 percent to $43.05.

Retailers were up, led by a 3.6 percent gain to $49.31 for Target. In supermarkets, Kroger added 1.9 percent to $20.13, while Supervalu gained 2 percent to $29.39.

After a dismal day on Tuesday, homebuilders were up on the day. DR Horton gained 1.5 percent to $23.75. Pulte, meanwhile, was up 1.9 percent to $28.65.

The chemicals sector was not so fortunate after Deutsche Bank issued downgrades to Dupont and Dow Chemical. Dow was down 0.5 percent to $39.37 and Dupont lost 1.3 percent to $41.64.

While the drop in crude oil prices helped investor sentiment, it did not help the energy sector. Schlumberger and Occidental Petroleum each had lost 1.8 percent by mid-session, to $62.79 and $96.03 respectively.

In much the same way, falling commodities prices sent shares in companies dealing in metals downward. Alcoa was down 2.4 percent to $29.97, while Freeport McMoran dropped 3 percent to $51.22.
