Dollar slumps against yen

U.S. stocks fell Tuesday as a sharp drop in McDonald's Corp. weighed on sentiment and as the market braced for Apple Inc. results due after the closing bell. Investors were also reluctant to carve out big positions as the Federal Reserve kicked off its two-day monetary policy meeting.

The large-cap S&P 500 index edged down 2 points to 2,166. Materials were the best performers while telecom and utilities stocks were the biggest losers.

The Nasdaq Composite Index bounced back to rise 9 points, or 0.2%, to 5,106.

The Dow Jones Industrial Average fell 50 points, or 0.3%, to 18,442, dragged down by McDonald's (MCD), which slumped 4.6%. The world's largest fast-food restaurant chain reported slower-than-expected same-store sales (http://www.marketwatch.com/story/mcdonalds-same-store-sales-growth-falls-short-2016-07-26-94855930), pressuring the blue chip index.

Apple(AAPL), another Dow component, is scheduled to release fiscal third-quarter earnings with the tech giant widely expected to post a drop in earnings per share from a year earlier as iPhone sales continue to shrink. Apple shares are off 0.7% and down 8.2% this year.

"Sentiment towards the stock in the investment community is as negative as we can remember, at least in the post-iPod era," according to Bespoke Investment Group, which illustrated Apple stock's decline over the past three years in this chart:

Investors were also reluctant to place any significant bets ahead of the Federal Open Market Committee's interest-rate decision on Wednesday, according to analysts. The central bank's meeting is its first gathering since the U.K. voted to leave the European Union on June 23.

"No one on the Street is looking for any movement by the Fed at this meeting," Bob Pavlik, chief market strategist at Boston Private Wealth LLC, said in emailed comments. "Any commentary referencing an improved operating environment will lead more to believe a September rate hike is looking more likely."

Meanwhile, investors shrugged off positive news from the housing market, where new home sales in June rose to a seven-year high (http://www.marketwatch.com/story/new-home-sales-power-ahead-rising-to-7-year-high-592000-annual-pace-2016-07-26)while the Case-Shiller home-price index also inched higher in May. Instead, the market was bracing for a deluge of earnings.

"Right now everyone is--rightfully or wrongfully--focusing completely on Fed policy and earnings," said Kent Engelke, chief economic strategist at Capitol Securities Management.

Though the central bank is expected to hold interest-rates steady, there are more risks to the downside stemming from the content of its policy statement, according to Engelke.

"If the Fed comes out more hawkishly and earnings disappoint, [the Dow] could plunge up to 1,000 points," Engelke said, adding that there is a lot of "nervousness" which has sparked some profit-taking.

Earnings:

Verizon Communications Inc. (VZ) fell 2% despite reporting second-quarter earnings that beat forecasts (http://www.marketwatch.com/story/verizon-q2-earnings-negatively-impacted-by-union-strike-but-above-expectations-2016-07-26).

A measure of consumer confidence (http://www.marketwatch.com/story/consumer-confidence-holds-steady-in-july-2016-07-26) from the Conference Board held steady in July, suggesting Americans are 'cautiously optimistic" that the U.S. economy will continue to grow.

Other markets: The dollar fell against most other major currencies and particularly took a dive against the yen (http://www.marketwatch.com/story/yen-surges-against-dollar-other-rivals-as-japan-stimulus-plan-falls-short-2016-07-26) ahead of the Bank of Japan meeting on Friday. Expectations that the central bank will launch more aggressive monetary easing have started to fade, sending the yen to its highest level against the greenback since mid-July.

   Oil prices   continued to lose ground, while gold  edged down to settle at $1,320.80 an ounce. 

Asian stock markets mostly rose, although Japan closed lower (http://www.marketwatch.com/story/nikkei-falls-after-disappointing-report-on-stimulus-plan-2016-07-25).
