Apple drops; Twitter recovers off intraday low

U.S. stocks slid into the red following a morning of switching between gains and losses Tuesday, as investors await a batch of economic reports headlined by the key jobs reports due later in the week.

Shares of Apple Inc.(AAPL) fell more than 3%, limiting gains on the main indexes. Read: Apple's stock drops below 2 bearish technical levels (http://www.marketwatch.com/story/apples-stock-drops-below-2-bearish-technical-thresholds-2015-08-04)

The Dow Jones Industrial Average declined 47 points, or 0.3%, to 17,551.46, the S&P 500 slipped almost 4 points, or off 0.2%, to 2,093, and the Nasdaq Composite Index lost 14 points, or 0.3%, to 5,100.79.

Last week's lackluster wage-growth figures (http://www.marketwatch.com/story/you-can-see-higher-wages-everywhere-but-in-the-data-2015-07-31) and a weak rise in consumer spending (http://www.marketwatch.com/story/consumer-spending-takes-a-cooler-turn-in-june-2015-08-03) are weighing on investors's minds, forcing markets into a sideways situation, said Randy Frederick, managing director at the Schwab Center for Financial Research, in a phone interview.

The early swings in direction follow a weak session from Monday (http://www.marketwatch.com/storyno-meta-for-guid), when all three stock averages closed firmly lower after disappointing U.S. economic data and a slump in oil prices (http://www.marketwatch.com/storyno-meta-for-guid). A report on manufacturing activity came in lower than expected (http://www.marketwatch.com/story/ism-manufacturing-data-released-early-has-soft-tone-2015-08-03), reigniting fears that growth in the world's largest economy is losing momentum.

"It is a tough market for people to trade," Frederick said.

Nicholas Colas, chief market strategist at Convergex, in a Tuesday note warmed that. "August is going to be a long and lonely month for U.S. equity markets."

"Domestic stocks hover at the upper end of comfortable valuations, and market internals aren't helping much to mitigate the volatility that comes with those high price/earnings ratios," Colas said, suggesting that stocks may be more expensive than their fundamental performance can support.

While the Federal Reserve has indicated that it will raise interest rates some time in 2015 unless there is a significant downturn in economic conditions, Colas doesn't see the first rate happening in September, which may be spooking investors.

Data out later this week could also dictate the future trading direction. On Friday, the top-tier nonfarm-payrolls report is due, which will be scrutinized for clues to the strength of the labor-market recovery. The Federal Reserve has said it is watching economic indicators--wages and employment numbers in particular--as it assesses when to hike interest rates.

The ADP employment report, considered a precursor to the nonfarm data, is due on Wednesday.

Factory orders rose 1.8% in June, less than economists surveyed by MarketWatch had expected (http://www.marketwatch.com/story/us-factory-orders-increase-18-in-june-2015-08-04).

There are no Federal Reserve speakers on the docket.
