SAN FRANCISCO (MarketWatch) -- Investors will pick through several economic reports this week, but attention is likely to focus on jobs numbers due on Friday.

Stocks finished lower last week with a big selloff on Thursday that left many investors scrambling. On the week, the Dow Jones Industrial Average (DJI) declined 1%, the S&P 500 Index (SPX) fell 1.4%, and the Nasdaq Composite Index (RIXF) was down 1.5%.

Just the passage from September to October could be enough to amp up volatility in stocks. The CBOE Volatility Index (VIX) rose 22% to 14.80 in the past week alone.

On Friday, GDP growth was revised upward to 4.6% on the back of business investment. Still, investors need convincing that will translate into jobs.

"Everybody sees the slow pace of the economic recovery but not at the level they want it to be," said Robert Pavlik, chief market strategist at Banyan Partners. "They're not seeing the big jobs growth."

Analysts surveyed by MarketWatch expect the addition of 220,000 jobs for September, up from August's 142,000 jobs. Pavlik said he thinks most people expect that August number to be revised higher, perhaps as high as 200,000, with September figures beating estimates.

Other data due this week include August consumer spending and personal income figures on Monday, the Chicago PMI and consumer confidence data on Tuesday, and the ISM manufacturing index on Wednesday.

Stocks are likely to be choppy, however, as real bargains are scarce and buying-the-dip mentality is prevalent.

"I don't see the market falling backwards, maybe taking a step back as retail investors and hedge funds try to game this thing," Pavlik said.

Relatively quiet earnings until mid October

This week will be relatively quiet on the earnings front with a few companies reporting such as Cintas Corp. (CTAS) on Monday, Walgreen Co. (WAG) on Tuesday, and McCormick & Co. (MKC) and Constellation Brands Inc. (STZ) on Thursday.

Earnings won't ramp up until mid-October, when the major banks report, but concern still remains that a rise in the dollar will undercut results from companies that have a significant international presence.

A stronger dollar is a symptom that international economic growth is slowing down, said Barclays strategist Jonathan Glionna in a recent note.

Glionna said the tech and industrial sectors are heavily exposed to international sales and that the energy and materials sectors are doubly exposed because commodity prices are linked to the dollar.

It remains to be seen whether a stronger dollar will cut into earnings this season. Nike Inc. (NKE), which reported Thursday, topped Wall Street estimates even though it has a large exposure to international sales.
