U.S. stocks are unlikely to break above a key technical level this week unless monthly jobs data and consumer company results paint a more promising picture of the recovery.

The Standard & Poor's 500 <.SPX> index has been stuck near its 200-day moving average, a level used to determine market direction, amid recent weak economic data and disappointing outlooks from companies, including tech companies Nvidia Corp and Symantec .

Options market activity points to more tech sector volatility this week, while the Nasdaq <.IXIC> had the poorest performance of the three major indexes last week.

Among companies expected to report this week are Procter & Gamble and Clorox whose results could give another glimpse into the strength of consumer spending or its lack of spending.

But the government's nonfarm payrolls report, due Friday, looms large since sluggish job growth is considered the biggest hurdle to advances by the economy and stocks.

The Labor Department report follows data Friday that showed the pace of U.S. economic growth slowed in the second quarter. The June labor report showed a fall in payrolls, both of which raised concerns about the recovery for the rest of the year.

We have been reducing our exposure to equities because we are concerned that a weaker economy is going to continue throughout the end of year, said Joseph Battipaglia, a market strategist at Stifel Nicolaus in Yardley, Pennsylvania.


Analysts say a significant break above the S&P 500's 200-day moving average, currently around 1,114, would be a bullish signal.

The market has the potential to push higher again if we can get through the 200-day moving average, said Michael Sheldon, chief market strategist at RDM Financial in Westport, Connecticut.

Chris Burba, a short-term market technician at Standard & Poor's in New York, noted that the 200-day moving average has been nearly flat since late June, which supports the view that investors should be cautious.

The U.S. economy has shown weakness in recent months after a recovery from the worst recession since the 1930s, and corporate results for the second quarter have been mixed.

Earnings growth for S&P 500 companies in the second quarter is expected at 36 percent, while revenue growth is seen at about 9.1 percent, according to Thomson Reuters data.

Options investors appear to be expecting more volatility in the technology sector, which heavily weighed on the market last week, to continue.

The most active options on PowerShares QQQ Trust ETF , an exchange-traded fund that tracks the benchmark Nasdaq 100 <.NDX>, was the weekly put options at the $45 strike, which expire on August 6. Weeklys are options listed with approximately one week to expiration, different from traditional options that have a life of months or years before expiration.

Puts are dominating in the QQQQ, both in weeklys and regulars, said Ryan Detrick, senior technical strategist at Schaeffer's Investment Research in Cincinnati, Ohio.

Regular put options at the August $45 and $46 strikes were also seeing heavy volume. The ETF is currently down 0.4 percent at $45.55.

Some options market analysts see more range-bound trading ahead, with top end at 1,120 on the S&P 500 and the bottom end at 1,065.

In order to take out the upside of the trading range, we need to see the majority of economic data (this) week to be better than expected, said Stifel Nicolaus options market strategist Elliot Spar in Shrewsbury, New Jersey.

In other key economic data this week, the Institute for Supply Management's manufacturing report, due Monday, is expected to show growth for a 12th straight month.
