US stocks edged lower  on caution ahead of an all-important jobs report, but the S&P 500 still posted its best monthly gain since October 2011.

The benchmark S&P 500 advanced 5.1 per cent in January as investors cheered a compromise that temporarily postponed the impact of the ‘‘fiscal cliff’’ and fourth-quarter earnings were better than expected.

The S&P 500 registered its largest monthly advance since a rise of more than 6 per cent in October 2011 and the best January showing since a 6.1 per cent jump in 1997. For the month, the Dow gained 5.8 per cent and the Nasdaq rose 4.1 per cent.

Investors expect a pullback in equities after the recent gains, though they have bought on dips over the past four weeks. The largest daily decline on the S&P 500 so far in 2013 was Wednesday’s 0.39 per cent drop after data showed the economy contracted in the fourth quarter of 2012.

The government is due to release January’s employment figures on Friday. Economists polled by Reuters expect non-farm payrolls to show employers added 160,000 jobs compared with a rise of 155,000 in December. The unemployment rate is likely to hold steady at 7.8 per cent.

A survey by payroll processing company ADP  showed private sector employment rose higher than expected in December but the government’s measure of jobless benefits claims increased last week.

‘‘It’s the calm before the potential storm. The uncertainty about tomorrow’s numbers comes from that fact that we had a decent ADP report but the weekly claims were not so great,’’ said Randy Frederick, managing director of active trading and derivatives for Charles Schwab in Austin, Texas.

In a separate report, the Commerce Department said American incomes rose 2.6 per cent last month, the biggest increase since December 2004.

‘‘We could see an overly sensitive market to a bad number tomorrow, given that we’ve been up without a major correction, and that makes the market sensitive to the downside.’’

Friday will also bring reports on consumer confidence, US manufacturing, construction spending and car sales.

Limiting losses on the Nasdaq composite index, Qualcomm gained 3.9 per cent to $66.02 after the world’s leading supplier of chips for cellphones beat analysts’ expectations for quarterly profit and revenue and raised its targets for the year.

Facebook shares fell 0.8 per cent to $30.98 after falling as low as $28.74 a day after the social network company said it doubled its mobile advertising revenue in the fourth quarter. However, growth trailed some of Wall Street’s most aggressive estimates.

The Dow Jones industrial average was down 49.84 points, or 0.36 per cent, at 13,860.58. The Standard & Poor’s 500 Index was down 3.85 points, or 0.26 per cent, at 1498.11. The Nasdaq Composite Index was down 0.18 points, or 0.01 per cent, at 3142.13.

Constellation Brands shares tumbled 17.4 per cent to $32.36 after the US Justice Department moved to stop Anheuser-Busch InBev from buying the half of Mexican brewer Grupo Modelo that it does not already own. Constellation would have distributed Corona beer in the United States if the transaction had been approved.
