In addition, questions over whether Russia could be drawn into the conflict in Ukraine will likely weigh on investor sentiment. March futures on the CBOE Volatility index, Wall Street's so-called fear gauge, shot up nearly a percent even as the S&P 500 closed at another record high on Friday.
"It will be interesting to see the action on S&P futures on Sunday night based on the kind of developments we see in Ukraine. There are definitely concerns out there and with the S&P 500 at a record again, it's a great time to buy some protection like the VIX," said JJ Kinahan, chief strategist at T.D. Ameritrade in Chicago.
The spot VIX closed down 0.3 per cent at 14 on Friday.
For the past couple of months, interpreting US economic figures has taken on a familiar pattern: questions are raised about possible weakness in demand, then investors shrug and dismiss it all as a product of bad weather.

"This first quarter macro numbers may be dampened a bit again by the bad weather and some of the impact on the demand," said Natalie Trunow, chief investment officer of equities at Calvert Investment Management, which has about $13 billion in assets. "But I think the overall trend will be positive."
The S&P 500 ended at another record close on Friday but was well off the day's highs after Ukraine's acting president accused Russia of open aggression and said Moscow was following a similar scenario to the one before it went to war with Georgia in 2008.
But overall, Wall Street has been relatively calm to problems in Ukraine and Russia thanks to a better-than-expected earnings season. All three major indexes closed out the month of February with strong gains. The Dow Jones industrial average scored its best monthly percentage gain since January 2013, while the S&P 500 had its best month since October.
