The major U.S. index futures are currently pointing to modestly lower open on Tuesday, with stocks likely to give back ground after ending the previous session mostly higher.

Uncertainty ahead of the release of key U.S. economic data in the coming days may lead some traders to cash in on yesterday’s gains.

The monthly jobs report as well as a report on personal income and spending that includes the Federal Reserve’s preferred inflation readings are likely to be in the spotlight.

Reports on third quarter GDP, pending home sales and manufacturing sector activity may also attract some attention.

The data could impact the outlook for the economy as well as expectations regarding how quickly the Fed will lower interest rates.

Traders are also looking ahead to the release of earnings news from big-name tech companies, with Google parent Alphabet (NASDAQ:GOOGL) and Advanced Micro Devices (NASDAQ:AMD) among the companies due to report their quarterly results after the close of today’s trading.

Shares of Ford (NYSE:F) are likely to come under pressure after the auto giant reported better than expected third quarter earnings but forecast full-year earnings toward the low end of its previous guidance.

Fast food giant McDonald’s (NYSE:MCD) is also seeing pre-market weakness despite reporting third quart results that exceeded analyst estimates on both the top and bottom lines.

Meanwhile, shares of Pfizer (NYSE:PFE) are likely to see initial strength after the drug giant beat third quarter estimates and raised its full-year guidance.

After showing a strong move to the upside early in the session, stocks gave back ground over the course of the trading day on Monday but managed to end the day mostly higher. The major averages all finished the day in positive territory after turning in mixed performances over the two previous sessions.

The Dow advanced 273.17 points or 0.7 percent to 42,387.57, the Nasdaq climbed 48.58 points or 0.3 percent to 18,567.19 and the S&P 500 rose 15.40 points or 0.3 percent to 5,821.52.

The strength on Wall Street comes amid a steep drop by the price of oil. Oil prices plunged after Israel’s retaliatory attack against Iran over the weekend did not damage the Islamic republic’s energy facilities.

Meanwhile, traders were also looking ahead to the release of key U.S. economic data later in the week.

Airline stocks saw substantial strength on the day, with the NYSE Arca Airline Index soaring by 3.0 percent to its best closing level in over a year.

Delta Air Lines (NYSE:DAL) posted a standout gain after filing a lawsuit against CrowdStrike (NASDAQ:CRWD) over the July outage that led to thousands of flight cancellations.

Significant was also visible among steel stocks, as reflected by the 3.0 percent surge by the NYSE Arca Steel Index.

Financial, computer hardware and biotechnology stocks also saw considerable strength, while energy stocks moved to the downside along with the price of crude oil.
