Stock futures are mixed as big bank earnings and inflation data loom

U.S. stock futures pointed to a mixed open Monday, with investors looking ahead to a week packed with major bank earnings and key inflation data.

S&P 500 futures were up 0.1%, with Dow Jones Industrial Average futures adding 53 points, or 0.1%, while Nasdaq $NDAQ 100 futures edged down 0.1%. U.S. bond markets are closed Monday for Columbus Day.

Bank of America $BAC, Citigroup $C, Goldman Sachs $GS, JPMorgan $JPM Chase, Morgan Stanley $MS, and Wells Fargo $WFC are all expected to report third-quarter results this week, according to CNBC. September consumer price index data is due Wednesday, followed by the producer price index on Thursday. Federal Reserve Chair Kevin Warsh is also scheduled to appear Thursday at an IMF and World Bank summit in Bangkok, according to The Wall Street Journal.

The S&P 500 is on track to post 29.6% earnings growth for the third quarter, which would mark the fourth consecutive quarter of above-25% growth, according to CNBC, citing FactSet's John Butters. Still, what executives say about the pressure from higher fuel and borrowing costs is likely to draw more investor attention than the reported figures themselves.

"Investors have kind of narrowed in on some of the important aspects," Brian Leonard, portfolio manager of the Keeley Gabelli Small Cap Dividend Fund, told CNBC. "Can this company withstand what's happening? Pass along, continue to grow margins, and the future is going to be better than the most recent past."

The week begins against a backdrop of geopolitical uncertainty. Over the weekend, President Donald Trump declared an "energy ceasefire" between Russia and Ukraine and unveiled a diesel supply arrangement under which Russia would release an initial 300,000 tons of fuel. Ukrainian President Volodymyr Zelenskyy quickly accused Moscow of breaking the ceasefire, and traders largely shrugged off the news, in part because the diesel volume involved — below a single day of U.S. consumption, according to the Journal — was seen as too small to move markets meaningfully. Brent crude was up roughly 1% in early trading, and diesel futures dipped.

Trump separately said he was weighing whether the United States should join Saudi Arabia in operations against Houthi militants backed by Iran following a lethal strike on Riyadh's main airport over the weekend.

Wall Street is coming off a positive week. Both the Dow and S&P 500 ended the week in the green for the second time in three weeks, and the Nasdaq Composite extended its winning streak to four consecutive weeks, lifted by strength in technology shares.

European indexes rose broadly in early trading. South Korea's Kospi fell 3.65% and the Kosdaq dropped 4.83%. Markets in Japan were closed for a holiday.
