US stock futures slipped Sunday evening as investors turned their focus to a packed slate of earnings and eyed the ongoing war between the US and Iran.

Futures tied to the Dow Jones Industrial Average (YM=F) slipped about 100 points, or 0.2%, while contracts linked to the S&P 500 (ES=F) and Nasdaq 100 (NQ=F) traded little changed.

Oil prices climbed at the open as geopolitical concerns continued to drive energy markets higher. West Texas Intermediate (CL=F) crude gained 1.8% to trade above $107 a barrel, while Brent (BZ=F) crude added roughly 1.1% to top $110.

The change to commodities arrived as equities hover near record territory after the S&P 500 (^GSPC) and Nasdaq Composite (^IXIC) notched fresh highs last week and the Dow (^DJI) briefly crossed the 50,000 mark. The Nasdaq 100 tumbled 1.5%, marking its steepest one-day decline since late March.

Investors also remained attentive to developments in the Iran-US conflict. President Donald Trump said Sunday that “the clock is ticking” for an agreement or there “won’t be anything left,” even as negotiations between the two countries continued.

Markets are bracing for several closely watched corporate reports this week. Nvidia (NVDA) is scheduled to release quarterly earnings on Wednesday alongside Target (TGT), with Walmart (WMT) set to follow on Thursday.

Meanwhile, hotter-than-expected inflation readings released last week further dampened hopes that the Federal Reserve could begin lowering interest rates in the near future.
