US stock futures rose but came off gains and oil prices recouped some losses Tuesday after Israel accused Iran of violating a cease-fire that President Donald Trump had announced just a few hours earlier.

These stocks were poised to make moves Tuesday:

Tesla rose 2.7% in premarket trading. The electric-vehicle company jumped 8.2% to $348.71 on Monday following the launch Sunday of its robo-taxi service in Austin, Texas. The gains Monday were the stock's largest since it rose nearly 10% on April 25, according to Dow Jones Market Data, the day the Transportation Department announced a new framework for self-driving cars.

Super Micro Computer was up 3.6% after tumbling 9.8% on Monday following an announcement the server maker planned a $2 billion senior convertible notes offering. Super Micro ended Monday's session as the worst performer in the S&P 500. It snapped a two-day winning streak but has risen 34% this year.

Occidental Petroleum fell 1.8% and Exxon Mobil was down 1.5% as the stocks followed oil prices lower.

RTX was falling 1.6%, Lockheed Martin declined 1.6%, and other defense companies traded lower after the cease-fire between Israel and Iran was announced.

KB Home was down 0.4%. The home builder reduced its fiscal-year outlook after posting second-quarter earnings and revenue that fell from a year earlier. Home deliveries during the period fell 11%. KB Home expects housing revenue of $6.3 billion to $6.5 billion in the current fiscal year, down from prior guidance of $6.6 billion to $7 billion.

Earnings reports are expected Tuesday from FedEx, Carnival, TD Synnex, AeroVironment, BlackBerry, and Worthington Enterprises.

FedEx was up 1% in premarket trading ahead of fiscal fourth-quarter earnings from the shipping giant. FedEx will issue its report after the stock market closes Tuesday. Wall Street anticipates FedEx will report earnings of $5.87 a share on revenue of $21.8 billion.

Shares of cruise operator Carnival rose 1.8% in the premarket session. The company likely will address disruption in the Middle East and the impact of rising fuel prices when it issues second-quarter earnings before the opening bell. Analysts expect Carnival to report earnings of 25 cents a share on sales of $6.21 billion.
