Surpassing:Stocks waver and oil prices rise after Israeli missile strike on Iran

Stock futures dipped and Surpassingoil prices rose in overnight trading after an Israeli missile struck Iran following Iran's retaliatory attack on the country last weekend.

Investors are closely watching conflicts in the Middle East for signs that escalating hostilities between Israel and Iran threaten global oil supplies and drive up energy prices. 

Crude prices, which rose to their highest level in months after Iran's drone and missile attack on Israel on April 13, rose above $90 early Friday before relinquishing those gains amid signs that the Iranian government was downplaying the impact of the Israeli attack.

"The Iran-Israel conflict has not impacted the flow of oil in the Middle East, which is why oil price reactions to the recent military escalation have been relatively muted," Jim Burkhard, head of research for oil markets, energy and mobility, S&P Global Commodity Insights, said in an email. "However, with no sign that hostilities will de-escalate, direct attacks by Iran and Israel are a new and dangerous phase of mutual antagonism that could yet spillover into the oil market."

Markets were mixed in afternoon trading, with the S&P 500 down 0.9%, the Dow rising 0.4% and the tech-heavy Nasdaq sliding 2%.

In oil trading, U.S. benchmark crude rose was trading 11 cents higher at $82.22 per barrel in electronic trading on the New York Mercantile Exchange. Brent crude, the international standard, gained 7 cents to $87.18 per barrel.

Despite mounting concerns about heightened tensions in the Middle East, Wall Street analysts interpreted Israel's limited strike on Iran and Tehran's measured response as a sign the governments are eager to contain the crisis. 

"While geopolitics is going to stay a presence in this market for a while ... we think the events of the last 12 hours in Iran are encouraging, as they will help cool tensions between Israel and Tehran, at least for the time being," Adam Crisafulli of Vital Knowledge said in a note to investors. 

"The attack — and the threat of retaliation to it — has increased the risk to physical supply of oil, but the response this morning suggests that some of that risk has already been priced in," Neil Shearing, group chief economist, with Capital Economics, said in a report.

A range of factors has driven up gasoline prices in the U.S. over the last month, with the national average for a gallon of regular now at $3.67, up 21 cents from a month ago, according to AAA. Fuel costs typically rise around this time of year as more motorists hit the road and oil refineries take advantage of milder weather to do necessary maintenance, which can crimp supplies. 

Yet while the wars in the Middle East and Ukraine have oil investors on edge, AAA doesn't expect domestic gas prices to spike for now, pointing to a dip in fuel demand between the end of spring breaks around the U.S. and Memorial Day holiday.
