To correct the reference to Hezbollah in paragraph 8

NEW YORK, June 4 (Reuters) - Wall Street stocks rose on Thursday, with investor sentiment improved by progress toward ending the Iran war, while disappointing Broadcom results limited gains in the Nasdaq index due to a sell-off in chip stocks.

The Dow Jones index of leading stocks rose, recording its highest closing level, supported by healthcare and financial sector stocks.

The Standard & Poor's 500 index posted modest gains, while the Nasdaq index ended the session virtually unchanged.

Chipmaker Broadcom failed to meet revenue expectations, sending its stock tumbling and raising doubts about the momentum of the artificial intelligence boom that has strongly supported the sector's stocks since the start of the year.

Paul Nolte, senior wealth advisor and market analyst at Murphy & Silvest in Illinois, said, "The only real downside to the market right now is Broadcom, and I think investors are buying when prices are low."

The US House of Representatives on Wednesday passed a measure aimed at preventing US President Donald Trump from continuing the war on Iran.

The ceasefire agreement, brokered by the United States between Israel and Lebanon, has boosted optimism for a near-term resolution to the war, as the agreement is a prerequisite for Iran's acceptance of peace.

But the Iranian-backed Lebanese group Hezbollah rejected the truce.

The decline in oil futures for the nearest month's delivery has boosted hopes that oil tanker traffic through the vital Strait of Hormuz will resume soon.

According to preliminary data, the S&P 500 closed up 31.14 points, or 0.41 percent, at 7,584.82. The Nasdaq Composite fell 19.72 points, or 0.07 percent, to 26,834.26. The Dow Jones Industrial Average gained 875.09 points, or 1.73 percent, to 51,562.16.
