April 2 (Reuters) - U.S. stocks ended slightly mixed on Thursday after paring deeper losses, as diplomatic signals from the Middle East helped calm markets rattled earlier by U.S. President Donald Trump's threats of tougher action against Iran ahead of a long holiday weekend.
Investor sentiment steadied in the afternoon after Iran’s foreign ministry said it was drafting a protocol with Oman to manage traffic through the Strait of Hormuz and Britain said dozens of countries were discussing ways to end the crisis, easing worries about prolonged disruption to global oil flows.
The three indexes had their biggest weekly rise in four months and the first week of gains in six.
Stocks had opened lower amid rising oil prices after U.S. President Donald Trump signaled more aggressive attacks, ahead of the Good Friday holiday, when markets will be closed.
Front-month crude prices surged, with U.S. crude up 11% at around $111 a barrel. The international reference Brent closed up about 7% near $108. But traders priced it at about $82 per barrel in October, a signal that they expect the disruption to be temporary.
“The (stock) market has no real conviction either way right now, but October oil prices tell you the market thinks this crisis will likely be over by the fall,” said Michael Antonelli, market strategist at Baird.

Wall Street's fear gauge, the CBOE VIX index .VIX fell to 23.87 points.
For the week, the S&P 500 gained 3.36%, the Nasdaq rose 4.44%, and the Dow climbed 2.96%. The Russell 2000 small-cap index rose 3.19%.
The rebound reflected caution, with investors favoring stock segments seen as more resilient to economic stress. Utilities, which tend to offer steady earnings and dividends, rose 0.6%. Real estate stocks, which often benefit from steady rental income and tend to perform better when investors seek reliable cash flows in uncertain environments, advanced 1.5%.
Meanwhile, consumer discretionary stocks slid 1.5%, the worst-performing sector on the day, led by a 5.4% drop in Tesla TSLA.O after its first-quarter delivery figures.
Wall Street had opened sharply lower on Iran, in a sharp reversal from Trump's earlier comments that the U.S. will be "out of Iran pretty quickly".
