U.S. equities hit new highs following a report from Axios, citing a regional source and two U.S. officials, stating that Iranian and U.S. negotiators have reached a 60-day memorandum of understanding. This agreement aims to prolong the ceasefire and facilitate additional discussions regarding Iran’s nuclear capabilities. The report noted, however, that the deal is still awaiting final authorization from President Donald Trump.

“The market has been expecting some type of MOU — memorandum of understanding — here,” said David Wagner, head of equities at Aptus Capital Advisors told CNBC in an interview. “You’re going to see the discretionary names run as a first knee-jerk reaction to a lot of this news, which can drive the market higher.” 

However, Treasury Secretary Scott Bessent said on Thursday that no Iranian sanctions would be lifted unless the country gives up its enriched uranium stockpile. 

Oil prices pulled back from their highs following the report. The West Texas Intermediate crude oil futures was last trading at around $89 a barrel, while Brent futures traded around $94 a barrel, as per data from CNBC. 

Moreover, the Personal Consumption Expenditures (PCE) Index, which is the Federal Reserve’s preferred gauge of inflation, advanced 3.8% in April on an annualized basis.

The Commerce Department data showed that core PCE, which excludes food and energy, rose 3.3% on an annualized basis in April, up 0.2% on a monthly basis.
