U.S. stocks pulled back on Tuesday, March 24, surrendering a portion of Monday’s sharp relief rally gains as oil prices surged back above $100 per barrel and confusion grew over the status of U.S.-Iran peace talks. Meanwhile, European stocks closed marginally higher in a choppy session, with oil and gas stocks leading gains across the continent.

What Moved Markets: Iran Negotiations in Focus

Stocks opened sharply lower — the Dow shed 385 points and the S&P 500 and Nasdaq each dropped 0.7% at the open — as investors grew skeptical about the credibility of U.S.-Iran de-escalation talks. Markets had staged a powerful relief rally on Monday after President Trump wrote on Truth Social that the two sides had held “very good and productive conversations” about a resolution to the Middle East conflict.

However, Iranian state media denied any direct talks had taken place, and Israel and Iran continued to exchange strikes throughout Tuesday. The Pentagon is also reportedly planning to deploy around 3,000 soldiers to the Middle East, though no final decision on ground forces has been made.

In a pivotal development after the close, The New York Times reported that the U.S. has sent Iran a 15-point peace plan to end the war, delivered through Pakistan. The report lifted stock futures sharply in after-hours trading — Dow futures jumped 320 points (+0.7%), S&P 500 futures rose 0.7%, and Nasdaq 100 futures climbed 0.9%.

Adding to the geopolitical drama, Pakistani Prime Minister Shehbaz Sharif offered to host peace talks between Washington and Tehran. Meanwhile, The Wall Street Journal reported that Saudi Arabia and the UAE are moving closer to joining the fight against Iran — Saudi Crown Prince Mohammed bin Salman is reportedly close to a decision to participate.

Michael Kantrowitz, chief investment strategist at Piper Sandler, described the current environment as “just an oil-driven, one-variable market.”

“Oil and interest rates are driving the equity market. The U.S. economy can certainly handle $90, $100 oil. I’m a little more concerned about interest rates and the fear of persistent inflation weighing on equity multiples.”

— Michael Kantrowitz, Piper Sandler, on CNBC’s Closing Bell: Overtime

Six energy stocks hit all-time highs during Tuesday’s session, underscoring the sector’s dominance:

Energy was the S&P 500’s top-performing sector for the session (+2%) and the only sector in positive territory month-to-date, with gains exceeding 9% in March.

Private Credit Stress: Apollo & KKR in the Spotlight

Signs of strain in the private credit market continued to emerge:

  • FS KKR Capital (FSK) −3.3%Moody’s downgraded the private credit fund to junk (Ba1 from Baa3), citing worsening asset quality and non-accrual loans rising to 5.5% of total investments.

DoubleLine Capital CEO Jeffrey Gundlach described the current environment as a “going nowhere” market, noting “almost nothing is up” and “nothing has really made much money over the past nine months.”

Retail Investor Sentiment: First Net Selling Since 2023

Monday marked an “inflection point” for retail investors, according to VandaTrack. Everyday traders sold more than $20 million worth of single stocks on balance — the first day of net selling since November 2023. The trend reflects gradually receding retail participation since the start of the U.S.-Iran conflict, alongside systematic deleveraging.
