[BRIEFING.COM] The stock market continued its strong start to the week as a sharp retreat in oil prices created a favorable backdrop for equities, while mega-cap stocks provided an additional boost by extending yesterday's rally. The S&P 500 (+1.2%), Nasdaq Composite (+2.0%), and DJIA (+0.7%) posted gains that were nearly identical to yesterday's advance, with the major averages now all in positive year-to-date territory.
Lingering optimism around a more permanent ceasefire continues to support the market's sharp rebound over the past several weeks. President Trump told The New York Post that in-person negotiations between the U.S. and Iran could occur within the next two days.
So far, the temporary ceasefire and the U.S. blockade of Iranian ports are holding. Crude oil futures settled today's session $7.66 lower (-7.7%) at $91.31 per barrel.
Today's advance was supported by broad-based strength, with all but the energy (-2.2%), materials (-0.3%), and consumer staples (-0.2%) sectors finishing higher.
Growth-oriented areas led the way, with communication services (+3.2%) and consumer discretionary (+2.5%) sectors posting outsized gains behind continued mega-cap leadership. Meta Platforms (META 662.46, +27.92, +4.40%) was a "magnificent seven" standout, while Amazon (AMZN 248.97, +9.08, +3.79%) traded higher after reports that the company is set to acquire Globalstar (GSAT 79.91, +7.02, +9.63%).
NVIDIA (NVDA 196.46, +7.15, +3.78%) captured a similar gain, and the information technology sector (+1.7%) also finished near the top of today's leaderboard. Micron (MU 465.66, +39.10, +9.17%) was one of the best-performing S&P 500 names today, and the PHLX Semiconductor Index (+2.0%) steadily charted session highs throughout the session.
All told, the Vanguard Mega Cap Growth ETF finished 2.0% higher, helping the market-weighted S&P 500 (+1.2%) outperform the S&P 500 Equal Weighted Index (+0.4%).
Elsewhere, investors had plenty of earnings and corporate news items of note today. The financials sector (+0.2%) captured a modest gain as the market had mixed reactions to the earnings reports of several major banking names. Citigroup (C 129.65, +3.37, +2.67%) was a standout after topping earnings expectations and issuing upside Net Interest Income guidance, while JPMorgan Chase (JPM 311.12, -2.56, -0.82%) also beat expectations but issued a modest downward revision to its FY2026 net interest income.
Meanwhile, Wells Fargo (WFC 81.73, -4.91, -5.67%) was one of the worst-performing S&P 500 components after narrowly topping EPS estimates but missing on revenues.
Airlines also had an eventful session after Bloomberg reported that United Airlines (UAL 97.17, +1.97, +2.07%) floated the possibility of a merger with American Airlines (AAL 12.13, +0.90, +8.01%).
Outside of the S&P 500, the Russell 2000 (+1.4%) captured another solid gain as the market leans into a risk-on tone, while the S&P Mid Cap 400 (+0.5%) finished with a more modest gain.
After two solid days of broad strength, the major averages are back into positive territory for the year as the market shakes off losses tied to the war in Iran. This morning's release of the March PPI report added further support to the rebound narrative, with both the headline (0.5%; Briefing.com consensus 1.2%) and core (0.1%; Briefing.com consensus 0.4%) readings coming in cooler-than-expected.
While there has yet to be a conclusive end to the conflict, the market remains confident that disruptions across global oil markets will pressure Iran into a more durable ceasefire agreement sooner rather than later.
Overall, the tone remains constructive as falling oil prices, easing inflation pressures, and renewed mega-cap leadership continue to support the market's advance. With Q1 earnings season beginning to ramp up, strength in mega-cap names is once again playing an outsized role in driving index performance, leaving the S&P 500 just 0.5% below its all-time high and within striking distance of record territory.
U.S. Treasuries had a solid outing on Tuesday, making for a continuation of an upbeat start to the week amid a growing sense that the Iran conflict will conclude soon. The 2-year note yield settled down three basis points to 3.75%, and the 10-year note yield settled down four basis points to 4.26%.
