S&P 500 Surges 2.91% on Iran Peace Hopes

U.S. markets closed strongly on March 31, 2026, with the S&P 500 surging 2.91% to 5,611.85 and the Dow Jones Industrial Average gaining over 1,000 points. The Nasdaq Composite jumped 3.83%, led by a tech stock recovery. However, for Q1 as a whole, the S&P 500 declined 4.37%, marking its worst quarterly performance since 2022. A rebalancing calculator can help investors assess their portfolio adjustments heading into Q2.
Iran Peace Hopes Sparked the Rally
The direct catalyst was President Trump's public expression of willingness to end the war with Iran. Iran's president also signaled readiness for peace, triggering a wave of relief buying. The VIX volatility index plunged 17.51% in a single day, and safe-haven sentiment rapidly retreated. Investors should use an asset allocation calculator to review equity weightings during such geopolitical shifts.
Q1 Report Card: Worst Since 2022
Despite the day's rebound, SPY fell 4.37% year-to-date while QQQ dropped 5.93%. The combination of surging energy prices from the Iran conflict, inflation concerns, and the Fed's prolonged rate hold all contributed. VOO also declined 4.42%, showing broad weakness across S&P 500 tracking ETFs. TQQQ, the 3x leveraged Nasdaq ETF, suffered a 20.81% YTD decline despite its 10% daily gain.
Diverging Sector Performance
Energy was the only major sector posting positive returns in Q1, with XLE surging 37.91%. Meanwhile, growth-oriented tech ETFs like QQQ fell approximately 6%. The semiconductor sector showed resilience with SMH gaining 6.46%, proving the staying power of the AI investment theme. However, elevated valuations among mega-cap tech stocks continued to weigh on investor sentiment.
Expert Q2 Outlook
Wall Street analysts suggest that if Iran ceasefire negotiations progress substantively, falling oil prices could ease inflation pressures and increase the probability of Fed rate cuts. However, some analysts cautioned that the correction may not be fully over, recommending a measured approach. SPY remains 6.8% below its 52-week high of $697.84, suggesting room for recovery or further consolidation.
Action Points for ETF Investors
Whether this rally represents a dead-cat bounce or genuine trend reversal depends on Iran negotiation progress. AGG ETF rose modestly at 0.23%, reflecting the bond market's cautious stance. Investors should use a rebalancing calculator to check portfolio drift from target allocations and review their asset allocation strategy as Q2 begins. TLT vs IEF comparison remains crucial for fixed-income positioning.
Conclusion
The strong end-of-March rally demonstrated that markets remain sensitive to positive geopolitical developments. However, Q1's overall performance serves as a reminder of how significantly geopolitical risks and macro uncertainty can impact returns. As Q2 begins, investors should conduct thorough portfolio rebalancing to reassess the balance between risk assets and safe havens.
