Financial markets experienced significant turbulence Monday following weekend U.S. military operations targeting Iran. The immediate reaction saw crude oil surge, equities retreat, and government bond yields climb as traders digested the developing situation.
However, the selloff proved short-lived. Both the S&P 500 and Nasdaq Composite erased opening losses and moved into positive territory before the lunch hour. The Dow Jones Industrial Average similarly recovered from its morning weakness substantially.

Nvidia advanced 2.9% during Monday’s session. Apple contributed a 0.2% increase, propelling the collective Magnificent Seven technology stocks upward by 0.4%.
The iShares Expanded Tech-Software Sector ETF experienced a steep 35% decline from its September high point. The fund has recently rebounded over 7.6% from the previous week’s bottom.
Mislav Matejka from JPMorgan released research advising that investors focused on long-term returns “should be using the weakness” as an entry point for risk-oriented holdings. His analysis emphasized that underlying fundamentals continue to look favorable.
Jonathan Krinsky, BTIG’s leading market technician, gave his analysis the headline “When Missiles Fly, Time to Buy.” He characterized current market conditions as a tactical buying window rather than a moment to reduce holdings.
Adrian Helfert at Westwood observed that maintaining equity positions proved profitable during every similar geopolitical disruption dating back to 1990. Among five comparable crisis events, stock markets delivered positive returns one year later in four instances.
Historical Performance During Geopolitical Crises
Ryan Detrick from Carson Group references research indicating the S&P 500’s median return stands at 2.7% three months following significant market disruptions. The 12-month period shows median gains of 7.4%, with positive performance 65% of the time.
Following the Hamas assault on Israel in October 2023, international equity markets sustained gains throughout the subsequent year. When military operations in Iraq commenced in 2003, stocks delivered approximately 30% returns over the following 12 months.
Veteran market analyst Ed Yardeni expects any elevation in oil prices to prove transitory. His assessment suggests declining fuel costs would enhance consumer spending capacity while pushing inflation metrics toward the Federal Reserve’s 2% objective.
Tigress Financial Intelligence’s Ivan Feinseth indicated the Fed might consider rate reductions should the conflict become prolonged. Such monetary easing would become more probable if Kevin Warsh receives confirmation as Jerome Powell’s successor.
Critical Technical Thresholds for the S&P 500
Tuesday’s futures contracts indicated additional weakness, with Dow futures retreating nearly 800 points. Brent crude oil traded above the $83 per barrel threshold.
The VIX volatility index held above 20, traditionally interpreted as indicating elevated investor apprehension. Year-to-date performance for the S&P 500 stands at a modest 0.5% gain.
Adam Turnquist from LPL Financial cautioned that a decisive move below the 6,775 support level on the S&P 500 could initiate renewed testing of November’s 6,522 low. Technical analysts are monitoring this zone with heightened attention.
