Overview:
The S&P 500 opened Friday's session at 6,783.69, pulling back from Thursday's close of 6,824.66 as the March CPI print — the first of the Iran-war era — came in at 3.3% year-on-year, the largest annual gain since 2022. TSMC (TSM) was the dominant catalyst-driven mover at the opening bell, with shares rising roughly 2.31% on the back of record Q1 revenue of $35.71 billion, beating the LSEG SmartEstimate of $35.26 billion and printing a 35% year-on-year gain. Oil remained a destabilising macro for
NEW YORK, April 10, 2026 — U.S. equities opened Friday’s session on a cautious note, with the S&P 500 printing an opening level of 6,783.69 — down from Thursday’s close of 6,824.66 — as investors processed a hotter-than-expected March consumer price index report, persistent uncertainty over the fragile U.S.-Iran ceasefire, and the commencement of Islamabad peace talks that carry outsized consequences for energy markets. The Nasdaq Composite and Dow Jones Industrial Average tracked similarly subdued openings, though the session’s dominant single-stock story arrived with clarity: Taiwan Semiconductor Manufacturing Company (NYSE: TSM) surged at the bell on the back of a record-breaking first-quarter revenue report that reinforced the durability of AI-related chip demand even through weeks of geopolitical turbulence.
Market open snapshot: indices, macro, and the CPI overhang
The opening price for the S&P 500 today was 6,783.69. That represented a softening from Thursday’s close, when the S&P 500 added 0.62% to end at 6,824.66, while the Nasdaq Composite climbed 0.83% to 22,822.42. The Dow Jones Industrial Average rose 275.88 points, or 0.58%, to settle at 48,185.80, with the 30-stock index turning positive for the year, up 0.25%. Thursday’s gains had been the seventh consecutive winning session for the S&P 500, extending a ceasefire-relief rally that began Tuesday night.
Friday’s tone was shaped almost immediately by the 8:30 a.m. ET release of the Bureau of Labor Statistics’ March CPI report — the first inflation print of the Iran-war era. The release showed annual headline CPI soared in March to 3.3%, for the largest monthly gain since 2022. The rapid acceleration from February’s inflation level of 2.6% came as the U.S.-Iran war sent gas prices skyrocketing. The print landed broadly in line with the upper end of the consensus range. For more on the inflation backdrop, see our dedicated analysis: March CPI, April 10, 2026: the first inflation print of the Iran war era.
Ahead of the open, contracts on the S&P 500 and on the Nasdaq 100 both rose 0.2%, on the heels of a seventh winning day in a row. However, those muted futures gains gave way to modest pressure once the CPI data was absorbed. Investors are now focused on the Iran-U.S. talks slated to occur this weekend, looking for signs the fragile two-week truce might lead to a longer-lasting plan for peace. Ahead of the meeting, President Trump ramped up pressure on Iran to lift its blockade of the Strait of Hormuz, with little sign of success. Traffic through the world’s most critical chokepoint for energy supply is still thin.
The FOMC dimension added another layer of complexity. As detailed in our earlier coverage, FOMC minutes from April 9, 2026, showed that rate hikes are back on the table as the vast majority of Fed officials warned inflation is running persistently above target. While forecasts call for a hot March inflation report, economists almost unanimously agree that the Fed will not pursue an interest rate cut at its April 29 meeting.
Opening bell standout mover: Taiwan Semiconductor Manufacturing (TSM)
The session’s clearest catalyst-driven mover was Taiwan Semiconductor Manufacturing Company (NYSE: TSM), the world’s largest contract chipmaker. TSMC reported on Friday first-quarter revenue of T$1.134 trillion ($35.71 billion), beating the market forecasts and up 35% on the year-ago period on surging interest in artificial intelligence applications. An LSEG SmartEstimate, drawn from 20 analysts, had predicted first-quarter revenue of T$1.125 trillion.
TSMC’s U.S.-listed stock rose more than 2% in pre-market trading after the report. Specifically, as of 8:30 a.m. ET, TSM was trading at $373.95 in the pre-market session, up $8.46 or 2.31% from the previous market close of $365.49. The move placed TSM well above its prior session close as investors rewarded the chipmaker for demonstrating resilience in its order book even as the Iran-war energy shock created macro headwinds throughout the quarter.
The growth is not only impressive on a year-over-year basis but also reflects a strong sequential rise of 30.7%, showcasing the company’s agility in responding to market demands. Revenue for the month of March alone reached 415.2 billion new Taiwan dollars, reflecting a 45.2% jump compared with the same month a year earlier, according to CNBC. Orders flowing from major clients including Apple and Nvidia have underpinned the strong performance, though questions remain over how prolonged Middle East instability could affect logistics and future purchasing.
The monthly revenue disclosure is a precursor to full quarterly earnings. Investors await the company’s full Q1 earnings announcement scheduled for April 16, 2026. That call, scheduled to include margin data, will be closely watched for guidance on how supply chain conditions near the Strait of Hormuz may affect TSMC’s cost structure in Q2.

Volume and price action analysis
TSM: above-average volume anticipated on revenue catalyst
TSM’s pre-market move of 2.31% on a high-conviction fundamental catalyst — the strongest quarterly revenue beat in recent sessions — set up conditions for elevated volume at the opening bell. The average daily trading volume for Taiwan Semiconductor is 6,156,231 shares. Revenue beats of this magnitude, particularly those tied to an ongoing AI demand supercycle narrative that has sustained multi-quarter momentum, historically attract institutional rotation into the name in the first hour. A record-breaking first quarter saw TSMC generate 1.13 trillion new Taiwan dollars ($35.6 billion) in revenue, topping the analyst consensus. The figures suggest AI chip orders stayed resilient through the Iran war’s opening weeks, with the conflict’s onset coinciding with the quarter’s early stretch.
Broader market: mixed session with geopolitical and inflation cross-currents
Beyond TSM, the broader tape at the opening bell reflected a market navigating compressed risk appetite. Stock futures were mixed Friday morning as the initial U.S.-Iran ceasefire relief rally faded, with doubts over its durability compounded by continued regional friction and minimal improvement in Strait of Hormuz tanker traffic, reintroducing a risk premium pushing oil back toward the $100 mark.
Crude oil dynamics remained a primary overhang for both energy and consumer discretionary names. Oil prices were off their highs on Friday amid persistent tensions around the Strait of Hormuz, with the vital shipping lane still largely closed despite the ceasefire deal between the U.S. and Iran. U.S. West Texas Intermediate crude futures for May delivery gained 0.6% to $98.46 per barrel at around 7:20 a.m. ET, after passing $100 earlier in the session. International benchmark Brent crude futures for June delivery were up 0.42% at $96.36 per barrel.
The energy sector’s dynamics were further complicated by infrastructure damage. Iranian strikes hit a pumping station along Saudi Arabia’s East-West pipeline, which transports crude from processing facilities near the Persian Gulf to the Red Sea export terminal at Yanbu. Riyadh has leaned heavily on the pipeline as its primary export route during the conflict, as Iranian attacks have made shipments through the Strait of Hormuz increasingly unviable.
The S&P 500 has broken through the 100-day moving average near 6,800, firmly back inside the 6,700–7,000 range the index sat in for most of the past six months, with the index recently up over 0.5% on Thursday. The index’s positioning relative to key technical levels remained a focal point for desk commentary at the open.

Simulations Plus (SLP): earnings beat tempered by guidance cut
Among the secondary movers at Friday’s open was Simulations Plus (Nasdaq: SLP), the biosimulation software company that reported Q2 fiscal 2026 earnings after Thursday’s close. Simulations Plus posted Q2 2026 revenue of $24.3 million, up 8%, with EPS rising to $0.22 and adjusted EBITDA margin at 36%. The company achieved an adjusted earnings per share of $0.35, exceeding the forecasted $0.31, marking a 12.9% surprise, while revenue surpassed expectations by 12.19%. However, the headline beat was offset by a guidance revision: adjusted diluted EPS guidance was reduced from $1.03–$1.10 to $0.75–$0.85, reflecting a higher expected effective tax rate of 23–25% versus 12–14%, which lowers anticipated fiscal 2026 earnings. The guidance cut introduced a notable complication for investors pricing in a clean beat-and-raise narrative, and the stock’s reaction at the opening bell reflected that offsetting dynamic.
What to watch in the first hour
Islamabad talks: the single most consequential event for energy pricing
The Islamabad peace negotiations between U.S. and Iranian delegations — scheduled to commence Friday under Pakistani mediation — represented the most significant macro catalyst for the first trading hour. The Islamabad peace talks began April 10, with both sides working from different frameworks: Iran brought a 10-point plan, the U.S. has a 15-point plan. The gap between these positions will determine whether the ceasefire extends or collapses. Any headline suggesting forward progress on the Strait of Hormuz reopening had the potential to put immediate downward pressure on WTI crude and provide relief to airline, consumer discretionary, and logistics names. Conversely, a breakdown in talks — or a fresh Iranian assertion of blockade authority — carried the risk of sending oil back above $100 with knock-on effects for the broader tape.
Adrian Beciri, CEO of DUCAT Maritime, a Cyprus-based logistics firm specialising in dry bulk, stated that the Strait of Hormuz remains effectively closed and that the behavioural attitudes of shipowners and operators are exactly the same as at the peak of the conflict. “Quite frankly speaking, the situation is extremely chaotic. There is no known or established way to transit the Straits of Hormuz. There is even not a clear way to contact the Iranians on how to do it, which seems to be the only way at the moment,” Beciri told CNBC.
TSMC print and semiconductor sector sentiment
TSM’s revenue beat provided a tailwind not just for the stock itself but for the broader semiconductor complex in early trading. TSMC, the world’s largest contract chipmaker, posted a 35% surge in first quarter revenue on Friday, beating Wall Street forecasts thanks to unabated interest in AI applications. Shares of the Taiwanese supplier to Nvidia rose 2% in pre-market trading on Wall Street. Traders were monitoring whether the move in TSM would spill over into Nvidia (NVDA), Broadcom (AVGO), and ASML (ASML) in the first 30 minutes of trade — names that had already rallied meaningfully on ceasefire relief earlier in the week. For reference, the opening bell on April 8, 2026 saw the S&P 500 surge ~2.5% on ceasefire euphoria — a magnitude of move the current session was not tracking to replicate given the CPI overhang.
Upcoming earnings: Q1 season opens next week
Friday’s session also served as a practical staging point ahead of the formal launch of large-cap Q1 earnings season. Goldman Sachs (GS) is expected to report on April 13, while April 14 brings JPMorgan Chase (JPM), Johnson & Johnson (JNJ), Wells Fargo (WFC), Citigroup (C), and BlackRock (BLK). Financials in particular face a complex backdrop: the combination of elevated interest rates, persistent inflation, and a nascent but fragile ceasefire creates an unusually wide range of outcomes for net interest income guidance. CNBC’s banking coverage has tracked the sector’s elevated sensitivity to macro crosscurrents throughout the Iran-war period.
University of Michigan consumer sentiment
Beyond CPI, Friday’s 10:00 a.m. ET release of the preliminary April University of Michigan Consumer Sentiment survey represented an additional data point for the first-hour tape. The April 10 calendar also included the preliminary April University of Michigan Consumer Sentiment reading alongside the March CPI figures. A sharp deterioration in sentiment — particularly in the inflation expectations sub-component — carried the potential to reinforce the hawkish read of the morning’s CPI print and weigh on rate-sensitive sectors.
Conclusion: navigating a high-complexity first hour
Friday’s opening bell presented participants with an unusually dense information environment: a first-of-cycle CPI print confirming the Iran war’s inflationary transmission, a landmark TSMC revenue beat reaffirming AI demand durability, crude oil stubbornly holding near $98 despite a nominal ceasefire, and the geopolitically pivotal Islamabad talks beginning in real time. The S&P 500 and Nasdaq both remained about a tenth of a percentage point away from erasing this year’s losses as of early trading, underscoring how much ground had been recovered in a compressed seven-session rally — and how much remained contingent on events unfolding far beyond the trading floor. The first hour of trade would test whether TSM’s AI-driven momentum could provide durable ballast against the macro headwinds still emanating from the Persian Gulf.
