Stocks Slide to Weekly Losses as Oil, Yields, and Geopolitics Weigh on Sentiment

U.S. equities closed out a difficult week on a weak note, with persistent pressure from rising oil prices and Treasury yields pushing the major indices decisively lower. The S&P 500 fell 1.5%, the Nasdaq Composite dropped 2.0%, and the Dow Jones Industrial Average declined 1.0%, leaving all three benchmarks firmly below their 200-day moving averages.

The S&P 500 managed to hold just above the psychologically important 6,500 level, closing at 6,506 and narrowly avoiding its first break below that threshold since early September. Still, the broader technical picture continues to deteriorate as downside momentum builds.

The drivers behind today’s weakness were largely unchanged from recent sessions. Crude oil resumed its upward climb, settling at $98.12 per barrel, as geopolitical tensions in the Middle East intensified. Earlier optimism that the conflict with Iran might de-escalate faded quickly after fresh reports indicated a deeper U.S. military involvement. According to multiple outlets, the Pentagon is deploying additional warships and troops to the region, with contingency plans that could include ground operations.

That escalation has reinforced concerns about prolonged disruptions to global energy supply, keeping upward pressure on oil prices. In turn, inflation expectations are rising again, complicating the Federal Reserve’s policy outlook. Market pricing now reflects a growing risk of tighter policy, with the probability of a rate hike by the December FOMC meeting climbing to roughly 25%, according to CME FedWatch data.

Against this backdrop, selling was broad and indiscriminate. Nearly every sector finished lower, highlighting a clear “risk-off” tone.

Rate-sensitive sectors bore the brunt of the pressure. Utilities plunged 4.1%, with sharp declines in names such as Vistra Corp. and Constellation Energy, both of which suffered double-digit losses. Real estate followed with a 3.2% drop as Treasury yields surged, with the 10-year note climbing 11 basis points to 4.39%.

Growth-oriented sectors also struggled under the weight of higher rates. Information technology fell 2.2%, while consumer discretionary and communication services declined 1.9% and 1.5%, respectively. Mega-cap weakness remained a key drag, with the broader growth complex underperforming.

Within tech, Super Micro Computer stood out on the downside, plunging more than 30% after reports that employees were charged with illegally exporting chips to China.

Interestingly, the energy sector failed to capitalize on higher oil prices, finishing flat after giving back earlier gains—a sign of fading momentum even in one of the year’s strongest groups.

The lone bright spot came from financials, which eked out a modest 0.2% gain. Strength in major banks and insurance companies, including Marsh McLennan and Aon, helped offset continued weakness among asset managers.

Outside the large-cap space, risk appetite deteriorated further. The Russell 2000 and S&P MidCap 400 dropped 2.3% and 2.2%, respectively, underperforming the major indices as investors moved away from higher-beta segments of the market.

Overall, the week’s price action underscores a market increasingly constrained by a confluence of macro headwinds: surging energy prices, rising yields, and escalating geopolitical risks. With key technical levels now broken and policy uncertainty rising, sentiment has turned more cautious as investors reassess both the inflation trajectory and the Federal Reserve’s next move.

Our FTinvest 11 model portfolio dropped sharply by 3.07% to close at 918.52, marking the steepest single-day decline in recent months. The portfolio has now fallen 11.64% from its all-time high of 1,039.51, officially entering correction territory. The move reflects intensified selling pressure and a continuation of the broader downward trend observed throughout March.

Year-to-date, FTinvest 11 is now down 1.04%, fully erasing its earlier gains for 2026. However, the portfolio still outperforms the S&P 500, which is down 4.95% YTD, highlighting relative strength despite the recent drawdown. While short-term momentum has clearly weakened, the portfolio’s long-term, value-driven discipline remains intact as it navigates a more challenging market environment.
