Saturday's attack on Riyadh's airport brings oil and transportation costs back into focus for the coming week. The broader stock market rose last week while chip stocks fell. The next inflation reports will help test whether that divergence can persist.

For companies, the challenge goes beyond selling more. Higher energy costs can reduce the profit earned on the same sales, while persistent inflation can keep borrowing expensive. Long-term expectations for artificial intelligence do not remove either cost in the short run.

Key takeaways

  • An airport attack does not directly establish a loss of oil production. But regional tensions could affect oil flows, shipping routes or insurance costs, changing companies' expenses. I will watch for concrete evidence of that connection in the coming week.
  • Friday's rebound is hard to interpret as strength across the entire technology sector. Chip stocks diverged sharply from the broader market over the week; which stocks contribute to an index's gains still matters.
  • Weak consumer sentiment and high energy costs can squeeze companies from both directions: production becomes more expensive, and customers have less money to spend. During earnings season, margins and cash generation deserve attention alongside revenue growth.

What happened this week?

  • Comparing daily closing values for October 2 and October 9, SPY, which tracks the S&P 500, rose approximately 1.16%, and Nasdaq 100 tracker QQQ ($QQQ) gained 0.23%. Chip-stock ETF SMH ($SMH) fell 4.32%. Such different results in the same week show that long-term optimism about technology and near-term buying interest are different things.
  • The University of Michigan's preliminary October consumer sentiment index fell to 46.3 from September's 48.1. The survey describes how people view economic conditions; it does not prove that spending fell by the same proportion. It nevertheless creates a more cautious backdrop for companies' sales expectations.
  • On October 9, Delta gave a full-year adjusted earnings-per-share outlook of $5.10-$5.60. Its July range on the same basis was $6.50-$7.50. The change is a concrete example of why passenger demand alone does not always deliver strong earnings when fuel costs are high.
  • A U.S. Treasury authorization dated October 9 permits specified transactions involving the sale and delivery of Russian-origin diesel. Permission does not establish that the fuel has reached buyers or that prices have fallen. Any actual increase in supply needs to be monitored separately.
  • Reuters, citing Saudi civil aviation authorities, reported 12 deaths and 309 injuries in Saturday's Riyadh attack. The Saudi-led coalition blamed the Houthis. The attack alone does not establish a reduction in oil production.
  • Expectations for AI-company IPOs are also in focus. Anthropic's official announcement says it confidentially submitted a draft registration statement on June 1; the number of shares and price range have not been determined. A potential IPO valuation should not be treated as the company's established current value when discussing its growth prospects.

What changed since the start of the week?

  • At the start of the week, we were watching the Nasdaq's record and buying that continued despite high interest rates. By the weekend, losses in chip stocks, weak consumer sentiment and renewed regional tensions stood out together. The question now extends beyond rising indexes to whether companies can meet expectations in this cost environment.

Market levels

U.S. indexes and chips

  • QQQ ended Friday at $751.27. The session's $748.37 low and $752.87 high provide an initial monitoring range. A break above the upper boundary could support continued buying; losing the lower boundary would weaken Friday's rebound. These are one-session limits, not established support and resistance levels.
  • SMH, at $603.33, remained close to Friday's $601.38 low. That low is an initial support candidate; the $615.55 intraday high could form resistance above. Buying that holds into the close would be more meaningful here than an upbeat opening alone.

Bonds and precious metals

  • TLT, which tracks long-term U.S. Treasuries, was at $77.98; Friday's $77.49 low is a support candidate, and the $78.05 high is a near-term resistance candidate. A move toward the upper boundary could be consistent with stronger demand for bonds. This fund price should not be read as a Treasury yield.
  • Gold-tracking GLD ($GLD) ended the week at $384.58. Buyers holding Friday's $383.26 low could strengthen the formation of support. Above, $385.17 is the first resistance candidate; if it is crossed, I will watch whether the move holds.
  • Silver ETF SLV ($SLV) was at $54.78, just above its $54.75 daily low. Losing that support candidate would weaken the rebound; a move toward the resistance candidate near $55.25 could suggest stronger buying. These two fund prices are not the metals' prices per ounce.

Crypto

  • Bitcoin was approximately $82,961 around 9:11 a.m. on Sunday. In financial analyst Tunç Şatıroğlu's (@tuncsatiroglu) analysis, $83,400 is a conditional threshold that needs to be crossed for a recovery. Below, the first $82,300 area can be monitored for potential support; I am not rushing to treat brief weekend moves as a lasting reversal.
  • Ethereum was approximately $2,502 around 9:08 a.m. that morning. It remains below Şatıroğlu's $2,530 recovery threshold. If that resistance cannot be regained, his analysis leaves the risk of a retest of $2,350 in play. The current bounce does not yet prove that strong support has formed.

Red flags

  • Regional tensions that cause persistent transportation or production disruptions could make disinflation harder. In that situation, I would not expect energy producers and fuel-consuming companies to move in the same direction.
  • Falling margins and cash flow despite strong sales growth could reveal weakness beneath an earnings headline. That distinction is especially important for technology companies with high capital spending.

Calendar

  • Monday, October 12: A regular U.S. equity session is scheduled, while the bond market has a holiday. Trading conditions will differ between the two markets.
  • Wednesday, October 14, 3:30 p.m.: U.S. September Consumer Price Index (CPI). Core-price trends matter alongside energy's contribution.
  • Thursday, October 15, 3:30 p.m.: U.S. September Producer Price Index (PPI), a second check on companies' cost pressures. All times are Türkiye time.

My analysis

My first question entering the new week is whether regional tensions feed through to companies' costs. Oil's opening reaction will provide an initial signal, but it will not be enough on its own. Transportation disruptions, persistent price increases and high inflation together would warrant a more cautious view of earnings expectations. In that situation, an index rising on the strength of a few large companies would not reassure me.

In a more favorable scenario, transportation continues, the initial energy reaction subsides and inflation components ease. Earnings results would then carry more weight. I will distinguish investment in AI that translates into customers, revenue and cash from spending budgets that simply grow. Chip stocks joining the broader market's recovery would provide price support for that view.

For now, I am keeping some distance between retaining a long-term technology outlook and taking more risk in the short term. A strong Monday opening would not resolve all of the week's uncertainties. Sustained price moves, companies meeting expectations and easing cost pressures would be more persuasive together.
