Stock Market Caps Winning Week as Oil Eases and Bitcoin Rebounds

A Friday relief rally after a rough week

Wall Street ended a choppy week on a firm note. All three major U.S. indexes closed higher on Friday, October 9, and the gains carried each of them to a weekly advance. The Dow Jones Industrial Average led the session, rising 423.31 points, or 0.83%, to 51,654.95. The S&P 500 added 0.59% to 7,811.54, and the Nasdaq Composite gained 0.64% to 27,366.17.21 That leaves the S&P 500 close to its all-time high as investors get ready for earnings season, which starts next week.23

Most coverage gives the same reasons for the rebound: oil came off Thursday's spike and technology shares recovered from a selloff tied to AI stocks.2223 The Nasdaq's gain followed a bruising Thursday. On that day the tech-heavy index fell 1.3% and the S&P 500 lost 0.5%, as rising Treasury yields and new geopolitical worries hit semiconductors in particular.4

The Dow's lead stands out. One market wrap read it as a rotation into cyclical, old-economy stocks such as industrials and financials, and away from the growth names that have led for most of the year.27 That reading looks right. With rate-hike talk back and bond yields near multi-decade highs, a market that favors balance-sheet-heavy cyclicals over long-duration tech is pricing in tighter money.

The weekly scorecard depends on who's counting

The weekly figures vary a little by outlet. One live blog put the S&P 500 up about 1.2% for the week, the Dow up 0.9% and the Nasdaq up 0.6%.21 A weekly market review gave similar numbers: 1.15% for the S&P 500, 0.93% for the Dow and 0.64% for the Nasdaq. It also noted that the small-cap Russell 2000 fell for the week.7 Another outlet had the Dow up 1.15%, the S&P 500 up 0.95% and the Nasdaq up only 0.19%.26 Whichever set is used, the picture is the same. The broad market ended higher, but the gains were modest and uneven, and the Nasdaq had the hardest week after its midweek drop.

That drop is worth noting because the week started strongly. On Monday the Nasdaq and Nvidia both closed at record highs, with Nvidia's market value approaching $6 trillion.2429 By Tuesday the 10-year Treasury yield had reached 5.31%, its highest close in 24 years.29 A week that opened with records and then lost momentum suggests the AI rally is now very sensitive to the bond market.

Moderna leads the movers

Moderna was the standout stock. Shares rose 9.22% on the day the company officially rejoined the Nasdaq-100 index.26 Separately, vaccine makers rallied on a National Institutes of Health push for cancer vaccines, which matters most for Moderna because it is developing a personalized mRNA cancer vaccine with Merck.21 The stock is up more than 600% this year, making it the best performer in the S&P 500. One count puts the year-to-date gain at 627%.2123

Coverage divides into two explanations here: index inclusion or the policy news. Both probably played a part. Index inclusion forces funds that track the Nasdaq-100 to buy the stock, and the NIH news gives investors a reason to keep holding it. A gain of more than 600% in a year means Moderna is now trading on expectations as much as on results.

Not every sector shared in the rally. Telecom stocks fell sharply on fears that SpaceX, Elon Musk's company, will bring new competition to the industry.22 T-Mobile was among the day's notable movers.26

Oil: a risk premium that hasn't gone away

Friday's stock rally depended on the oil market, which is still driven by the U.S.-Israeli war against Iran, now in its eighth month.1 On Thursday, Brent crude closed up 4% at $104.28 a barrel and West Texas Intermediate rose 3.6% to $91.49. Two things drove the move. Iran stepped up attacks on tankers in the Strait of Hormuz, and Hurricane Isaias threatened production in the U.S. Gulf of Mexico.5 The data firm Kpler counted 10 tankers struck in the strait between September 28 and October 4, far above the previous weekly record of six. Only seven tankers crossed the strait on one day that week, the fewest since late July.6

Tensions eased after President Donald Trump said the U.S. would not attack Iran before the November midterm elections. Earlier, NBC News had reported that his national security team was considering new strikes.5 Trump also said the two countries were holding productive talks. Iran's foreign minister said Tehran was reviewing the U.S. response to an Iranian proposal that could reopen the strait within seven days.8

Reports differ on Friday's oil move, and the difference matters. Several stock-market wraps said lower oil prices helped lift stocks.2223 Early Friday, Brent was down more than 1%, near $102.8.2 But it recovered and settled up about 0.4%, near $104.72, while WTI settled around $91.85.3 Even after the reassurance from Washington, crude ended the day higher.

The physical market explains why. Producers shut in roughly 72% of Gulf of Mexico crude output as Isaias approached. The cost of shipping crude from the Persian Gulf to East Asia is now more than six times its prewar level. Dated Brent, a physical benchmark used in Europe, rose above $135 on Thursday.3 A TD Securities strategist said the need for U.S. Navy escorts and the constant risk of attack justify a lasting risk premium, even though crude flows from the region have largely recovered.5 ING analysts made a similar point: prices will only fall for good once the underlying risks are dealt with.6

Policy is pulling in both directions. The U.S. imposed new sanctions on 17 vessels carrying Iranian crude.2 The International Energy Agency said it would speed up the roughly 100 million barrels still left in its emergency release.6 In our reading, a promise to hold off strikes until the midterms delays the risk rather than removing it, and pricing in oil will reflect that.

Why oil and yields matter for stocks

Oil feeds into stocks through inflation and interest rates. Higher energy costs raise expectations that central banks will have to raise rates.1 Thursday's oil spike set off selling in global bond and stock markets, and the 10-year UK government bond yield reached its highest level since 2007.1 In the U.S., yields eased from their multi-decade highs later in the week after strong demand at Treasury auctions.7 The 10-year was around 5.24% on Friday.19

For now, U.S. stocks are absorbing this. A weak September jobs report earlier this month reinforced expectations that the Fed will stay on hold.25 Analysts are also unusually optimistic: 60% of S&P 500 stocks carry Buy ratings, a record.24 Still, a market near record highs with 5% bond yields and $100-plus oil leaves little room for error once earnings season starts.

Crypto bounces but stays in a range

Crypto-linked stocks outperformed on Friday. Bitcoin moved back toward $83,000 after falling toward $81,000 the previous day. Coinbase shares rose nearly 5%.11 Coverage tied the rebound directly to Trump's comments on Iran. Strategy, Michael Saylor's bitcoin-holding company, rose 2.5% in morning trading and Robinhood gained 1.5%.19 Analysts' price-target increases also helped. Barclays raised its Strategy target to $175, and Morgan Stanley raised its Coinbase target to $258 and its Robinhood target to $160.19 Not every target moved up: Citizens cut its Coinbase target from $325 to $280.11

The longer view is less encouraging. Bitcoin was still down 2.2% for the week, on pace for its worst weekly drop since September.19 It sits about 34% below its October 2025 record of roughly $126,080. Its next hurdle is the $85,000 to $87,000 range, where earlier recoveries have stalled.11 Earlier in the week it came within about $500 of its late-September peak near $87,400 and fell back, its second failed attempt in a week.14

Strategy now reports holdings of 848,000 bitcoin after buying another 334 coins.11 That makes its stock essentially a leveraged bet on bitcoin's price. Coinbase is a different story. One analysis found that despite a stronger balance sheet, Coinbase's share price has lagged its peers, with revenue down 18.5% from a year earlier.20

Crypto is reacting to the same forces as stocks. Higher yields and oil-driven inflation fears reduce the chances of Fed easing, which bitcoin has relied on during this recovery.11 Until bitcoin moves decisively above $87,000, Friday's gains look like a bounce within a range, not a breakout.

What to watch

The direction for the coming weeks depends on three things: whether tanker attacks in Hormuz ease, what Hurricane Isaias does to Gulf Coast production and refining, and whether earnings can support valuations while 10-year yields stay above 5%. Friday showed that markets will rally on any sign of calm. The physical oil market, which settled higher anyway, shows that the risk hasn't been resolved.
