Stocks closed the week with a Friday rally. The long end of the bond market didn't join in

Wall Street finished the last full trading week of September on firmer footing than it started the day. After a Thursday session that ended almost exactly flat, buyers stepped in on Friday and held their ground into the closing bell. The Dow Jones Industrial Average gained about 0.9%, a move of roughly 478 points that left the blue-chip index near 51,800, according to Kiplinger's closing tally and Bloomberg's markets wrap. The S&P 500 added about 0.5% to finish a little above 7,740, and the Nasdaq Composite rose roughly 0.5% to about 27,070.

The weekly scorecard looked better than the daily one. The S&P 500 rose a little more than 1% over the five sessions and the Nasdaq gained about 2%, helped by a Tuesday record close for the tech-heavy index. Kiplinger's figures showed the Dow ending the week modestly higher as well, which would snap a three-week losing streak for the blue-chip average.

Oil gave stocks the opening they needed

The day's biggest macro input came from the energy market. Crude prices fell about 2% after reports that U.S. and Iranian negotiators meeting in New York were exploring a phased path out of the war, one that could involve Tehran reopening the Strait of Hormuz and Washington lifting its economic blockade. Brent, the international benchmark, settled around $104 a barrel, according to Reuters, after trading above $106 a day earlier.

Lower oil matters for stocks through two channels. It eases the cost pressure on fuel-hungry industries such as airlines, shipping and retail, and it takes a little heat out of the inflation outlook that has been pushing bond yields higher. On Friday, the second channel was the one investors cared about most.

A split decision in the Treasury market

Bond traders did not treat the curve as one market. The two-year Treasury yield, which tracks expectations for Federal Reserve policy, fell several basis points to about 4.85%, according to both Kiplinger and Bloomberg. The 10-year yield edged lower to around 5.16%, still close to Thursday's peak, which was its highest level since 2007.

The 30-year bond went the other way. Its yield rose slightly to about 5.49%, near its highest level in roughly two decades. When short-term yields fall while long-term yields hold or climb, the curve steepens, and that pattern usually says investors are less worried about the next few Fed meetings than about the longer run: sticky inflation, heavy government borrowing and the extra compensation lenders demand for tying up money for decades.

Cleveland Fed President Beth Hammack offered a similar diagnosis on Friday, saying long-term yields are being driven higher by a stronger growth outlook, concerns about government debt and expectations of additional rate increases, according to Bloomberg.

Leadership stayed narrow

The index gains hid a divided tape. At midday, seven of the 11 S&P 500 sectors were lower and declining stocks outnumbered advancers on both the NYSE and Nasdaq, according to FXEmpire's session analysis. Technology did most of the lifting, led by Microsoft, Qualcomm and Dell, while several rate-sensitive groups lagged.

That pattern has defined the week. A relatively small group of AI-linked companies, from software to chips to data-center hardware, has carried the major averages while much of the rest of the market has struggled against the rise in borrowing costs. A gauge of chipmakers posted its longest weekly winning streak since May, Bloomberg reported.

Gold and the dollar

Gold spent Friday hovering near $4,300 an ounce and was on course for a weekly decline of roughly 1.5% to 2%, according to several market reports, as high real yields raised the cost of holding a metal that pays no interest. The yen strengthened after Treasury Secretary Scott Bessent said he had discussed the desirability of a strong currency with Japan's finance minister, Bloomberg reported.

What carries into next week

The Fed question has not gone away. Traders were pricing roughly a 64% to 70% chance of another quarter-point increase at the Oct. 27-28 meeting, depending on the hour and the source, based on the CME FedWatch tool. Swaps pricing points to about three more quarter-point moves over the next year, according to Bloomberg and Trading Economics.

The next big test arrives on Sept. 30, when the Commerce Department publishes the August personal consumption expenditures price index, the Fed's preferred inflation gauge. Economists expect headline and core readings to tick higher from July, according to a preview in The Epoch Times. A hotter-than-expected print would likely reinforce the October hike pricing; a softer one could give the front end of the curve more room to rally.

Oil remains the swing factor. The truce talks are a negotiation, not a reopened shipping lane, and any setback could reverse Friday's slide quickly. For now, the week ended with stocks higher, short-term yields lower and the long bond still signaling that the market's inflation worries are far from settled.
