Our September review identified 7,771 as the level that would decide whether the S&P 500 resumed its advance or confirmed an intermediate top. Four weeks later, the question remains open. The index tested that level repeatedly and was turned back each time, closing the period at 7,722, little changed from where it began.

Beneath that unchanged headline, the market divided. Technology leadership broke decisively higher, with the Nasdaq-100 reaching record levels. Most of the remaining market did not follow.

The Federal Reserve Raised Rates

On September 16 the Federal Reserve raised its policy rate by 25 basis points to a range of 3.75% to 4.00%, its first increase since July 2023. The decision was unanimous. Projections indicated one further increase, which matched what markets had already priced, so the decision itself produced no shock.

The economic data that followed pulled in opposite directions. Business activity accelerated, with the composite purchasing managers’ index reaching 58.4, its highest reading since July 2021, and input prices rising. Consumers moved the other way: consumer confidence fell to a twelve-year low, and the University of Michigan sentiment index registered the lowest reading in its history, with one-year inflation expectations at 4.6%.

The period closed with two softer reports. Core PCE inflation, the Federal Reserve’s preferred measure, came in at 3.0% year over year against expectations of 3.3%. September payrolls rose by only 29,000 against expectations near 85,000, unemployment rose to 4.2%, and wage growth slowed to its lowest pace since May 2021. Expectations for an October increase receded as a result.

Long-Term Rates Reached New Extremes

Our last review named a 30-year Treasury yield decisively above 5.35% as one of three signals of deterioration. That signal was met.

The 10-year yield rose to 5.33%, its highest level since April 2002, and the 30-year reached approximately 5.48%. Strong activity data, heavy Treasury issuance, and oil prices driven by the conflict involving Iran all contributed. Brent crude approached $107 in late September after a peace proposal was rejected, before easing back toward $100.

The mechanism we described in September continued to operate. Rising long rates again pressured interest-sensitive and long-duration sectors. The largest technology companies were the exception, advancing through the rise in yields on the strength of their earnings.

Financials Absorbed the Pressure

Bank stocks were the clearest casualty of the period. The KBW Bank Index fell 2.9% the day of the rate decision, its largest decline since February, and the group continued lower for most of the month.

The causes were largely specific to the industry rather than the economy. Second-quarter equity trading revenue at the largest banks had risen 72% year over year, a level management has said will not repeat. Corporate borrowers delayed bond and stock issuance pending clarity on rates, reducing underwriting fees. Goldman Sachs and Morgan Stanley, the most dependent on trading and underwriting, were among the most affected.

In our assessment, the fundamental condition of the leading institutions has not changed materially. Valuations have compressed, and the third-quarter earnings reports due in mid-October will indicate how much of the slowdown has already been reflected in prices.

Technology Broke Out While the Broad Market Waited

The defining feature of the period was the divergence between technology and everything else.

The Nasdaq-100 broke out of a four-month consolidation and reached record highs in the final week. Nvidia and AMD set new highs. Microsoft recovered to the top of a one-month base. Within the semiconductor group, equipment and networking names began forming constructive patterns for the first time since summer.

The broader index did not confirm that move. The S&P 500 remains inside a consolidation bounded by resistance at 7,771 to 7,782 and a rising lower boundary near 7,500. Roughly three-quarters of S&P 500 members closed the period below their 50-day moving averages, and on September 29 new 52-week lows outnumbered new highs by more than five to one across the broader market.

A market led by a small group of very large companies can advance for an extended period. It is, however, more fragile than one in which participation is broad, and confirmation from the broader index remains the most important outstanding signal.

The AI Trade Rotated Again

Our September review drew a distinction between companies converting AI spending into current earnings and those whose value depends on that spending continuing. The distinction held, with two developments worth noting.

First, the optical networking group, which we described in September as showing no constructive base formations, reversed. Lumentum cleared its resistance on volume more than 60% above average and traded above its prior all-time high, and related names began to stabilize. Leadership within the AI trade is rotating rather than narrowing.

Second, memory demonstrated the limits of good news. Micron reported record quarterly revenue of $54.2 billion and guided the following quarter 8% above consensus, with most of its 2027 high-bandwidth memory supply already contracted at higher prices. The stock did not advance. When results of that strength fail to lift a share price, the market is signaling that expectations had already absorbed them. Storage names fell sharply on the final day of the period.

A new category of risk also emerged. Meta’s AI agent, Muse, began to be priced as a potential disruptor of other industries, with travel-booking shares falling on the prospect that an agent could absorb their function. This is an early theme, but one we expect to recur across consumer-service businesses.

Bitcoin Reversed Its Downtrend

Bitcoin broke above its long-term downtrend in late September, completing an inverse head-and-shoulders pattern on rising volume and reclaiming its 50-week moving average. It closed the period near $86,000, above the level that would confirm the reversal on a weekly basis.

Gold moved in the opposite direction, falling roughly 4% in a single session on September 28, and several precious-metals miners broke down to new lows.

Quarter-End and Its Aftermath

Our September review asked whether the late-quarter rebuilding of positions in lagging names would prove durable once the quarter closed. The early evidence is mixed.

Microsoft and Dell have held their gains. Salesforce failed to complete its breakout and retreated. Robinhood remained highly volatile, at one point opening sharply higher on a product announcement and reversing the entire gain the same morning. The first sessions of October favored technology over financials, healthcare, and consumer staples, suggesting the year’s leadership has reasserted itself rather than rotated.

Technical Position

The technical picture is more constructive than in September, but not resolved.

In August and early September, the S&P 500 made a series of lower lows. Since then it has made higher lows within a narrowing range, held its 20-day and 50-day moving averages on a closing basis through successive tests, and rejected resistance near 7,771 four times. That pattern describes a market consolidating rather than deteriorating.

Outlook

The market has entered the fourth quarter with its leadership clearer but its breadth no better.

Three conditions would confirm a renewed advance: an S&P 500 close above 7,782 that confirms the technology breakout; stabilization of the 10-year Treasury yield below 5.25%; and a broadening of participation beyond the largest technology companies.

Conversely, three developments would indicate deterioration: a failure of the Nasdaq-100 to hold its breakout; an S&P 500 close below its 50-day moving average near 7,644 followed by a break of the consolidation’s lower boundary; and continued weakness in financials through third-quarter earnings.

Two events in the coming weeks will carry particular weight: bank earnings in mid-October and the Federal Reserve’s meeting on October 28.

Bottom Line

September produced the first Federal Reserve rate increase in three years, the highest long-term yields in more than two decades, and a technology breakout to new highs. The broad market absorbed all three and finished the period essentially unchanged.

The question we posed in September has narrowed rather than resolved. Leadership has emerged; breadth has not followed.

Until the broader market confirms what technology has already signaled, the appropriate posture remains selective participation in confirmed opportunities, with defined risk on every position.
