Stock Market Update

[BRIEFING.COM] The major averages are trading at session highs at midday, with the S&P 500 (+0.7%), Nasdaq Composite (+0.9%), and DJIA (+0.2%) extending their gains as buying interest has broadened considerably from the narrow, mega-cap-driven advance seen shortly after the open. The Russell 2000 (+0.6%) and S&P Mid Cap 400 (+0.8%) have followed a similar trajectory, recovering from weaker early performances to trade firmly higher.

The improvement in participation is particularly notable given the recent divergence between the largest stocks and the rest of the market. The Vanguard Mega Cap Growth ETF (+0.8%) continues to provide meaningful support to the major averages, but the S&P 500 Equal Weighted Index (+0.6%) has caught up with the market-weighted S&P 500 after trading lower earlier this morning. The Equal-Weight S&P 500 entered today's session riding a seven-week losing streak, underscoring the extent to which recent index-level strength has been concentrated among the market's largest stocks.

The communication services sector (+0.9%) and information technology sector (+0.6%) remain firmly higher after providing much of the market's early leadership. Meta Platforms (META 744.74, +16.66, +2.29%) continues its recent run following the release of its Muse AI agent, helping the communication services sector remain near the top of the standings.

Software stocks are providing much of the support within the information technology sector, offsetting a modestly weaker showing from semiconductor stocks. PTC (PTC 193.00, +48.97, +34.00%) is surging after Schneider Electric (SBGSY 61.34, -7.06, -10.31%) agreed to acquire the company for $205 per share in cash, while Microsoft (MSFT 526.42, +8.89, +1.72%) is another notable winner following an upgrade to Buy from Hold at Melius. The iShares GS Software ETF is up 1.0% and has returned to its August highs.

Mega-cap strength extends beyond those groups, with SpaceX (SPCX 167.42, +8.46, +5.32%) firmly higher again today following Friday's sizable advance.

Still, the defining change as the morning progressed has been the expansion of buying interest beyond the largest growth stocks. The materials sector (+1.1%), energy sector (+1.0%), and utilities sector (+0.9%) have all emerged as standouts. The energy sector's strength comes despite another decline in crude oil, with oilfield services names Halliburton (HAL 33.08, +1.24, +3.88%)  among the group's leaders. Refiners Valero Energy (VLO 418.50, +12.20, +3.00%) and Marathon Petroleum (MPC 434.24, +11.92, +2.82%) are also extending their record runs following a Bloomberg report that the Trump administration plans to lower limits on tax-exempt diesel.

The improved participation has left the real estate sector (-0.1%) as the only S&P 500 sector in negative territory, a substantial improvement from the weaker breadth seen shortly after the opening bell.

Corporate news is relatively light today, although C.H. Robinson (CHRW 138.30, -19.42, -12.31%) is a notable laggard after agreeing to acquire RXO, Inc. (RXO 28.50, +5.12, +21.90%) in a stock-and-cash transaction valued at $5.8 billion.

Today's advance is also occurring despite another rise in Treasury yields, which have been one of the market's primary headwinds recently. The 10-year note yield is currently up six basis points to 5.34%, yet stocks have continued to grind higher rather than retreat in response to the renewed rate pressure.

The broader participation offers a welcome change from the market's recent pattern, particularly after seven consecutive weekly declines for the Equal-Weight S&P 500. Some of today's buying in previously lagging areas could reflect a response to increasingly extended conditions among recent leaders, but notably, that broadening has occurred without a corresponding retreat in mega-cap stocks. Instead, the market's largest names continue to move higher ahead of the upcoming earnings season, potentially reflecting continued confidence in their earnings prospects even as investors broaden their exposure elsewhere.

Reviewing today's data: 

• Sep S&P Global U.S. Services PMI - Final 58.8 (Prior 58.7)
• Sep ISM Non-Manufacturing Index 54.9 (Briefing.com consensus 55.7; Prior 55.4)
  • The key takeaway from the report is the understanding that the prices paid by services organizations continue to increase. In turn, that will continue to feed concerns about pass-through effects for consumers.
