Accenture +18%, Synopsys +8%: AI Comeback, Midday Read

AI comeback — Accenture +18%, Synopsys +8%, optics +9% while all three US indices slip

Three in four S&P 500 stocks fell in September, and today looks the same: the Dow, the S&P 500 and the Nasdaq are all lower, while anything that can show it gets paid for AI jumps. The surprise is who: Accenture, sold as an AI loser in the first half, rises 17.9% on record bookings. Memory and storage stay flat despite superb results.

In this edition

The Midday 10 Thu, Oct 1, 2026 ~60 seconds 12:15 ET

September was a broken market. Three in four S&P 500 stocks fell during the month, CNBC reported, and Morgan Stanley counts only 49% of index members above their 200-day average, down from about 75% earlier this year. The index itself held up because a handful of very large companies, most of them tied to AI, kept rising.

Our own chip section shows the other side of that split. Of the 85 chip stocks we track, 68 rose in September and 66 trade above their 200-day average. Either you are somewhere in AI right now, or you are losing.

Today repeats the pattern with a twist. All three US indices are lower: the Dow down 0.50%, the S&P 500 0.32%, the Nasdaq 0.39%. Banks, home improvement, travel and online retail all fall. The winners include companies the market had filed under AI losers in the first half: Accenture jumps 17.9%, the IT-services group follows, and software is higher. Memory and storage, the big winners of the first half, stay flat.

The ten lines

  1. 1

    LEVEL Breadth: 75% of S&P 500 stocks fell in September; only 49% trade above their 200-day average (Morgan Stanley), from about 75%; in our chip section 68 of 85 rose and 66 sit above the 200-day

    Morgan Stanley's Mike Wilson reads it as a market narrowing into quality and advises staying with large, profitable companies while adding riskier stocks in October. Strategists also note that the median S&P 500 company is still growing earnings by more than 15%. Our data says where the narrow market lives: in chips, 80% of names rose last month.

  2. 2

    DOWN All three indices lower: Dow 50,651.13 (−0.50%), S&P 500 7,626.87 (−0.32%), Nasdaq 26,755.92 (−0.39%); equal-weight fund RSP −0.13%, small caps IWM −0.28%; chip index SOX +0.47%, software fund IGV +0.25%; TLT $77.65 (+0.23%), 30-year yield 5.61%

    The morning's green futures did not hold. The broad market is red, while chips and software are slightly higher. Software opened strong and has given back most of it. Long bonds bounce a little but stay below the 78 level that broke on Wednesday.

  4. 3

    UP Accenture $216.21 (+17.91%) on record bookings; IT services follow: Cognizant +6.72%, EPAM +6.48%, Infosys +5.90%, Gartner +3.76%, Capgemini +7.38% at the Paris close

    ACNEPAMITCTSHINFYCAP.PA

    Revenue of $18.7 billion and EPS of $3.29 beat the estimates on our card ($18.03 billion, $3.18). New bookings were $22.2 billion in the quarter and a record $84.5 billion for the year, with 141 contracts worth $100 million or more. The fear all year was that AI agents shrink the hours Accenture bills; the bookings say companies are paying Accenture to put AI to work. On our Print Record card, the three-session window after a report never moved more than 6.0%, and seven of ten moved less than 3%. Today's jump comes before this window even opens: it starts from today's close and is graded on Tuesday's close.
