Nasdaq leads Wall Street gains as SpaceX, Super Micro boost AI sentiment

Nasdaq leads Wall Street gains as SpaceX, Super Micro boost AI sentiment

It was good news all around today with SpaceX soaring 7.8% on the news of showing its first profits since going public and Super Micro boasting similar glad tidings. The good feelings seeped into other tech companies and particularly AI with HPE and Dell also amongst the day’s winners. This was enough to alleviate the anxieties of AI being overvalued and both tech and industrials shot up a very respectable middle 3-digits with the chip index getting a very nice 2% boost.

It was yet another one of those days where concerns over AI’s potential profitability due to its excessive debt load sent the tech investors into cautionary mode with the Nasdaq not moving the needle much and closing flat while the S&P enjoyed a 60 point gain until 11 a.m., then plummeting and staying down the rest of the session to close modestly up.

Today’s expert put it best. “Nothing changed between Friday’s close and this morning’s open, other than nothing bad happened over the weekend, and sentiment had gotten so negative that we were oversold to the point that a bounce was due.” And that’s exactly what happened in tech and particularly AI as monies flowed steadily back into both the Nasdaq and S&P. And as is usually the case, the monies came out of industrials and the defensive sectors. There were handsome gains all around and the Dow, though closing nominally in the red, bounced back and forth between a minus 140 and a plus 130.

Today, a 3% jump in oil prices combined with serious concerns over debt-laden AI pushed all the indexes straight down in a big way, especially the Nasdaq that lost 572 points and dove 4% for the week, its sharpest fall since June and the S&P its sharpest since January. The AI companies have all cratered under all the debt pressure and the likelihood that all that debt will soon become even more expensive.

PPI came in today with the worst increase in 4-1/2 years providing even more fuel to Wednesday’s hot CPI readings on the inflation. This further aggravated all the concerns about inflation, particularly with the AI stocks which, with the prospect of higher interest rates, would be seriously impacted due to their extraordinary debt loads. So there was a rotation back to standard industrials which saw the Dow skyrocket 556 points while the tech indexes both tanked, the Nasdaq diving almost 400 points at open but gradually recovering these losses to even see a little green by close.

The surging costs of gasoline and more took today’s CPI to bigger heights than expected and that sent all of tech into a major downward spiral from the open and steadily down all day. The Nasdaq lost over 500, the S&P nearly 100. This has greatly bolstered bets for a very unwanted October rate hike, up to a whopping 37% in one day vs Wednesday’s 22% vs a mere 17% last Friday, odds doubling in one week.

The big banks missed estimates in today’s Q3 reporting and that sent all three indexes down, the Dow logically hit the heaviest down 3-digits. But earlier the tech indexes were hit much heavier, the Nasdaq down 130 by noon but then recovering to much more modest losses by close. Ditto for the S&P. What didn’t make sense is that both Citi and Goldman Sachs beat estimates but still fell. And despite expectations of a strong Q3, the S&P is trading at 19x, its lowest multiple in three years.

Because of weekend attacks on Saudi Arabia, the price of oil shot up over $2/barrel which shot the Dow way up and the tech indexes way down. Though an 11^th hour rally allowed the S&P to close flat, both the Dow and Nasdaq moved by 3-digits. But Tuesday begins Q3 reporting so Friday’s big optimistic rally got reversed to some cautionary sell off today not only awaiting big bank results but also new data on consumer and producer inflation as well as retail sales.

All the concerns about inflation, etc went on the back burner today when the markets decided to hang their hat on Q3 optimism with reporting starting with the big banks next week. Right out the gate there was a very substantial rally that shot both the Dow and tech up to very impressive 3-digits again. Trump’s announcement that there will be no more attacks on Iran before the midterms also momentarily relieved war anxieties. All three indexes logged weekly gains and Q3 S&P earnings growth is still expected to top 30%.

A combination of oil rigs being shut down as a hurricane precaution plus a smattering of new attacks on oil tankers in the Strait of Hormuz has shot oil prices up again and again raised the ugly specter of inflation after a brief pause in the last couple of days. Inflation scares always hit tech the hardest and that was certainly the case today.

Inflation concerns are back on the front burner as Treasury yields continue to climb after Tuesday’s brief respite. All the worries that have besieged the markets in recent weeks are back out front today as yields touched a 24-year high. The massive global selloff in the bond markets in recent weeks have particularly rattled investors. Oil prices are getting some relief since the International Energy Agency has sped up the release of stocks. The good news is that the day started much worse, with all three indexes down sharply right out the gate, the Dow at minus-600 at 11 a.m,, the Nasdaq down over 250.

Tue October 6, 2026  

With more oil flowing from the Middle East and also the Group of Seven nations, the price of crude has been easing and that has triggered an easing in Treasury yields as well, all good news on the inflation front. This created another very nice rally today with another rounds of impressive 3-digit gains in both industrials and tech. The concerns that have been haunting investors in recent weeks (and some might say even months) have begun to abate.

For a second day, the indexes were straight up out the gate still basking in the good news of optimism that there will be no rate hike in October, reinforced again by continuing falling oil prices with Middle East exports increasing. The soft inflation news as always proved a big boon to the tech sector with the Nasdaq gaining an impressive 3-digits again, closing with still another record high. October rate hike odds have again been lowered, today at a mere 24% vs 70% a week ago.

The markets have been looking for signs of inflation easing and they got that today with a government jobs report showing only 1/3 as many new jobs as forecast and additionally a reduction of 30K jobs from August. With the labor market stable but not as hot as expected, this has again lowered the odds of an October rate hike to just 21% vs Thursday’s 28.2% vs 70% earlier in the week. Thus, all the indexes shot way up right out the gate and stayed there all day.

After spending most of the day in the red, the indexes all rebounded in the afternoon to close just above break-even.  Treasury yields continued to climb with the 10-year hitting a 24-year high. PMI came in 2 points lower than August due to increased input prices which again raises the specter of inflation. In good news, jobless claims dipped 3,000 below the 200,000 forecast indicating a solid job market.
