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.
