DEEP DIVE: AI's Low-Tech Problem

Nov 12, 2025 5 min read

With lofty valuations in AI-related stocks, it's understandable that investors are on edge about anything that might go wrong. Recently, concerns have centered on the ability to bring new AI data centers online at the volume AI providers require. While funding for construction is flowing, a lack of electricity and permitting — two very low-tech problems — might be the Achilles' heel of this otherwise high-tech industry. Demand for

Bad Day For the Big Short, Thanks To Dip Buyers

Nov 10, 2025 2 min read paid

Today was not a good day to be short AI stocks like Nvidia (up 5.8%) and Palantir (8.8%). They both rebounded dramatically, along with other AI stocks following last week's selloff (chart). Investors and traders bought the dip again. It's hard to short stocks in a bull market. The Magnificent-7 rose 2.8% today after falling 3.4% last week. The AI trade remains

MARKET CALL: From AI Zen To AI Jitters

Nov 9, 2025 3 min read

The S&P 500 peaked at a record high of 6890.59 on October 28 (chart). It is down 2.4% since then. It retested its 50-day moving average on Friday, falling slightly below it around noon. It then closed higher on the day on hopes that a compromise proposal from the Democrats might end the government shutdown. Negotiations are reportedly happening, but they remain tense and far from

MARKET CALL: Super-Duper Earnings

Nov 1, 2025 3 min read

S&P 500 earnings per share continue to beat expectations. Q3 earnings per share are on track to rise to a new record high. They are driving the S&P 500 stock price index to new record highs. The Magnificent-7 are leading the way higher on both fronts. As a result, the S&P 500 market-weight index continues to outperform the equal-weight index (chart). On Friday, Amazon

Just Another AI (Mania?) Day

Oct 27, 2025 3 min read paid

Today was just another day in the stock market. The S&P 500 rose to another record high of 6875.16. Also closing at record highs were the Nasdaq, the DJIA, and the Russell 2000. Been there, done it! More record highs are likely when the Fed cuts the federal funds rate by 25bps on Wednesday. On Thursday, President Donald Trump and Chinese President Xi Jinping are expected to

Data Centers: Too Much of a Good Thing?

Oct 8, 2025 5 min read

The lure of riches and tight capacity today has money flooding into the construction of artificial intelligence (AI) data centers. Data center construction—just the cost of building the building—has increased to an annual rate of $43.0 billion, up 30% y/y and 322% higher than $10.2 billion four years ago (chart). Add in the costs of chips and servers, and you’re talking about real money.

MARKET CALL: Nothing To Fear But Overvaluation & A Shutdown

Sep 28, 2025 3 min read

The financial markets have become jittery lately due to concerns about high valuation multiples, particularly among AI stocks, and a potential government shutdown. President Donald Trump reportedly will meet with the top four congressional leaders at the White House on Monday as the threat of a government shutdown on October 1 looms. Meanwhile, investors are once again wondering whether the massive spending on AI infrastructure by the "hyperscalers"

Nvidia Isn't Cisco

May 28, 2025 3 min read paid

As Nvidia's stock price soared during 2024, the naysayers compared its ascent to Cisco's roundtrip performance during the Tech Bubble of the late 1990s, which was followed by the Tech Wreck of 2000 and 2001 (chart). Cisco was the tech darling of the dawning Internet Age. Nvidia is leading the way in the AI Age. Cisco crashed when the Dot.Com Bubble burst. When DeepSeek was

The AI Trade

Mar 28, 2025 3 min read

Two months ago at the World Economic Forum in Davos, Microsoft CEO Satya Nadella said, "All I know is, I'm good for my $80 billion" regarding the $500 billion Stargate AI announcement. His comments followed the emergence of DeepSeek's R1 large language model and chatbot, which was supposedly trained at much lower cost than state-of-the-art models built in the US. A February note from

Back On The Happy Trail

Jan 28, 2025 3 min read paid

Today, the US stock market quickly confirmed our view that DeepSeek is a positive for the proliferation of AI, which should boost productivity and economic growth, especially in the US. The Nasdaq added 2% as Nvidia rose 9%. Both regained much of Monday's losses from the DeepSeek mini panic. It was yet another buying opportunity in the current bull market, as we anticipated in Sunday's QT.

Stocks Stay Afloat in Deep Waters

Jan 27, 2025 3 min read paid

DeepSeek took a bite out of semiconductor, other tech, as well as nuclear power stocks today. Many of these AI plays dropped by double-digit percentage points, and Nvidia fell 17%. Other than the impact of the largest US stock nearly entering a bear market in one day, plus some collateral damage in other large stocks, the broader market held up just fine. The S&P 500 fell less than

MARKET CALL: AI Coming To Vegas, Baby, Vegas!

Jan 5, 2025 3 min read paid

The Q4-2024 earnings reporting season is about to start, led by the big banks. We expect that during their conference calls, company managements will discuss how AI may be starting to boost their productivity. In effect, they'll be trying to convince investors that every company is now a technology company either producing AI hardware and software or using them. The AI excitement will be palpable this week. As
