The S&P 500 may be hitting record highs, but that doesn’t mean most stocks are sharing in the rally. A handful of mega-cap technology companies, including Nvidia, Microsoft, Apple and Meta, have had an outsized influence on the index, highlighting why its performance may not reflect what investors are experiencing in their own portfolios.

Beyond the Obvious: Finding Hidden Opportunities
Major investment trends don’t always benefit the companies making the headlines. Sometimes the more interesting opportunities can be found further down the supply chain, in businesses providing the equipment, infrastructure, and services needed to support that growth. Generac’s recent deal to supply backup generators to Amazon’s data centres is a good example of how AI can create opportunities well beyond the technology companies at its centre.
Monthly Portfolio Update July 2026
July was a month of shifting investor preferences, with the major indexes moving in noticeably different directions. The Toronto Stock Exchange Composite Index (TSX) and Dow Jones Industrial Average (DJIA), with their greater exposure to traditional companies, extended their monthly winning streaks. Meanwhile, the more growth-oriented S&P 500 Index (S&P) and Nasdaq Composite Index (Nasdaq) extended their monthly losing streaks. Just as the markets had a mixed month, so did my three portfolios. And like the major indexes, the portfolios showed how different sector exposure can produce very different results, particularly when technology stocks fall out of favour.

The AI Revolution: Understanding the Technology Behind the Investment Boom
Artificial intelligence (AI) may seem like software running in the cloud, but behind every AI-generated response is a vast physical infrastructure. From Nvidia’s powerful AI chips to advanced memory, high-speed networking, massive data centres, and enormous amounts of electricity, today’s AI systems depend on some of the most sophisticated technology ever built.
In Part 3 of The AI Revolution: Understanding the Technology Behind the Investment Boom, we explore the infrastructure that makes AI possible and explain why companies across multiple industries—not just technology firms—are benefiting from the AI revolution.

The AI Revolution: Understanding the Technology Behind the Investment Boom?
Artificial intelligence (AI) may seem almost magical, but behind every AI-generated response is a complex learning process. After exploring what AI is in Part 1 of The AI Revolution: Understanding the Technology Behind the Investment Boom, we now look at how AI actually learns.
In Part 2, we explain what training data is, how AI models are created, why building them requires enormous computing power, and the difference between training an AI model and using one. Understanding this process helps explain why companies are investing billions of dollars in the technology and infrastructure behind the AI revolution.

Why Interest Rates Impact Some Stocks More Than Others
After better-than-expected inflation reports helped push markets higher, technology stocks led the charge while more defensive sectors lagged. The difference comes down to a key investing concept: some stocks are far more sensitive to changes in interest rate expectations than others.
In this week’s update, I explain why growth stocks like Nvidia often react differently than dividend-paying companies like utilities, and how Fed policy influences investor behaviour.
