Weekly Compounder Update | Tariff Tension, AI Partnerships, and Market Pullbacks

Welcome back to the Weekly Compounder Update. Each week I scan through the noise so you don’t have to, pulling out the developments that matter most for quality compounders. This week we will look at how macro pressures, trade risk, and AI infrastructure moves are shaping the field. Then we’ll dig into Microsoft, AMD/Nvidia, S&P Global, Netflix, and Lowe’s. Let’s get to it.

General News

• Tariff escalation rattle shakes markets (Reuters). Trump threatened a “massive increase” in Chinese import tariffs, sparking a selloff and rattling sentiment. The development adds pressure to already elevated valuations, particularly in technology and industrials.
• Government shutdown drags on, data flow impaired (Politico). The U.S. federal government is now on day 10 of its shutdown, complicating economic reporting. So far, the market’s response has been muted.
• Bank earnings are set to provide directional clarity (Reuters). Earnings season kicked off this week. Next week, several large banks, including JPMorgan, Goldman, and Citigroup, will report Q3 results. These reports should offer a clearer view of consumer health, credit demand, and the broader U.S. economy.

Company Spotlights 

Microsoft (MSFT)

What happened: Microsoft signed a multi-year partnership with Nebius worth nearly $19 billion to expand its AI infrastructure capacity. The deal ensures access to thousands of high-end GPUs at a time when supply remains constrained. 📖 Yahoo Finance – Microsoft Makes Deal with Nebius Worth Nearly $19 Billion

Why it matters: Capacity is now a competitive advantage in AI. By securing long-term compute supply, Microsoft is strengthening its ability to support Azure, Copilot, and its broader enterprise AI offerings. The move also shows how deeply hyperscalers are investing in physical infrastructure to meet demand for their services. For now, it appears the AI buildout remains one of the few areas where capital spending continues to accelerate across the tech sector.

My take: This level of spending highlights both the strength and trade-offs in Microsoft’s model. Free cash flow remains enormous at over $70 billion for FY 2025, down slightly from $74 billion a year earlier as more earnings are reinvested to maintain leadership in AI and cloud. The goal is to convert this investment cycle into durable, long-term returns. Few companies can commit this level of capital without leverage or margin pressure. For long-term investors, it reinforces why Microsoft remains one of the most dependable compounders in the market, using scale and balance sheet strength to fund its own growth.

AMD (AMD) and Nvidia (NVDA)

What happened: AMD announced a five-year agreement with OpenAI to provide roughly 6 gigawatts of compute power using its new AI chips. The deal gives OpenAI an alternative to Nvidia’s hardware and marks AMD’s largest push yet into the AI infrastructure market. 📖 PR – AMD and OpenAI Announce Strategic Partnership to Deploy 6 Gigawatts of AMD GPUs

Why it matters: This deal signals a credible second source for compute for companies like OpenAI. Competition can affect supply and pricing over time, but it does not immediately change Nvidia’s position. Nvidia still benefits from a full-stack advantage and sustained demand. 

My take: Competition is healthy. Nvidia’s margins have expanded rapidly in recent years as AI demand surged and the ecosystem consolidated around its platform. A maturing market with more credible supply is likely to pressure those margins over time, even if not immediately. Demand remains strong, but growth rates and incremental margin expansion are unlikely to persist as the industry evolves. Investors should watch Nvidia’s pricing power and cash conversion closely as competition increases, particularly given its premium valuation.

S&P Global (SPGI)

What happened: S&P Global announced plans to launch the S&P Digital Markets 50 Index, a new benchmark that combines cryptocurrencies and publicly traded crypto-linked equities. The company partnered with Dinari, which will issue a token that tracks the index. This gives investors exposure to both digital assets and traditional companies operating within the crypto ecosystem. 📖 Press Release – S&P Global to Launch Innovative Crypto Ecosystem Index

Why it matters: S&P Global is extending its core strength into a new area. Digital assets are becoming part of the investment landscape, but they still lack reliable benchmarks. By stepping in, S&P is bringing structure and credibility to a market that has operated without either. 

My take: S&P’s index business remains its strongest growth driver. Index-linked assets keep expanding around the world, and new products like this only extend that reach. This move positions S&P to capture the steady growth of passive investing and new asset classes. Since the business grows with assets under management, as opposed to market cycles, it offers one of the best examples of recurring revenues and high margin growth in finance.

Netflix (NFLX)

What happened: Netflix announced that subscribers can now play video games directly through its TV app for the first time. The update, revealed by co-CEO Greg Peters at the Bloomberg Screentime conference, extends Netflix’s gaming efforts beyond mobile. Users can now play select titles, including a Boggle-style word game and Tetris, without leaving the streaming interface. 📖 Bloomberg – Netflix Brings Video Games to Its TV Service for First Time

Why it matters: Gaming has been a slow build for Netflix, but this is its most visible step toward expanding engagement beyond video. With more than 270 million subscribers, even modest adoption could add value through higher engagement and lower churn. Netflix is also likely aware that gaming captures more screen time than any other form of entertainment among younger audiences. So this gives Netflix another way to compete for attention.

My take: It is unclear whether viewers will come to Netflix to play games or if this feature will remain a niche add-on. The gaming market is large, but Netflix’s advantage still lies in storytelling, not interactivity. As long as investments remain disciplined and the core streaming business stays healthy, this push is worth exploring. Still, live events, especially sports, appear to be the more interesting pursuit, offering greater potential to attract new viewers and strengthen engagement over time.

Lowe’s (LOW)

What happened: Lowe’s completed its acquisition of Foundation Building Materials (FBM), a major distributor of interior construction products with over 370 locations across the U.S. and Canada. The deal expands Lowe’s reach with professional contractors, enhances fulfillment capabilities, and adds new trade credit and digital tools for Pro customers. It follows the June acquisition of Artisan Design Group (ADG), which strengthened Lowe’s offering in flooring, cabinetry, and other finish materials. 📖 Press Release – Lowe’s Completes Acquisition of Foundation Building Materials (PR Newswire)

Why it matters: Lowe’s is executing on its Total Home strategy, which focuses on the $250 billion Pro market. The Pro segment has become its main growth engine, with mid-single-digit comparable sales in Q2 2025 after high-single-digit gains in late 2024. Pro sales now represent an estimated 25–30% of company revenue, or roughly $21–26 billion annually. The acquisitions of ADG and FBM accelerate these efforts by broadening product coverage and strengthening relationships with larger Pros in both residential and commercial construction.

My take: This acquisition demonstrates how determined Lowe’s is to close the gap with Home Depot in the Pro market. Home Depot’s Pro business is roughly 3-4x larger. The difference comes down to scale, logistics, and long-standing contractor relationships. By acquiring FBM, Lowe’s is betting it can take share, especially as housing activity normalizes and builders look for reliable distribution partners. The risk will be integration the business and retaining customers, but the strategy is sound. Expanding the Pro mix should make Lowe’s revenue base steadier, margins higher, and its valuation more durable over time.

Watchlist Movers (±3%)

As of mid-day Friday, October 10th, the market sell-off was broad, affecting much of the watchlist. Only two sectors—Consumer Staples and Utilities—were in the green as investors digested tariff headlines and early earnings sentiment. Consumer discretionary and information technology were both down more than 2 percent, reflecting the impact of the headlines.

Closing Thoughts

Markets continue to walk a fine line between optimism and risk. Tariff threats and political gridlock remind us that volatility is part of the game, and a little bit should be welcomed. It creates opportunity.

Recently, my articles have focused on preparation and top-of-the-cycle thinking. As the bull market roars on irrespective of valuations, it becomes prudent to think about how to manage risk—through due diligence, watchlists, and portfolio management. That way, when the pullbacks do come, we can act with discipline and conviction. These are the same qualities that help investors avoid emotional mistakes and stay in the game long enough for compounding to work.
