BWB - Business With Brian
October 18, 2026
TL;DR
Chip stocks have fallen 9% despite S&P 500 profits growing 10% since June, creating buying opportunities in AI infrastructure companies with expected 15%+ profit growth that analysts have upgraded since July.
“Interest rates are to asset prices, you know, sort of like gravity is to the apple. When there are very low interest rates, there's a very small gravitational pull.”
— Brian Cohen
“Even the bubble crowd sees this. Steve Eisman, the investor famous from the Big Short, has been warning that this AI boom could end badly. But listen to what he owns. Nvidia, God bless them, and I own the stock.”
— Brian Cohen
“What happens when those profits stop growing? The slowdown is already baked into the forecast with profit growth expected to fall to around 3% by the middle of next year.”
— Brian Cohen
“Gravity only really wins when profits actually start falling. And right now analysts are raising their numbers on all five of these companies.”
— Brian Cohen
1. Market Context: Rising Rates Meet Growing Profits
US 10-year yield hits highest since 2002; S&P 500 slipped 1% but chip stocks fell 9% with all five featured stocks down over 9%. Since June, expected S&P 500 profits up 10% while prices only up 3.5%, creating a compression between rates (gravity) and earnings growth.
2. Stock Selection Filter and Investment Approach
Used three-part filter: companies must have 15%+ expected profit growth next year, analysts must have raised forecasts since July, and stock price must lag those higher forecasts. Brian Cohen uses a signal ladder system and emphasizes buying in stages while keeping riskiest positions extremely small.
3. Verdive: AI Data Center Cooling and Power Infrastructure
Makes radiators, fuel lines, and cooling gear for AI chips; profit per share up 60% last quarter with 36% expected growth, but stock down 31% since July. $1.4 billion acquisition of power company positions Verdive for upgrade cycle when Nvidia changes rack power design starting 2027. PEG ratio around 1.0 (fair price for growth).
4. Invent: Data Center Power and Liquid Cooling Systems
Sales jumped 53% last quarter; data center business grew from 12% to 60% of revenue; now expects to sell over $2 billion of data center gear this year, more than double last year. Stock down 9% despite 27% expected profit growth; bought competitor for $1.75 billion at 6% interest, creating debt burden in higher rate environment.
5. KLA: AI Chip Quality Control and Inspection Tools
Sales record up 35% last quarter with backlog topping $1 billion for first time; one packaging customer ordered $200 million with most not shipping until 2027. 80% expected growth in stacking and packaging inspection business; 44% overall profit growth puts PEG at 0.6 (discount to growth), but stock down 26% since July due to Chinese memory maker competition.
6. Comfort Systems USA: Data Center Construction and Modular Building
Sales grew 50% last quarter with profit per share nearly doubling; backlog up 73% to $14 billion with tech customers increasing from 43% to 60% of revenue. 23% expected profit growth with PEG of 1.3; stock down 16% in one month but beat Wall Street estimates four quarters in a row; risk is fixed-price contracts exposed to labor/material cost increases.
7. InoData: AI Model Training Data and Testing Services
Sales jumped 58% last quarter; writes practice problems and grades AI model answers for major tech companies; 27% expected profit growth but stock down 15% since July and trading at half June peak. Building motion capture lab for robots and testing AI for government; biggest risk is concentration with two customers comprising 71% of sales. New CEO as of September with $300 million stock offering plan limiting rallies.
8. Why These Stocks Are on Sale and What Comes Next
Higher interest rates create gravitational pull on stock prices, but profits are fighting back with S&P 500 seeing 10% profit growth. All five companies have raised analyst forecasts since July; earnings reports coming in next few weeks will reveal if growth engines still running. Historical data shows market handles profit slowdown to 3% but real damage comes when profits fall.
