Stax Lab Reports
Real news. Real strategies. Real data.
Every report starts with a headline and breaks it down using Stax. We pick the metrics, build the screen, backtest the strategy, and show you exactly what worked and what didn't.
AI Hyperscalers Face $725 Billion Capex Scrutiny. We Tested If Quality Outperforms Momentum.
Hyperscalers are projected to spend a historic $725 billion on AI infrastructure in 2026. However, the market is beginning to demand proof of return. We used Stax to backtest whether filtering for capital expenditure coverage and return on invested capital protects tech portfolios during capex scrutiny, or if buying pure momentum remains the superior strategy.
Uber Bid $11 Billion for Delivery Hero. We Tested Whether You Should Buy the Acquirer or the Target.
Uber offered roughly $11 billion for Delivery Hero, and Delivery Hero said no. DoorDash is circling the same assets. The food delivery industry is consolidating at speed, and that raises a question most investors get backwards: when an industry enters M&A mode, do you want to own the companies spending billions to buy their competitors, or the companies getting bought? We built two Stax strategies to find out, and the answer surprised us.
A $6.1M Insider Transaction Looks Bullish Until You Read the Filing. Here Is What It Actually Tells You.
Stax Labs flagged a $6.1 million insider transaction in Roivant Sciences (ROIV) three days ago. On the surface, it looks like a massive vote of confidence: 200,000 shares at $30.27 from the company president and Immunovant CEO, Eric Venker. But the filing tells a different story. We dug into the SEC data, explained what this transaction actually is, and then used Stax to test a bigger question: do the quality fundamentals that real insider conviction targets actually beat simple momentum?
A Congressman Bought AT&T. The Thesis Behind It Beat Momentum by 9 Points.
On May 17, 2026, Rep. Tim Moore (R-NC) purchased between $15,000 and $50,000 of AT&T stock. Moore sits on the House Financial Services Committee and its Subcommittees on Digital Assets, Financial Institutions, and Oversight. It is a quiet, mid-size buy in a mature telecom that most growth investors would ignore. We used Stax to reverse-engineer the financial profile behind the purchase, build it into a testable strategy, and backtest it against a momentum-driven alternative. The boring thesis outperformed.
A Congressman Bought Defense, Banks, REITs, and Tech in the Same Week. The Real Signal Was Simpler Than You Think.
On May 7, 2026, Rep. William R. Keating (D-MA), a member of the House Armed Services Committee, purchased positions in JPMorgan Chase, Northrop Grumman, Simon Property Group, and VMware LLC. The headline writes itself: "Armed Services Committee member buys defense stock." But the more interesting pattern is what all four picks share underneath the surface: strong return on equity, durable operating margins, moderate leverage, and consistent cash generation. We used Stax to test whether that financial fingerprint, not the congressional headline, actually works as a systematic investment strategy.
