In this episode, we sit down with Don Kieffer, senior lecturer at MIT Sloan School of Management and co-author of There’s Gotta Be a Better Way, to talk about what actually makes companies run well. Don has spent decades helping organizations, from Harley-Davidson factory floors to biotech labs, design better systems that unlock real performance. We break down the five-principle framework he developed with his co-author, Nelson Repenning, an MIT PhD, MIT Sloan professor, and leading expert in operations and systems thinking, for building operational excellence: solving the right problem, structuring for discovery, connecting the human chain, regulating for flow, and visualizing the work.

Through stories that range from front-desk hotel check-ins to a corrugated cardboard plant and even private equity fundraising pipelines, Don shows how tiny operational tweaks can deliver huge impact. We explore why firefighting cultures keep companies stuck in a “capability trap,” why automation without fixing the human system first is a mistake, and why the best private equity playbooks focus on execution, not spreadsheets. For founders, operators, and investors alike, this is a practical, no-fluff conversation about how businesses actually scale.

Before diving into operations, we also touch on recent rumblings in credit markets, continuing our discussion on the failed refinancing of First Brands and the liquidation of TriColor to bank fraud write-offs and how credit default swaps can amplify market stress. It’s a lively, two-part arc: first, the operational playbook; next, how top investors at Private Equity firms think about value creation inside portfolio companies.

This week on The Wall Street Skinny, we kick off discussing gold ripping to record highs and unpack why that’s happening in a still-high-rate world: sticky inflation keeping real yields muted, central-bank buying, safe-haven demand, and a dash of retail frenzy. We also poke holes in the “25/25/25/25” portfolio meme (equities/bonds/cash/gold) and talk through why allocation can’t be one-size-fits-all—age, goals, and cash-flow needs matter.

Then we dive into First Brands’ Chapter 11 and the alleged “Enron-style” shenanigans behind $2.3B of vanishing assets. We explain collateral, receivables/inventory financing, why overlapping pledges are a five-alarm fire, and who’s exposed (private credit funds at Street names like Jefferies and UBS get a mention). Bigger picture: what this says about today’s credit boom, looser covenants, and why fraud tends to surface when the cycle turns—plus what two auto-related bankruptcies might signal about the consumer/auto complex.

We also decode that viral “Ferrari-loving trader” headline: how a naked short in long bonds around the COVID shock morphed into an 11,000-to-1 leverage debacle and ~$250mm in Street losses—complete with a plain-English walk-through of bond shorting, repo, and settlement. Finally, we react to the Centerview analyst lawsuit over sleep accommodations and the perennial debate over banking culture, expectations, and realistic boundaries. Stick around for what’s next: a Distressed Debt 101 primer in November and a packed slate of heavyweight guests.

What does it really mean to be a "quant investor"? How do quantitative strategies fit into a modern portfolio? And what does it take to break into a quant investing career path?

In this episode, we sat down with Stacie Mintz, Head of Quantitative Equity at PGIM (one of the world's largest asset managers, with $1.4tr in AUM). Stacie's team oversees $60bn in quantitative equity strategies, and she joins us to break down what quant investing is, how it differs from other investment philosophies, what the role of human oversight is relative to AI, and what skills are essential for breaking into the field.

From factor investing and natural language processing to how quants think about risk and portfolio construction, this is a no-nonsense inside look at the world of systemic investing. We also do some myth busting work (spoiler alert: quant investing isn't just AI and algorithms gone wild), the evolving role of artificial intelligence, and why communication skills often matter just as much as your coding ability.

Whether you're just starting out in your career or you're an investor trying to understand how systematic strategies complement traditional fundamental analysis, this conversation is a crash course in Quant Investing 101.
