Episode Details

What if the best investing edge isn’t a chart pattern… but a business model?

Jim Iuorio and Bob Iaccino sit down with John Tinsman (Founder, AOT Invest) to break down why “low marginal cost” companies have dominated for decades—and how his ETF AOTG is built to target them.

In this episode, John explains the core thesis behind AOTG: prioritize high-growth, profitable businesses where the cost of serving the next customer is near-zero—then rebalance to keep growth high while lowering valuation metrics. We also dig into drawdowns, bear-market questions, why Apple isn’t always “growth,” and how passive market-cap indexing can distort allocations at exactly the wrong times.

What you’ll learn:

- Why “low marginal cost” is the hidden driver behind mega-winners (Visa, Microsoft-style economics)

- Why John focuses on profitable growth (and avoids speculative “story stocks”)

- How AOTG thinks about valuation (why Palantir got cut, why cheaper faster growers can win)

- What happens in a sharp tech selloff and how AOTG handles slowdowns / profitability changes

- Why John believes today’s Nasdaq is not the Nasdaq of 2000

- Rebalance cadence, portfolio turnover, and what can hurt this strategy
