This week the WineDown moved to the morning. With Jason out and Mark heading to France, Lex and Mark recorded during Trader’s Workshop hours and ran the WineDown format instead: an opening bell segment on markets, a Schoolhouse Rocks lesson, and Beyond the Bell. The opening bell starts with a puzzle. The S&P 500 is near all-time highs and the VIX sits around 15, yet put skew stays sticky because demand for hedges rises as the market climbs. Heading into earnings season, Lex lists four things to watch: guidance for 2027, margins, whether AI capital spending is producing real revenue, and market breadth. Mark adds a striking statistic: since June, the Magnificent 7 are up about 19% while the rest of the S&P 500 is roughly flat, and most of that gain comes from just four names. Mark thinks earnings moves are now priced very efficiently; Lex still trades them, using non-directional structures such as double calendars, double diagonals and condors built around the expected move. He notes the at-the-money straddle prices only about 80% of the statistical expected move. The main lesson is payment for order flow. Mark, who writes about market structure, argues that despite a name that sounds like payola, PFOF is one of the best structures retail traders have. When you send an order, your broker routes it to a wholesaler, which pays the broker for the flow and must fill it at least as well as the public quote, and usually better. Three forces keep that honest: competition with other market makers, a best-execution obligation, and monthly execution-quality reviews in which wholesalers that don’t improve prices lose their share of the broker’s flow. Why do market makers pay for small orders? Not because retail traders are uninformed, but because one- to five-lot orders don’t move prices, so the risk is easy to hedge. A 10,000-lot order can shift implied volatility and leaves a dealer with concentrated risk. Flow that consistently predicts direction is called “toxic,” and dealers won’t pay for it. They also cover the line between customers and professional customers: more than 390 orders a day, roughly one a minute, averaged over a quarter. Mark’s advice for retail traders using automation: if you’re placing that many orders, you’d better be a real professional. Beyond the Bell is short: Mark is off to France for a week with his family, back in his old neighbourhood, and promises to scout wine for a future episode. Key takeaways: – Low VIX at record highs can hide sticky put skew. – This earnings season hinges on guidance, margins and AI capex returns. – PFOF generally improves retail fills through competition, regulation and broker reviews. – Small orders are valuable to market makers because they’re easy to hedge. This episode is educational and not a recommendation. |
