Options Boot Camp 370: More Trouble With Vertical Spreads

In this episode of Options Boot Camp, your drill instructors Mark Longo and Dan Passarelli dive back into the trenches to tackle a recurring nightmare for retail traders: why "perfect" vertical spreads sometimes result in losses. Following up on a "horror story" from a previous episode involving Marvell (MRV), the team breaks down the mechanics of spread books, broker liquidations, and the hidden risks of trading around major events.

In This Episode, You'll Learn:

• The Marvell Meltdown: A deep dive into a listener's trade where a winning call vertical on MRV resulted in a loss due to after-hours volatility and broker liquidation.

• The Reality of Vertical Spreads: Why the P&L diagram is only half the story. We discuss why vertical spreads often perform worse than expected prior to expiration and the role theta plays in the final payoff.

• Legging vs. Spread Orders: When should you attempt to "leg out" of a spread? Dan and Mark discuss the risks of delta exposure when breaking apart a vertical in a fast-moving market.

• Broker Routing & PFOF: How Payment for Order Flow and specific broker "spread books" (like Robinhood's) can impact your execution quality, especially in illiquid names.

• Market Maker Psychology: What determines the width of a bid-ask spread? Dan explains how volatility risk and liquidity determine the "toll" you pay to enter and exit a trade.

• Mail Call: The team answers listener questions about avoiding spreads during earnings and the rise of prediction markets (binary betting).
