The Lie Your Stock's Price is Telling You | Kris Abdelmessih on Why Options Hold the Truth

What can bar bets, coin flips, and the length of your subway commute teach us about options pricing? In this episode of Excess Returns, Matt Ziegler is joined once again by Kris Abdelmessih to break down complex options theory into intuitive, real-world analogies. From prediction markets to probability distributions, Kris helps us understand how the options market reveals what the stock market often hides—how investors are pricing not just if something happens, but how much it matters when it does. This is options math with a twist, taught like you’re five, but ready for Wall Street.

📈 Whether you're an investor trying to size a high-risk, high-reward position, or simply curious about how the market “thinks” about uncertainty, this episode is full of mental models you’ll want to revisit.
