Hey everyone, Sharing a breakdown today on a high-stakes operational challenge that trading desks often face on a Friday: Pin Risk. Here is the core breakdown: A stock settles just $0.01 in the money, and your risk position instantly jumps to 100. It settles $0.01 out of the money, and your position collapses to 0. In general, Delta tracks directional risk and Gamma its stability. But close to expiration, a mathematical breakdown near the strike price occurs, where Delta is no longer a smooth curve and exhibits a binary profile (and Gamma spikes, meaning Delta can change very rapidly). This creates a key operational challenge for a trading desk: the Hedging Disconnect. Basically, the desk cannot establish a stable hedge ratio, risking an unintended directional position. 🛠️ Hands-on inside the Sandbox To actually see this mathematical breakdown happen, open up the Market Risk Quantitative Sandbox inside our Classroom tab. 1. Go to the Equity Option Pricing and Risk module 2. Update the Time to Maturity field (30 days, 15 days, 5 days etc.) 3. Watch how the Delta curve sharpens into a step-function and Gamma violently spikes right at the strike price. 💬 Let's Discuss Below: If you are a risk manager reviewing this desk at 3:55 PM on a Friday, why is it insufficient to rely on a T-1 EOD Delta report to hedge this position? What are some ways this can be managed? Let me know your thoughts or share your sandbox screenshots in the comments!

Expecting energy, yields, dollar to rise and equities to fall on Monday. Here we go again...! In this highly uncertain environment, perhaps option trading strategies make the most sense.

Great news - US and Iran had struck an interim deal that is expected to extend the ceasefire and reopen Hormuz and get the oil flowing! Markets reacted - not super big moves but noticeable: - Energy down - Yields down - Equities up The risk though is if Iran says something unexpected that puts the deal at risk. Volatility looks to remain though market looks cautiously optimistic. Thoughts anyone?

Hi Everyone! I am currently looking to transition into a risk role within a macro hedge fund and would greatly value any insights from those with experience in this space. Given the unique nature of macro strategies—often driven by broad economic shifts and thematic positioning—how should a candidate best prepare to demonstrate their value?

You’re on the desk. A trader tells you their VaR is jumping because of a single data anomaly, not actual risk. What’s your first move? Let's discuss in the comments below 😃
