Went through the blog, and I liked how it breaks down something that can get pretty technical without making it unnecessarily complicated.
Delta hedging is one of those things that sounds simple until you actually try to keep the position neutral.
Option moves → delta changes → hedge changes → and suddenly you’re adjusting the hedge again.
That’s probably the part most people underestimate. It’s not a one-time hedge you put on and forget about. For smaller traders, the lot sizes, costs and constant rebalancing can make it a very different game compared to how institutions do it. Understanding the mechanics, though, definitely makes option Greeks and market-maker activity a lot easier to look at.
