THIS FREE MIT LECTURE ON MARKOV CHAINS WILL TEACH YOU MORE ABOUT QUANT TRADING THAN A 2-MONTH WALL STREET INTERNSHIP. Not a bold claim. A provable one. The algorithms running inside Citadel, Renaissance Technologies, and Two Sigma are built on this exact mathematical foundation. The quants printing money every single day did not learn this from a finance influencer or a trading course. They learned it from lectures exactly like this one. Here is why Markov Chains are the most underrated concept in quantitative finance: Every price movement is a state transition. Every trading strategy is a probability model. Every edge a quant has is built on understanding what state the market is currently in and what state it is most likely to move to next. Markov Chains are the mathematical language that describes all of it. Wall Street pays analysts $200,000 a year to understand this framework. MIT put the lecture on YouTube for free. The people who watch this tonight will understand the mathematical foundation of quantitative trading at a level most finance graduates never reach in their entire careers. The people who skip it will keep trading on gut instinct and wonder why the systematic funds are always one step ahead. One hour. Free. From MIT. This is the most productive thing you can give your week. Bookmark this before you do anything else today. Follow @cyrilXBT for more resources that build real edge.
