    Good places to look for +EV: 1. The idea is hard to backtest 2. The data is hard to acquire 3. A known input can be transformed into something novel or hard to compute. 5. The idea is known, but has only been applied to one specific area or time horizon. 1/n

    1. Bayes Adapt or get rekt. 2. Information Theory Kelly is cool, but don't skip Shannon. 3. Game Theory Markets = Nash equilibria under constant attack. 4. Tail Risk Reality isn’t normal. Mandelbrot > Gauss. Have a great weekend 🫡

    In law school, we were taught to prepare case briefs/ exam answers using a structure called FIRAC. Facts, Issue, Ratio, Analysis, Conclusion. After spending some time this weekend going over some of @therobotjames trading threads, I sketched out a structure for trading edges. 1/n
