  • measure expected risk and realized risk
  • e.g. if you expect a loss on a big day to be -2%, but you're losing that every other day, then there is a big difference and you should scale it back
  • the way you're thinking about risk may be wrong or incomplete
  • if they actually had good risk management, you'd never hear about them, they'd never be in the news
  • you should have a volatility measure e.g. MA of standard deviation or ATR e.g. tomorrow this could move +/- 1% and incorporate this into your risk
  • with vola sizing, the less volatile the bigger your position size, but the problem with vola is that when it is lower it has a tendency to spike back up quickly
  • so the solution is to not only look at recent vola, but vola over the past few years, and set a limit for how big it can e.g. spike 10% in a day in nightmare scenario in the past
  • his step #1: size your positions according to how much risk there is in the overall market/instrument you're trading
  • book recs: When Genius Fails, Against the Gods
  • your risk should be even on a really, really, really bad day you wouldn't be tempted to turn it off
