Innocent families, children, and entire communities around Israel are being targeted by terrorists. Israel has a responsibility to protect its civilians from this deadly violence. SHARE if you support #Israel’s right to defend itself and its people against existential threats from terror groups. 🇮🇱

"The first beautiful thing about expectations investing is, it actually reverse engineers the process. One thing we know for sure is the price, and then you basically are asking a simple question: what has to happen for this price to make sense?"

Hey @mjmauboussin and @amaub
Another downside to using natural language terms to express probabilities.
Not only do people disagree about what these terms mean, they also treat them as additive rather than taking averages.
If people receive two numerical probability forecasts then tend to take an average (so 50% and 70% → 60%). But if they receive two verbal forecasts (likely + likely) then they tend to combine them, so that an even becomes “very likely”. A clever paper: papers.ssrn.com/sol3/papers.…

We should look at drawdowns relative to long-term volatility. In 2008, money market funds broke the buck when their values dropped to 0.90-0.95. Not much in absolute terms but a whip-out relative to their vol. Both vol (short-term) & draw-down (long-term) management are important

Our paper on the overrewarding of lucky successes is now published!
We looked at over 10k football shots landing on posts. Players who are—just—successful get more playing time and higher ratings, than those who are—just—unsuccessful.
