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?"

Thanks @mjmauboussin for the timeless Expectations Investing, one of my all-time favorites among investing books. Covering most of what an investor need to know. Find my review @Investbythebook

How investors can take advantage of behavioral inefficiencies:

1. Be Mindful Of Sentiment And Overextrapolation
2. Rely On Valuation
3. Lean On Facts
4. Timing
5. Listen To Benjamin Graham

25iQ Terms of the Day: "Profit pool: the distribution of an industry’s value creation at a point in time. The horizontal axis measures size, typically invested capital or sales as a percentage of the industry, and the vertical axis measures profitability."https://t.co/ifMHQtDgKb

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.

[Artur Sepp: Systematic Quant Trend/Vol/Rates/Macro @ArturSepp]

@Stefano_Peron 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.
