The Corona Crisis is Not a Black Swan: Nassim Nicholas Taleb (Universa Inv. & NYU Tandon)

Corporate Socialism: The Government is Bailing Out Investors & Managers Not You
(With Mark Spitznagel)

Why should we spend taxpayer money to bailout companies who spent their cash (and often even borrowed to generate that cash) to buy their own stock (so the CEO gets optionality), instead of building a rainy day buffer? Such bailouts punish those who acted conservatively and harms them in the long run, favoring the fool and the rent-seeker.

Die Corona-Pandemie ist kein schwarzer Schwan: Warum 2020 nach Nassim Taleb nicht mit 2008 zu vergleichen ist

Our research did not use any complicated model with a vast number of variables, no more than someone watching an avalanche heading in their direction calls for complicated statistical models to see if they need to get out of the way.

Corporate Socialism: The Government is Bailing Out Investors & Managers Not You (Medium)

Why should we spend taxpayer money to bailout companies who spent their cash (and often even borrowed to generate that cash) to buy their own stock (so the CEO gets optionality), instead of building a rainy day buffer? Such bailouts punish those who acted conservatively and harms them in the long run, favoring the fool and the rent-seeker.

Mark Spitznagel on the Coming Market Crash

“No Longer Tethered to the Fundamentals”: A Nassim Taleb Protégé on How to Prepare for the Coming Market Crash

Working with the economist (and his former professor at NYU) Nassim Nicholas Taleb —the author of the 2007 best seller, The Black Swan (Spitznagel is working on new book, Safe Haven: Investing for Financial Storms, for which Taleb is writing the foreword)—as an adviser, Spitznagel’s hedge fund has come up with a strategy to help big investors—for instance pension funds and endowment funds—protect their portfolios against the coming correction.
