ClaimsNassim Taleb

“The only important thing about it is that I protected my clients.”

Nassim Taleb, interviewee 2009 Nassim Nicholas Taleb (Time interview) (Time)

Factual Their own work or organisation

Taleb said the only important thing was that he had protected his clients.

Mostly true True in substance, wrong in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge said resolved true; the verdict shown is the first judge's.

What would count as true or false

Judged as of 2009. True: credible records show that clients of Universa Investments (Taleb's affiliated fund or strategy) were protected during the 2008 crash, i.e. the tail-hedging funds made large gains or offset losses in 2008 as intended. Mostly true: the protection was largely delivered, but returns varied by fund or the hedge only partly offset losses. Mixed: the results were mixed across clients or funds. Mostly false: there were modest gains that did not meaningfully protect clients, or Taleb's own role was minimal and the claim overstates it. False: clients lost money in the crisis on the strategy, or the funds did not provide protection.

    “Last year proved him wildly right, and by exploiting this mental block, Universa's investors doubled their money.”
  4. E4 Black swan manager returning 23%, anticipating bear market InvestmentNews (Bloomberg News reprint) · 24 October 2011

    “Universa returned about 115 percent to investors in 2008, according to a person familiar with the matter.”

Reasoning

Newsweek (E3), an independent source, reported in January 2009 that Universa's investors doubled their money in 2008. A later Bloomberg report (E4) put Universa's 2008 return at about 115%. The WSJ (E1) reported that separate Black Swan Protection Protocol funds gained between 65% and 115% in October 2008, so the protection was delivered but returns varied by fund. The same WSJ article (E2) says Spitznagel owned and managed the fund and Taleb consulted with its traders, so "I protected my clients" somewhat overstates Taleb's direct role.
