Just over a year ago, in one simple graphic, we showed why Bridgewater, which currently manages around $150 billion, is the world's biggest hedge fund. Quite simply, its flagship $80 billion Pure Alpha strategy had generated a 16% annualized return since inception in 1991, with a modest 11% standard deviation - returns that even Bernie Madoff would be proud of. And, true to form, according to various media reports, Pure Alpha's winning ways continued in 2013, when it generated a 5.25% return: certainly underperfoming the market but a respectable return nonetheless. However, Pure Alpha's smaller cousin, the $70 billion All Weather "beta" fund was a different matter in the past year. The fund, which touts itself as "the foundation of the "Risk Parity" movement", showed that in a centrally-planned market, even the best asset managers are hardly equipped to deal with what has largely become an irrational market, and ended the year down -3.9%.
