In its recently released study entitled “Sizing the 2010 Hedge Fund Universe” (Study), software and services provider PerTrac analyzed information from ten leading global hedge fund databases to identify trends with respect to assets under management, domicile, currency and performance information reporting by single manager hedge funds, funds of funds and commodity trading advisors.  The Study generally found that the overall number of entities that existed and reported performance information to databases increased during 2010 over 2009, but that the growth was unevenly distributed among the types of entities under analysis.  Moreover, the Study highlighted the significant number of small managers, and thus, from a regulatory perspective, implicitly emphasized the increased importance of state-level hedge fund adviser registration.  See “Connecticut Welcomes You! Federal Financial Regulatory Reform Restores Connecticut’s Authority over Hedge Fund Advisers,” Hedge Fund Law Report, Vol. 3, No. 30 (Jul. 30, 2010).  This article summarizes the key findings of the Study.  Also, where relevant, this article includes links to other articles in the Hedge Fund Law Report offering concrete guidance to managers on the legal and regulatory implications of the business trends identified by the Study.  See, e.g., “Who Should Newly Registered Hedge Fund Managers Designate as the Chief Compliance Officer and How Much Are Chief Compliance Officers Paid?,” Hedge Fund Law Report, Vol. 4, No. 7 (Feb. 25, 2011).
