This means hedge funds can no longer produce alpha in aggregate.  Replication has been claimed to remove the illiquidity, transparency and fraud risk associated with direct investment in hedge funds.  With the belief that the pursuit of alpha is a zero-sum game, more investors are looking to simply add "Hedge Fund Beta" to their portfolio.  These early investors have been rewarded as the replicators outperformed their direct investment cousins in 2008 due to their greater liquidity and lower use of leverage.
