Just because a managed fund outperformed a market doesn't mean it didn't happen by pure luck. There are lots of managed funds and most of them are not profitable. If each chooses portfolio randomly, some of them will outperform the market.
I highly doubt rustamm or anyone partaking in this discussion is remotely qualified to know whether the most successful hedge funds, including Renaissance Technologies, Citadel, or Bridgewater are successful simply due to luck.
