5 hedge funds I'm not sure would make a lot of sense, too small a number to diversify, funds wind down.
The hedge funds were winning for the first few years with the crisis. A straight up stock market is not great for the hedge fund side.
Also worth noting that Buffett is an active manager and claims he could beat the S&P by a large margin if he was managing a smaller portfolio. And he's said the efficient market theory is dumb and makes his job easier. He tells people to put their money into index funds and then does the opposite. From his perspective he's talking his own book, if there is another Warren Buffett level talent out there, no need to tell everyone to find the best competition and back him, might as well tell people they're wasting their time, just buy the index.
