 WSJ interviews Burton Malkiel 50 years after Malkiel published "A Random Walk on Wall Street," putting forward the efficient market hypothesis. That hypothesis he says is till more true than ever, that the market senses information and reflects what that information says in the stock price. This means one would do better than active investors by investing in an index that reflected the broader stock market with a wide ranging basket of stocks that reflected it. By 1974 Vanguard's Bogle started the first index fund for passive investing. It did not gain support till 2 decades later, yet today half of all US investing is in index funds. Malkiel supports the index fund investment and says equities play an important role even in retirement, and says the next decade will give returns closer to 5-6% for equities. He says the important thing is not fancy shots just hitting the ball back, not making mistakes.
