FYI: This year, once again, five big technology stocks -- Facebook, Amazon, Apple, Netflix and Google parent Alphabet -- have been rising quickly, on average three times as much as the rest of the market. And that's raised the fear that individual investors are rushing into tech stocks at highs in what could be a replay of the late 1990s bubble. It's also brought up concerns about another phenomenon many money managers like to warn about -- passive investing. As more investors put their money in indexes, dollars are herded into the same stocks, with an increasing percentage going into the ones that are rising the most.
