It's true that today's top 5 stocks - known by the acronym FAAMG - have largely outperformed most other stocks. That's how they became today's top 5. Over time, stock indices have typically been driven higher by a small number of stocks. And over time, those leaders have continually changed. This is the story of the stock market. Only one of today's top 5 was also in the top 5 in 2013. At the height of the tech bubble in 2000, the top 5 were companies like GE, Exxon, Pfizer, Citigroup and Cisco.
Right now, most stocks are doing fine: an index in which non-FAAMG stocks have a 99% weighting closed at the second highest level in its history today. It's on pace for a 10% gain in 2018.
