> Look at the concentration of the nasdaq 100--it's all huge companies. Same for the DJIA.

The nasdaq 100 is the largest companies that exist. That's why that index exists. Ditto for S&P-500.

The DJIA is also exclusively large capital businesses.

Pretty much any index out there is going to be primarily composed of the largest players in the market, that's just how these things work.

But relative to the other parts of the economy and GDP. In 1980s the biggest of companies were not so dominant relative to today.

I get that, but your statement was a little off to me. "Look at this index which tracks large companies, it's filled with large companies!" is effectively what you said.
