For most of 2023, the stock market's gains had been all about seven companies.
Market breadth, or the measure of advancers against losers, had been negative heading into June, as most of this year's rally was due to just seven companies.
Prior to June, the index's positive performance was completely due to the performance of just seven companies: Apple, Microsoft, Nvidia, Meta, Amazon, Tesla and Alphabet, counting both the Google parent's Class A and C shares.
Of that group, some 150 are higher by at least 10% and 70 have gained at least 20%.
On the downside, 108 stocks are off at least 10% and 32 have fallen at least 20%.
