FAANG Era Decline - Stocks of major U.S. companies have been falling for months

According to Bespoke Investment Group, a research investment group, FAANG plus Microsoft have accounted for a quarter of the value of the S&P500 and more than half of the index's decline this year.

The only company that continues to perform well is Apple. But the giant's sales will grow only 8 percent this fiscal year and will continue to slow until at least 2024, according to estimates compiled by analysts at Bloomberg.
