Nike in June cut its fiscal 2025 guidance, expecting a mid-single-digit percentage decline in sales, compared with analysts' forecast of a 0.9% increase. The June financial results caused the company’s stock price to drop 20%, the biggest one-day decline since 1980.

The company also said it produced 469,796 vehicles and deployed 6.9 GWh of energy storage products in Q3.

Tesla is scheduled to post its Q3 financial results after the market close Oct. 23.

Tesla stock is down 0.33% year-to-date, while the S&P 500 Index is up more than 20%.

Humana slumps on drop in quality ratings

Humana slumped more than 17% after a drop in rating for one of its major Medicare Advantage plans.

According to data from the Centers for Medicare and Medicaid Services, only around 1.6 million members, or 25%, are now enrolled in Humana’s Medicare Advantage plans with ratings of 4 stars or higher, a decline from 94% in 2024.

This drop is due primarily to the downgrade of its H5216 plan, which covers about 45% of Humana's MA members. The plan’s rating fell from 4.5 stars in 2024 to 3.5 stars in 2025.

More Wall Street Analysts:

Medicare Advantage plans receive star ratings from CMS. A drop in ratings reduces a plan's appeal to potential enrollees and can lead to lower bonus payments from the government.

Humana is the Louisville, Ky., health insurer.
