Check out the companies making headlines in midday trading.

Wynn Resorts — Shares of the casino operator jumped 10% after a filing showed billionaire investor and restaurant owner Tilman Fertitta has built a passive 6.1% stake in the company. The stock is still down more than 20% this year.

Newell Brands – Shares of Newell Brands, a consumer goods manufacturer, slipped 7.3%. The company was recently downgraded by a slew of analysts including those at Raymond James, Deutsche Bank, Jefferies and Wells Fargo following their earnings report last week.

TuSimple – Shares of self-driving startup TuSimple slumped 46% after it fired its CEO, Xiaodi Hou. An internal investigation showed improper dealings and a possible tech transfer to a Chinese firm by Hou. The FBI and Securities and Exchange Commission are both investigating, the Wall Street Journal reported.

First Solar — The solar stock jumped more than 9% during midday trading. On Friday, Bank of America raised its price objective on First Solar, saying the company’s growth prospects remain intact even after its more than 60% rally this year, according to the analyst.

Paramount Global — Shares of Paramount Global shed 3.6% after being downgraded by Wells Fargo Securities to underweight from equal weight. Analyst Steven Cahall, who had just downgraded the media company to equal weight earlier this month, expects negative revisions and a possible reconsideration of sports rights or a shift in strategy from Paramount.

HanesBrands Inc — Shares of HanesBrands fell more than 4% after the retailer received a double downgrade from Wells Fargo. The firm cut the stock to underweight from overweight, citing increasing macroeconomic and balance sheet issues in the next year.

Meta Platforms — Shares of Meta Platforms fell 5.5%, leading declines in megacap technology stocks following disappointing earnings results last week. Alphabet, Apple and Microsoft all slipped about 1% as well.

Global Payments — The stock slid 6.7% after the company reported earnings that were in line with expectations on per-share earnings and beat anticipated revenue. Meanwhile, the company said it was taking steps to finance multibillion-dollar transactions that involved debt. The stock is still up about 7% this month.

Align Technology — Align Technology stock jumped 4% Monday after the company announced a new $200 million accelerated share buyback agreement under its $1 billion repurchase program.

Howmet Aerospace — Shares of Howmet Aerospace, an aerospace manufacturer, fell more than 3% Monday after the company reported quarterly results that missed Wall Street expectations for revenue.

Other chip stocks were also under pressure on Monday, with Advanced Micro Devices dipping 3.1%.

Amgen — The biopharma stock dipped 1.5% after Barclays downgraded Amgen to underweight from equal weight, saying investor enthusiasm ahead of an obesity drug update next week may be overdone.
