U.S. stock market movement: Tempus AI plunges on October 6 due to high valuation, profit-taking, and institutional reduction.

Neil J Kanatt, Reuters, October 6 - On Tuesday, shares of Mattel (MAT.O) dropped about 3% after investor Ariel Investments urged the toy maker to explore strategic options including a sale, merger, or divestiture of key assets. This move increased pressure on Mattel. Last week, the company announced CEO Ynon Kreiz would step down, which has sparked renewed acquisition interest in the company. Details are as follows: Ariel, which holds a 5.4% stake, said in a letter that Mattel’s stock remains significantly undervalued and that its portfolio could be attractive to other toy companies, entertainment firms, or private equity funds. A source told Reuters that last week, Authentic Brands—owner of brands such as Reebok, Brooks Brothers, and Guess—approached Mattel for a potential acquisition, valuing the company at around $6 billions or higher. This is the second time this year that investors have pushed for a strategic review. In May, Southeast Asset Management also urged Mattel to consider options including privatization, a sale to Hasbro (HAS.O), or selling to a media company. Mattel has faced pressures from weakened toy demand and rising tariff-related costs in recent years. The company stated it would "consider the views expressed in Ariel Investments’ letter" while "acting in the best interests of all shareholders." "The debate is increasingly focused on a central issue: are Mattel’s brands worth more inside the company or in someone else’s hands? Investors want evidence showing the company is worth more as a whole than the sum of its parts," said Brian Jacobsen, Chief Economist at Annex Wealth Management. According to data compiled by London Stock Exchange Group (LSEG), Mattel’s current share price is $15.65 and its forward price-to-earnings ratio is 10.45, compared to Hasbro’s P/E ratio of 14.35.

Latest Developments October 6th – Constellation Energy's stock price (CEG.O) surged 12.2% to $300.3. If the rally holds, this would mark the company's largest single-day gain since April 2025.
