Today's biggest winners and losers in the stock market, a look at the notable movers:
On this episode of Stock Movers:

- CH Robinson Worldwide (CHRW) shares fall 13%, the most intraday since late July, after the freight broker announced an agreement to acquire peer RXO in a stock-and-cash deal valued at about $5.8 billion. RXO shares jump 22%, the most intraday since June 2024. The deal represents a 29% premium to RXO’s closing price on Friday.

-Align Technology (ALGN) is facing renewed claims it monopolized the market for clear dental aligners, after the Ninth Circuit reversed a lower court grant of summary judgment to the company in two private cases. The US Court of Appeals for the Ninth Circuit said Monday the district court erred, as the plaintiffs in both class actions provided enough evidence that a jury could reasonably find Align inhibited competition in the aligners market as well as the market for scanners that take digital images of the jaw, teeth, and bite of a patient. Align Technology is an Arizona-based medical device company founded in 1997 that invented the Invisalign system of transparent mouthpieces used to straighten teeth. Today, the company controls a 90% share of the US market for aligners, according to the plaintiffs.

- DraftKings (DKNG) shares are up 3.9% as BofA raises the recommendation on the online sports betting company to buy from neutral, with the analyst citing her more positive view of the predictions markets (PM) impact. Analyst Julie Hoover writes that while the regulatory future of PMs remains uncertain, she believes DraftKings is “well positioned either way”. DKNG stock has unraveled more than 46% this year, but Hoover sees DraftKings' 2027 estimates as bottoming with potential for upside growth.
