Companies to Watch: Dollar General sales soar, GUESS tops expectations, Apple earnings estimate cut by Nomura

Here are the companies the Yahoo Finance team is watching for you today.

Dollar General's (DG) stock just got more expensive. The discounter posted a big earnings beat this morning. Same-store sales were up 4%, nearly double the estimates, with strength in nearly all departments. Dollar General is also raising its outlook, despite new tariffs eating away at its profits.

GUESS (GES) posted huge beats last quarter on the top and bottom lines. Management also raised its guidance for the full year, voicing optimism on the holiday season. The CEO praised the company's "direct to consumer" business, including stores and e-commerce. European sales stood out the most, which rose 9.1%.

Nomura is cutting its earnings estimates for Apple (AAPL) because of uncertainty about the future of 5G. There are concerns about the overall demand for iPhones, especially devices that are 5G capable. The group still isn't entirely sold on other offerings like Apple News Plus, TV Plus, the Apple card and the Apple Arcade.

Tesla (TSLA) owners in California can now purchase car insurance through the electric automaker. Elon Musk announced in April that Tesla would be rolling out insurance that would allegedly save Tesla owners as much as 30% on their rates. It is unclear if this will save customers money given the Model S is already the most expensive car to insure, according to the Insurance Institute for Highway Safety.

UBS's (UBS) CEO is putting some concerns to rest. Sergio Ermotti has unveiled a new layout, naming a former Credit Suisse banker as the new wealth management co-head. Ermotti shuffled around the top of the wealth management division, appointing a number of new heads. This is the second reorganization of this division since 2018 when the firm merged the U.S. and international divisions into a single business.
