Stocks making the biggest moves premarket: Ulta Beauty, Walmart, Cisco Systems and more

Check out the companies making headlines before the bell. Ulta Beauty — Shares of the beauty retailer popped a whopping 13% in premarket trading after a regulatory filing revealed that Warren Buffett’s Berkshire Hathaway took a stake worth $266 million in the second quarter. The bet is relatively minor for Berkshire, whose equity portfolio is worth more than $300 billion, so it’s possible Buffett lieutenants Ted Weschler and Todd Combs are behind the stake. Walmart — The stock surged 7% after the retailer surpassed Wall Street’s top-and-bottom line expectations and lifted its full-year guidance, citing healthy consumers. The company posted adjusted earnings of 67 cents per share on $169.34 billion in revenue. Cisco Systems — Shares gained 6% after the networking company topped Wall Street’s fiscal fourth-quarter estimates and announced plans to layoff 7% of its workforce. The company said it is undertaking a restructuring plan that will contribute to $1 billion in pretax charges to its financial results. Tapestry — The owner of Coach and Stuart Weitzman saw shares rise 5% on strong quarterly results. Earnings came in 4 cents above estimates. Tapestry also topped revenue estimates.

Pershing Square had more than 3 million shares of Nike at the end of the June, according to a securities filing. Snowflake — The cloud stock slipped 4% on the back of a Wells Fargo downgrade to equal weight from overweight.

Net income of 24.27 billion yuan missed the 26.91 billion yuan consensus estimate. Deere — The manufacturer of agricultural machinery rose 2.5%. Deere topped Wall Street’s fiscal third-quarter estimates, posting earnings of $6.29 per share on $11.39 billion in revenue. That surpassed the $5.63 per share on $10.84 in revenue expected by analysts polled by LSEG.
