Shares of Ross Stores (ROST - Get Report)  tumbled Friday even as the discount department store giant beat analysts' earnings and revenue estimates.

The stock price of Ross, which has 1,483 stores across the U.S. and Guam, fell 2.07% to $105.18 after the chain released second-quarter earnings.

Ross executives said looming plans by the Trump administration to slap 10% tariffs on apparel and footwear made in China have forced the chain to update its earnings guidance for the remainder of the year.

Even so, Ross continues to expect a same-store sales increase of 1% to 2% for the third and fourth quarters, said CEO Barbara Rentler.

"We delivered respectable gains in both sales and earnings for the second quarter," Rentler said in a press statement.

Ross reported quarterly earnings of $1.14 a share, beating the $1.12 a share estimate of analysts surveyed by Zacks Investment Research. The results represented an earnings surprise of 1.79%, with the company having topped analyst-EPS estimates for the last four quarters, Zacks said.

Ross reported revenue of $3.98 billion for its second quarter, which ended in July, beating the estimate of analysts polled by Zacks by 0.23% and posting a gain over the $3.74 billion the discount chain generated during the same period in 2018.
