The S&P energy index lost 1.7 percent as Brent crude oil futures fell to their lowest level in 15 months. Noble Corp was the biggest loser among the S&P energy names, falling 3.3 percent, while Ensco PLC fell 3.1 percent. Home Depot Inc shares were the worst performer in the Dow industrials, falling 3 percent to $90.16 a share after CNBC reported that hackers may have stolen credit-card data.
(Reuters) - Home Depot Inc said on Tuesday it was working with law enforcement to investigate "some unusual activity" related to customer data but that it could not confirm if it had become the latest retailer to be hit by a large-scale security breach. "At this point, I can confirm that we’re looking into some unusual activity and we are working with our banking partners and law enforcement to investigate," Home Depot representative Paula Drake wrote in an emailed statement to Reuters. "If we confirm that a breach has occurred, we will make sure customers are notified immediately." The statement came after security website KrebsonSecurity first reported that multiple banks had seen evidence that Home Depot may be the source of stolen credit and debit cards put up for sale on underground markets. Retail customers faced a massive data breach during last year's holiday season when hackers stole at least 40 million payment card numbers and 70 million other pieces of customer data from Target Corp .
By Alwyn Scott NEW YORK (Reuters) - Boeing Co shares slipped 1.3 percent on Tuesday after a pair of downgrades from highly ranked analysts, including one who cut the stock outlook to "underperform." The underperform rating by The Buckingham Research Group, a New York-based broker-dealer, marked the first such rating for Boeing's stock since 2009, according to data by Thomson Reuters. In 2009, Boeing was suffering from delays in bringing its 787 Dreamliner to market. Buckingham also cut its price target for Boeing shares to $101, well below the current price of over $125. Analyst Richard Safran, ranked third among 23 Boeing analysts for estimate accuracy and recommendation performance, wasn't immediately available for comment.
