Costco Stock Shines While Consumer Staples Underperform

Lucas Downey

A gain of 12.5% in 2018 for shares of Costco Wholesale Corporation ( COST) was likely helped by bullish unusual trading activity in the stock. Costco's shares have been performing very well this year, even in the face of a weak year-to-date (YTD) performance for the consumer staples sector. With activity like that, it should come as no surprise that Costco stock has trended higher in 2018.
