Amazon is understandably on the list of large-cap fund favorites, but so are Home Depot and Walt Disney, and so is Comcast (CMCA)—the only other top-five stock in the sector that’s up for the year. Starbucks and Nike are favorites of large-cap growth managers, while Under Armour is popular with mid-cap growth funds,” reports Ben Levisohn for Barron’s.

“It’s not as if there aren’t fundamental reasons for consumer stocks to underperform. Morgan Stanley strategist Adam Parker notes that the discretionary sector’s outperformance began when the Federal Reserve cut rates by three-quarters of a point in January 2008, and continued until it hiked rates for the first time in December 2015. Another rate hike would also weigh on the sector,” according to Barron’s.
