Diageo struggles while Constellation gains hedge fund favour despite sector headwinds

Jim Cramer has shifted his stance on the alcoholic beverage sector, showing cautious optimism for Constellation Brands whilst remaining bearish on Diageo. He highlighted Constellation's new CEO, Ned Fink, as a potential catalyst for growth, noting Fink's successful track record at Jim Beam. Diageo faces multiple headwinds, including a 34.9% sales decline in China and an 8.4% drop in North American net sales. The stock has fallen 52% over five years. Constellation grew beer sales 2% to $2.28 billion in fiscal Q1, beating earnings expectations. However, beer depletion fell 0.3%, whilst wine and spirit sales dropped 10%. Hedge funds appear to favour Constellation, with 56 funds holding stakes versus 35 for Diageo. However, Diageo trades at a higher forward P/E ratio of 14.41 compared to Constellation's 11.36.

Global spirits giants sit on $22B unsold inventory amid demand slowdown

Major spirits companies are grappling with a $22 billion inventory glut, the largest in a decade, according to the Financial Times. Diageo, Pernod Ricard, Campari, Brown-Forman and Remy Cointreau are sitting on unprecedented amounts of unsold aged spirits, including whisky, Cognac, tequila and rum. The surplus stems from pandemic-era over-production when home consumption surged. However, consumer demand has since declined due to health concerns and shifts towards THC beverages. Companies have responded by pausing production at distilleries, reducing workforces and closing facilities. Cognac faces particularly severe challenges, with slowing exports and trade issues with China forcing price cuts. Even tequila, which recently outsold American whiskey in the US, is experiencing slowdown. Industry analysts warn that production cuts risk future shortages if demand rebounds unexpectedly.
