Adidas shares fell sharply on Tuesday after Bank of America issued a rare “sell” rating on the stock, noting that the German sneaker maker’s situation is set to become increasingly difficult. This sudden series of downgrades caused the stock to drop as much as 7.6% at one point. Analysts led by Thierry Cota forecast that the company’s sales growth would slow to single digits this year. They added that Nike’s recovery poses a potential competitive threat, while other brands such as On, Asics, and Puma may attract more attention. The bank downgraded its rating directly from “Buy” to “Underperform.”
