On December 17, the official CHOW TAI FOOK flagship store posted a notice on its homepage indicating that, due to market factors, prices for some products would be raised on December 19. Recently, the CHOW TAI FOOK official flagship store on Tmall also posted a similar alert on its homepage, stating that some product prices would be increased soon due to market influences. This marks the third time CHOW TAI FOOK has raised product prices this year. The price adjustment in March targeted "fixed-price" gold products, with increases ranging from 10% to 20%, while the late October increase was between 12% and 18%. Citi issued a research report initiating a 30-day positive catalyst watch on CHOW TAI FOOK, forecasting strong operational performance for the third quarter of fiscal year 2026, which is expected to be announced in January, and anticipating an upward revision to the same-store sales growth guidance. Following robust performance in October and November, Citi expects that the recent price increases for fixed-price gold products will help maintain ideal same-store sales growth in December. The unexpectedly strong sales following the value-added tax policy adjustments are projected to have a positive impact on the Group's gross profit margin for the second half of fiscal year 2026 and the first half of fiscal year 2027.
