Hong Kong's economy grew by 1.8% in Q3 compared to the same period last year, marking the slowest pace in five quarters, according to advance estimates from the Census and Statistics Department. This figure is down from a revised 3.2% growth in the previous quarter and below economists' forecast of 3.1% from a Bloomberg survey. The slowdown is attributed to weakened exports and reduced private consumption, with export growth falling to 3.9% from 7.5%. The Hang Seng Index fell over 816 points, and automotive stocks declined after the European Union implemented tariffs of up to 45.3%. Meanwhile, China's manufacturing activity expanded for the first time in six months, with the purchasing managers' index rising to 50.1 in October.
