Hong Kong • Hong Kong stocks extended declines, threatening to derail what had been a dramatic comeback in its equity market as another slump in global tech darkened sentiment.

The Hang Seng Index (HSI) fell 1.8% by the midday break yesterday, tracking losses in the Nasdaq 100 Index overnight, with technology and pharma stocks among the biggest losers. A gauge of China stocks fell 1.6%, led by CSPC Pharmaceutical Group Ltd.

Hong Kong’s equity benchmark had advanced 5.6% in November through Monday, rebounding from its worst streak of monthly losses in 36 years. Its month-to-month turn-around — the biggest since June 2012 — has made it the world’s best performing benchmark, despite a relatively lacklustre quarterly earnings season.

After tumbling into a bear market in September, Hong Kong’s stocks have struggled to find a floor. Caught in a US-led tech sell-off, a slump in the yuan, a trade dispute between Beijing and Washington, souring sentiment for emerging markets and one of the worst years ever for stocks in mainland China, the city’s traders have barely had a moment of calm. They’ve endured declines exceeding 2% for the Hang Seng Index on 14 occasions this year, the most since 2011. Last year, drops of that magnitude happened only twice.

Last week’s better than expected results from Tencent Holdings Ltd had helped improve sentiment, bringing volatility down from the highest level since 2016. The mood was so bearish in October that investors were blindsided by a massive short squeeze at the start of this month, a reminder of how one-directional the market had become.

Yesterday’s losses show how most problems afflicting global investors in 2018 have found a foothold in the Hong Kong. Its largest companies generate the majority of their sales from a slowing China, while the city’s dollar peg ties it to tightening US monetary policy.

Meanwhile, other index and stock moves are:

Tencent, Sunny Optical Technology Group Co, AAC Technologies Holdings Inc were among the worst performers on HSI with a drop of at least 3%, while a measure of tech companies falls by the most on Hang Seng Composite Index.
