Taiwan Weighted Index Plunges 2.67% on Broad Sector Weakness

Summary
Taiwan's benchmark stock index recorded a significant decline at Monday's close, dragged down by heavy losses in the plastic and energy sectors. The Taiwan Weighted fell 2.67% amid a volatile session for global commodities.
Taiwan's benchmark stock index, the Taiwan Weighted, fell sharply to close Monday's trading session, dropping 2.67% amid broad-based selling pressure. The decline was led by significant losses in the nation's plastic, oil, and gas sectors, according to market data.
Market Performance at the Close
The downturn reflected a risk-off sentiment among investors, with widespread losses across key industrial segments. Data reported by Investing.com showed that the Plastic and the Oil, Gas & Electricity sectors were among the primary drivers of the index's negative performance.
This broad sell-off suggests that macroeconomic concerns or sector-specific headwinds weighed heavily on the market during the session.
Individual Stock Movers
Several individual stocks experienced steep declines, with some hitting near-limit-down levels. The day's worst-performing stocks on the index included:
Ad- Spirox Corp (TW:3055), which fell 9.97% to 135.50.
- Formosa Sumco Technology Corp (TW:3532), which declined 9.96% to end at 379.50.
- Ampoc Far-East Co Ltd (TW:2493), which was down 9.96% to 212.50.
In contrast, a few companies bucked the negative trend to post strong gains. AVer Information Inc (TW:3669) surged 10.00%, while Chung Fu Tex-International Corp (TW:1435) and Sino Horizon Holdings Ltd (TW:2923) rose 9.95% and 9.93%, respectively.
Broader Market Context
The equity market slump occurred alongside significant volatility in global commodity markets. Crude oil futures for September delivery were down more than 5%, while gold futures posted a modest gain, a typical move toward safe-haven assets during periods of market uncertainty.
In foreign exchange markets, the New Taiwan dollar weakened against the U.S. dollar. The USD/TWD currency pair was up 0.17% to 32.39, indicating pressure on the local currency.
