USI Corporation (1304.TW) stock: Winston Score, insiders and Congress trades
USI Corporation is a major Taiwanese company that makes petrochemical and plastic products. Its core products include polyethylene, ethylene vinyl acetate (EVA), and other chemical materials used by manufacturers of packaging, electronics, footwear, and construction goods. USI is one of Taiwan's oldest and largest petrochemical producers, with roots going back to the 1960s. The company earns revenue by selling bulk chemicals and plastic resins, primarily to industrial customers across Asia. USI also holds significant investments in other companies, including stakes in Asia Polymer and China General Plastics. Its scale and long-established supply relationships give it a solid position in Taiwan's petrochemical supply chain. However, the business faces pressure from thin margins, cyclical swings in petrochemical prices, and growing competition from larger producers in mainland China and the Middle East, making a sustained return to profitability a key challenge ahead.
