白银，又暴涨了

Group 1: Silver Market Dynamics - Recent fluctuations in silver prices have been extreme, with prices rising above $74 per ounce after a significant drop of 9% in the previous trading day [1] - Analysts attribute the initial drop to technical factors, including profit-taking and increased margin requirements, while the fundamental conditions supporting the rise, such as a weaker dollar and geopolitical uncertainties, remain intact [4] - The recent sell-off is characterized by profit-taking and year-end portfolio adjustments, but structural conditions supporting the price increase, such as supply shortages and stockpiling by countries, continue to exist [5] Group 2: Market Reactions and Trends - The increase in margin requirements by exchanges has forced some speculators to reduce their positions or liquidate, contributing to the volatility in the silver market [5] - Despite recent pullbacks, both gold and silver are expected to record their strongest annual performance since 1979, driven by strong central bank purchases and continuous inflows into exchange-traded funds (ETFs) [5] - A brokerage report indicates that the current rise in silver prices is shaped by real physical shortages, policy-driven supply constraints, and increased inventory concentration, suggesting a more permanent change in pricing and trading dynamics in the silver market [5]
