信义玻璃（00868.HK）今日盘中大涨7.11%，成为市场关注焦点。该股价格走势与港股光伏板块整体上涨趋势一致，反映了市场对光伏行业前景的积极预期。
消息面上，多晶硅期货主力合约今日触及涨停，最高报49105元/吨。自7月以来，多晶硅期货价格已累计反弹约50%。这一涨势主要受益于行业"反内卷"政策预期的强化，以及产业链价格的全面回升。作为光伏玻璃的主要生产商，信义玻璃有望从行业供需格局改善中获益。
值得注意的是，工信部近期推动多个行业淘汰落后产能，"反内卷"成为市场核心主线。这一政策背景下，玻璃行业的产能置换正在加速，供给收缩有望支撑价格。作为行业龙头，信义玻璃的市场地位和盈利能力有望进一步提升。不过，投资者也应当关注政策执行力度和宏观经济环境变化可能带来的风险。
