稀土是不可再生的重要战略资源，是高科技领域多种功能性材料的关键元素， 新形势下全球制造业或将逐步分化，稀土资源的战略地位有望大幅提升，稀土 价格有望迎来历史性拐点，建议重点关注新形势下稀土板块的战略配置价值。
我们判断，4 月份美国商业原油库存将创历史新高，若OPEC 及G20国家在5 月份按计划量减产，并且部分北美洲和欧洲国家“复工”，则4 月底-5 月初或为油价的底部区间。若“复工”晚于预期，OPEC 和G20 减产执行率过低，库存可能在5-6 月份饱和。最近两周，受到医用聚丙烯如口罩等产品需求大幅增长的影响，聚丙烯、丙烯、线型低密度聚乙烯等价格出现上涨。因熔喷布扩产周期较长，短期内其他聚丙烯及聚乙烯产品无法替代熔喷布，部分不符合要求的“熔喷布”进入市场。随着国内对违法商品的打击，聚丙烯拉丝料及线型低密度聚乙烯等产品价格有望回落。
Quartz word is derived from querkluftertz, an old German word which means whitish vein quartz. The word Quartz is also derived from ancient Greek word krustallos, which means, ice, because it was believed that the quartz is ice which never melts. The Sumerians cut and carved several quartz stones and used them as a cylinder seals and ring seals. The Egyptians made beads, scarab figures, and other jewelry from quartz stones. Quartz is a hard, crystalline mineral which consists of silicon and oxygen atoms. These atoms are linked with each other to form SiO4 silicon–oxygen tetrahedra. The global quartz report focuses on revenue generated from various quartz material as well as end-user industry utilizing quartz including electronics & semiconductor, solar, buildings & construction, medical, optics and telecommunication and other. Moreover, the report analyzes the current market trends of Quartz in different regions and suggests the future growth opportunities by analyzing government regulations & policies, thereby further increasing the consumer acceptance of Quartz. The factors driving the growth of the market includes increasing use of Quartz in end-user industries such as alumina, pulp & paper, soap and detergent, water treatment, and others. In addition, with rise in the chemical industry, the demand for Quartz is expected to increase significantly, as it is used in manufacturing of organic and inorganic chemicals.
