3月4日，中国管业（00380.HK）一度大涨超40%，截至发稿，公司涨22%，报0.122港元/股，市值1.63亿港元。
消息面，昨日中国管业发布盈利公告，预计去年公司权益持有人应占溢利显著增加，介于约8400万港元至8900万港元，相比上一年度经审核溢利约5840万港元明显大幅攀升。
对此，公司表示，净利润的增长源于公司营收增长、产品组合提升及更具成本效益的采购做法所致。
资料显示，中国管业主要从事管道及管件的批发、零售，隶属建筑材料行业，主要于港澳地区开展业务，亦在中国内地及亚洲其他部分地区积极寻找业务发展机会。
鉴于当前展业地区有限，中国管业营收规模相对不大，利润波动。且所处行业在当前市况下较难获得高估值。因此股价已多年低于1港元，交投相对清淡。
而由于股价基数较低，因此较小的上涨金额即可产生较大的涨幅。公司股价今日最高触及0.146港元，上一收盘价则为0.100港元，而涨幅则高达46%，截至目前成交金额不足160万港元。
