Align 科技公司

克雷·布莱瑟尔Buffalo Discovery基金

股票代码：(ALGN)

所属行业：科技

    Buffalo Discovery基金管理资产规模4.30亿美元，晨星（Morningstar）数据显示，过去10年该基金平均每年增长10.6%，高于同类基金的7.5%。Buffalo Discovery的联席经理克雷·布莱瑟尔相信创新无处不在，创新并不限于科技本身。

    一个很好的例子就是：Align科技公司（Align Technology）。这家隐适美（Invisalign）隐型牙箍制造商年收入5.50亿美元，给牙齿正畸行业带来了颠覆性革命。这家公司生产的这种透明隐形牙箍，可以像矫正器一样带上和取下，最初作为成人传统金属牙箍的替代品而开始流行。如今，这家公司正在进入青少年市场，这一市场占到每年260万例正畸病例的2/3。（自从成人产品发货量出现季度下滑以来，该股股价已经下跌28%，但布莱瑟尔并不担忧，因为他看好青少年市场的潜力。）布莱瑟尔相信，其基金持有的这只重仓股未来五年将继续以每年15%左右的速度增加收入，利润增速将更快。正如布莱瑟尔所言：“只要跟牙齿正畸师和牙医聊一聊，（就会发现）这是患者走进诊所唯一要求指定品牌的产品。”

Align Technology

Clay Brethour Buffalo Discovery

Ticker: (ALGN)

Sector pick: Technology

    Clay Brethour, co-manager of the $430 million Buffalo Discovery Fund (BUFTX)-- up 10.6% a year on average for the past 10 years, vs. 7.5% for its category, according to Morningstar -- likes to think about innovation broadly rather than about technology per se.

    Case in point: Align Technology, the $550 million (in revenue) maker of Invisalign invisible braces, which have transformed orthodontics. The company's clear aligner trays, which pop in and out like retainers, first became popular with adults as an alternative to the despised traditional metal braces. Now the company is making inroads in the teenage market, which represents three-quarters of the 2.6 million orthodontics cases begun each year. (Shares have fallen 28% since a quarterly decline in shipments to adults, but Brethour isn't worried because of the potential he sees in the teen market.) He thinks the company, a top holding of his fund, can continue to increase revenue about 15% or so a year, and expand profits at an even faster rate, for the next five years. As Brethour puts it, "If you talk to orthodontists and dentists, this is the only product where patients come in and ask for it by brand."
