IPO日期：2012年4月19日

    2012年大数据引人注目，Splunk藉此东风完成上市。这家公司致力于为美国银行（Bank of America）、康卡斯特（Comcast）等客户搜索和处理海量数据，提供宝贵洞见和可靠数字。

    虽然此前这家公司尚未盈利，属于一家名不见经传的B2B初创企业，但它4月份登陆纽交所（NYSE）的首日表现堪称亮丽。上市首日股价飙升达109%。交易量如此之大，甚至引发了纽交所旨在遏制股价剧烈波动的临时停牌机制。IPO 完成6个月后，Splunk股价较IPO仍有高达85%的涨幅。

    IPO date: 4/19/12

    Big data made a big splash in 2012, and Splunk (SPLK) was there to take advantage of it. The company searches and processes large amounts of data for clients like Bank of America and Comcast, providing them with valuable insights and hard numbers.

    Even though it was an unprofitable, little known business-to-business startup at the time, it had an explosive debut on the NYSE in April. Shares shot up 109% on their first day. Trading in the stock was so intense, it tripped an NYSE circuit breaker put in place to curb volatile trading. Six months after the IPO, Splunk shares were still up an impressive 85%.
