????IPO日期：2012年2月2日

????殺毒軟件公司AVG Technologies宣布要上市時,，人們對其寄予厚望,。公司營收正在增長，很多投資者相信從估值看,，認(rèn)為該股具有吸引力,。但它上市首日即下跌18.75%，是今年上市首日跌幅最大的一只IPO股票,。

????分析師們將此歸咎于AVG面臨的激烈競爭,，賽門鐵克（Symantec）、邁克菲（McAfee）等競爭對手已經(jīng)和個人電腦制造商達(dá)成了搭售協(xié)議,，而AVG則依賴于網(wǎng)絡(luò)“免費+增值”模式吸引客戶,。還有人擔(dān)憂，AVG最成功的產(chǎn)品Safe Search缺乏合適的移動版,。IPO 完成6個月后,，該股累計下跌已經(jīng)達(dá)到了33%。

????IPO date:?2/2/2012

????Expectations were high for anti-virus maker AVG Technologies (AVG) when it announced its plans to go public. Revenues were growing and many investors believed it was attractive on a valuation basis. But the stock dropped 18.75% on its opening day, the single largest drop for any IPO this year.

????Analysts blamed the heavy competition AVG faced and noted that competitors like Symantec and McAfee had struck tie-in deals with PC makers while AVG relied on attracting customers through its online 'freemium' model. There were also concerns that AVG didn't have a suitable mobile version of Safe Search, its most successful product. Six months later, the stock was down by 33%.
