????共享式租車服務(wù)公司ZipCar上市后一周股價(jià)漲幅已超過60%,。對(duì)于一家在2009年至2010年虧損額擴(kuò)大近兩倍的公司而言，這樣的漲幅相當(dāng)可觀,。

????事實(shí)是企業(yè)不一定要盈利,，才能上市。

????今年以來,，已有19家獲風(fēng)險(xiǎn)資本支持的企業(yè)在美國的證交所完成IPO定價(jià)，其中12家是未盈利企業(yè),，包括日前發(fā)行額達(dá)9,200萬美元的Sagent Pharmaceuticals,。

????但總的來說，盈利企業(yè)在IPO及上市后股價(jià)表現(xiàn)方面都優(yōu)于未盈利企業(yè),。平均而言,，盈利企業(yè)單筆IPO募資規(guī)模1.08億美元，截至發(fā)稿前一日收盤,，二級(jí)市場(chǎng)股價(jià)較發(fā)行價(jià)上漲25.23%,。而未盈利企業(yè)(不包括日前首日上市交易的Sagent)的單筆IPO募資規(guī)模8,800萬美元，股價(jià)上市以來漲幅僅略高于9%,。若考慮到Sagent,，最后一個(gè)數(shù)據(jù)可能會(huì)略有上升，但升幅不會(huì)太大——截至發(fā)稿,，Sagent股價(jià)上漲約19%,。

????而且，股價(jià)漲幅最大的是中國殺毒軟件生產(chǎn)商奇虎360科技,；該公司去年實(shí)現(xiàn)凈利潤近850萬美元,，營業(yè)收入5,700萬美元。股價(jià)較IPO價(jià)格14.50美元/股已上漲近135%,。

????下面列出了全部19家企業(yè)的IPO價(jià)格,、最近股價(jià)及IPO募資規(guī)模 (標(biāo)紅的是非盈利企業(yè))：

????In the week since car-sharing service ZipCar (ZIP) went public, its stock has climbed more than 60%. Not too shabby for a company whose losses nearly tripled between 2009 and 2010.

????The reality is that companies do not need profits to go public.

????So far this year, 19 VC-backed companies have priced IPOs on U.S. exchanges. Twelve of them were unprofitable, including yesterday's $92 million offering from Sagent Pharmaceuticals (SGNT).

????In general, however, profitable issuers have more successful IPOs and after-market performance. On average, they raised $108 million and were trading 25.23% higher than their offering prices as of yesterday's market close. The unprofitable issuers (minus Sagent, which began trading today) raised around $88 million, and were up just over 9%. That last figure will rise a bit once Sagent is taken into account -- it's up around 19% as of this writing -- but not by too much.

????Moreover, the largest percentage gainer is Qihoo 360 Technology (QIHU), a Chinese maker of anti-virus software, which reported nearly $8.5 million in net profit last year on $57 million in revenue. Its shares are up nearly 135% from its $14.50 per share IPO price.

????Here's the full list (unprofitable companies in red):
