Like US rival Twitter, Weibo has had a rocky entry onto the public markets.

新浪微博周四宣布今年第一季度亏损较一年前有所扩大，导致股价在盘后交易时段下跌。新浪微博是从中国互联网集团新浪(Sina)剥离出来的社交网络平台。

Shares of the Twitter-like service spun out of Chinese internet group Sina fell in post-market trading after its quarterly loss widened from a year earlier.

这是新浪微博自今年4月在纽约首次公开发行(IPO)以来公布的首轮业绩。它表示，今年第一季度，因广告销售额上升，收入增长逾一倍，至6750万美元，与华尔街预期相符。

In its first set of results since an initial public offering in New York in April, Weibo said revenues more than doubled to $67.5m, matching Wall Street's forecasts, as sales of display adverts on the social network rose.

然而，亏损扩大至4730万美元（合每股31美分），一年前为亏损1920万美元。新浪微博将其归咎于税赋的提高以及营销和员工支出的增加。

The company's loss, however, widened to $47.3m, or 31 cents per share, from $19.2m a year earlier. Weibo put that down to higher taxes as well as increased spending on marketing and staffing.

对投资者而言，新浪微博为他们提供了一个买入不断壮大的中国互联网市场的机会。

然而，上月美国互联网和科技股大幅下跌，使得尚未盈利的新浪微博不得不削减了最初的融资目标——最初的融资计划意味着它的估值能高达80亿美元。

However, the unprofitable company's ambitions to secure a valuation of almost $8bn were dented last month by a rotation out of internet and technology shares in the US, as investors sought out relatively safer stocks.

新浪微博绝大部分收入来自其网站上呈现的广告。今年3月底，新浪微博的月度活跃用户达到1.44亿，同比增长34%。用户可以在新浪微博上玩游戏和分享新闻。

The vast majority of Weibo's revenue comes from advertising on user news feeds. The micro-blog, where users can play games and share news, counted 144m monthly active users at the end of March, up 34 per cent from a year earlier.

新浪微博表示，在会计上对几个项目作调整后，一季度亏损额将缩窄至480万美元（合每股3美分），而华尔街的预测为每股6美分。

Adjusting for several items, Weibo said its loss narrowed to $4.8m, or 3 cents a share, compared to Wall Street expectations for 6 cents.

新浪微博上市时，不仅发行规模不及最初预期，发行价也处于预期低端。股价一度触及24.48美元高点后，已下挫近五分之一。

Weibo ultimately sold fewer shares than it originally hoped at the low end of expectations. After touching a high of $24.48, shares have fallen by nearly a fifth.
