NEW YORK — Chinese social media company Weibo Corp.'s shares soared in their US market debut Thursday. Weibo was launched four years ago by Chinese online media company Sina Corp. Weibo provides a Twitter-like service that allows users to post a feed of up to 140 Chinese characters to share with others. Users can also attach multimedia, such as photos and videos, to their posts. The company has 61.4 million average daily active users, according to its filing with the U.S. Securities and Exchange Commission. Weibo raised $285.6 million, pricing 16.8 million American depository shares at $17 each. That's a smaller amount than anticipated. Weibo had projected an offering of 20 million shares priced between $17 and $19. – AP
