Twitter shares increased by 9.2 per cent on Monday to reach the highest level since its initial public offering (IPO) following a number of product announcements.
Reuters reports shares rose to US$49 in mid-day trading, with Twitter having mostly traded in the low-$40 range since the announcement of the IPO. Shares had fallen last week after five investment banks involved in the IPO published mixed reviews of the stock.
Twitter last week began allowing individually-tailored advertisements on Twitter, based on websites previously visited by a user, which it expects to result in more advertising revenue.
HumanIPO reported last week it had linked up with Singapore-based startup U2opia Mobile to make its service available to users in emerging markets on phones without internet access through a text-only version.
Twitter said in September it would begin introducing and removing more features, sometimes on a daily basis.
HumanIPO reported last month Twitter had launched a media website dedicated to best practices on the social networking site, seeking to allow government, news websites and non-profits among others how to increase their impact through Twitter.
The company, however, gave up on its experiment to allow one user to direct message another even if they are not following each other after a restricted pilot.
