They loved it. Now they hate it.

Twitter IPO pricier than Facebook's

While Facebook was profitable when it went public, Twitter lost US$64.6 million in the third quarter of this year. Photo: AP

Twitter boosted its IPO price on Monday to US$23 to US$25 a share, which would give the microblogging service a market capitalisation of US$13.6 billion at the top end of the range. That would value the company at 11.8 times its estimated 2014 sales, higher than the 11.4 times price-sales ratio for Facebook.

Internet firms' dual-class shares are best avoided

Twitter and Alibaba's upcoming IPO are putting a spotlight on dual-class ownership. Photo: Reuters

When a company goes public, it must tell shareholders how it plans to govern itself. The new owners are promised a piece of the profits and a say in how the company is run. The standard arrangement for apportioning control is "one share, one vote". That is a good, tried-and-tested design, but it seems to be going out of fashion.
