It is starting to look like Twitter's much awaited IPO is going to be hyped up even more than the Facebook fiasco. Brokers are starting to predict that Twitter's share price could almost double in its first year as a listed company.

SunTrust Robinson Humphrey analyst Robert Peck, the first to rate the stock, suggested Twitter could float at $28-$30 per share, and said it could reach $50 within a year. Peck said that it was important for investors to look at Twitter beyond just a 140 character text. Despite posting big losses over the last three years, Twitter hopes to woo investors with its advertisement revenue growth.

The company only started selling advertising only in 2010, received about 87 percent of its revenue from advertising in the first half of the year. Peck thinks that Twitter could capture a part of the $200 billion global TV market with Amplify, which allows broadcasters to show video clips and ads through tweets coordinated with what is being shown on TV.

Twitter could make use of the search capability with a product similar to Google's AdWords, where advertisers pay Google according to the number of clicks on the ads, the brokerage said. Peck based his numbers on a float of 50 million shares, raising up to $1.5 billion, taking shares on issue to around 537 million.
