Twitter originally had their price range set at $17-$20, but has recently upgraded to $23-$25 per share. They are expected to come up with the final price on Wednesday, and to begin trading the day after on the New York Stock Exchange. Some analysts are saying that this increased price range is still way below what it should be as there is a big potential for Twitter when it comes to online ads. In fact, this guy, Victor Anthony, is very bullish setting his price target for $54 a share. It is believed that Twitter is planning to be more conservative, learning the lesson from its predecessor Facebook. Facebook originally had it's IPO set at $38, and many believe that it was simply too aggressive. As a result, FB traded at a much lower price before coming up to record highs (due to strong quarterly results from mobile ads). Last heard, it was trading at $48.63, which is 30% higher than IPO price. Apart from that, Twitter is engaged in an ongoing dispute with IBM, claiming that Twitter is infringed on 3 patents held by them.
