Twitters IPO road show didnt get off the greatest start, but an updated S-1 filing Monday rose the companys stock price, which is good news for investors. Twitter raised its stock price range to between $23 and $25 per share when it finally hits the New York Stock Exchange this week, giving the social media messaging platform a total $17 billion valuation. The new price is up significantly from the original $17 to $20 per share Twitter had listed. Twitter believes it will be able to defend itself in court, or find a suitable settlement with IBM, but cautions investors that you can never be too sure about these things and legal fights always cost piles and piles of money.
