Twitter Shares Start Sliding

After amazing first day


Shares of the microblogging service Twitter are down 3% in morning trading following its impressive debut last week on the New York Stock Exchange.

The stock is trading at $40.50 after a fast start on its first day on Wall Street last Thursday when Twitter shares soared 73%. The company closed the week with a 7% dip on Friday.

The launch of Twitter's IPO has generated a new wave of millionaires and billionaires, including co-founder Evan Williams, whose stock would be worth more than $2 billion.
