Twitter Closes at IPO Price; S&P 500 Turns Negative for 2015

Twitter (TWTR) closed at its $26 IPO price after getting caught up in a tech sell-off Thursday. That social network has suffered recent deep losses following a disappointing second quarter which triggered fears of slowing user growth. It was another bruising day for Wall Street as the question of when a rate hike could occur continued to cause panic. The S&P 500 turned negative for the year as consumer and tech stocks sold off. The benchmark index is now down nearly 5% from its all-time high set in May. High-momentum movers were among the hardest hit. For example, streaming giant Netflix (NFLX) slumped nearly 8% while Apple (AAPL) fell 2%. Google (GOOGL) fell $14 a share, while Microsoft (MSFT) took off $1 a share.
