U.S. Stocks End Volatile Session Lower

The U.S. stock market suffered big swings in opposite directions amid high volume on Tuesday, ending the day at session lows. Analysts pointed to cross-asset volatility, especially fluctuations in the dollar and the oil price as the culprits for wild swings on Wall Street. Initial turmoil began with Russian ruble's plunge, despite central bank's hiking of the rates to 17% overnight. Oil prices began the day with a big loss, only to settle roughly flat. The S&P 500 ended 17 points, or 0.9%, lower at 1,972.77, recording more than 2% drop from top to bottom on Tuesday. The Dow Jones Industrial Average lost 112 points, or 0.7%, to 17,069. The Nasdaq Composite ended the day with a loss of 57 points, or 1.2%, at 4,547, as technology stocks sold off.
