So much for Super Tuesdays. Stocks ended the day down sharply after a volatile day of trading.
The Dow Jones Industrial Average, the S&P 500, and the Nasdaq started the day deep in the red before rebounding. The Dow even briefly made it into positive territory. But all three indexes ultimately closed between 0.8% and 1% lower.
"Volatility has clearly ramped up," said Ryan Detrick, senior technical strategist at Schaeffer's Investment Research. In fact, the Dow has swung more than 100 points during six out of the seven trading days so far this month.
The market's main fear gauge -- the CBOE Market Volatility Index(VIX) -- shot up 11%, and CNNMoney's Fear and Greed Index moved closer to extreme fear. Just a week ago, that index was in neutral.

"With stocks at this level, it's not the worst thing in the world to take a breather for a month or two," said Dan Greenhaus, market strategist at BTIG.
