The ups and downs
AP:
The Dow Jones industrials, down more than 323 points in earlier trading, ended the day with an advance of just under 300 points…”Volatility is certainly the norm now and not the exception,” said Art Hogan, chief market strategist at Jefferies & Co. “We have had 14 trading days so far this year and only two of them have been without a triple-digit swing. Three of those days have had 300-point swings.”
Note the large discontinuities between the end of one trading day and the beginning of the next in the chart above. Disconcerting times.
