Hopium Is Waning: Expect Increased Market Volatility

 | Jan 27, 2014 07:44PM ET

Thursday, there was a relatively large price decline when stocks were sitting near a 52-week high, wiping out a week’s worth of closes. Over the past year, we’ve seen a remarkable 10 such occurrences (according to sentimentrader.com), the most in history. To be specific, these are times when the S&P 500:

  • Was within 0.5% of a 52-week high
  • In one day, lost at least 0.75%
  • In one day, closed below at least the last 5 closes

The M.O.’s really got blasted in the later part of last week, plunging down through the zero line, telling us capital is leaving the market on a net basis. The depth of and angle of the plunge are the notable items! Friday saw 91% of total volume to the down side, with a rare 6.5:1 negative a/d at the close. Often, we see this kind of breadth “overbalance” at the open of a big up or down day, which fades to less than 3:1 by the close. Friday, the breadth got worse by the hour; that’s a new thing.
