Stock Market Going Which Direction?

Patterns: Only twice before have the stock markets zoomed parabolically to such heights in less than a year as it has this time (80% up from March 2009 to April 2010). There was a 112% run-up in 1932 – which was followed by a 40% drop. And in 1933 a 116% increase was followed by a 34% drop. If this pattern is followed the S&P could be in for a 20 to 30% drop.  (http://www.businessinsider.com/david-rosenberg-heres-ten-us-leading-indicators-that-are-rolling-over-2010-5)
