Rally In Jeopardy?

After a suspicious reversal to the downside yesterday, Wednesday, May 23, the market again opened to the upside on a strong durable goods number and continued to add to gains as the strong new home sales data was released at 10. These gains quickly reversed. This is day 2 of a heavy market. Because of the market momentum I would expect a much more volatile market, very similar to the nineties, to start to emerge. This would mean more buy on the dip mentality rather than an abrupt end to the rally. It should be noted that Greenspan had to open his mouth from retirement to voice his concern about the unsustainable move in the Chinese stock market, almost an "irrational Exuberance" repeat. The IBD notes 5 distribution days for the Nasdaq over the past month so this rally certainly has its cracks. I would look to raise some cash if the market can't prove itself into the close. No more than 10% should be necessary at this juncture.
