Yikes! Apple Had a Crap January

January was the worst month in a very long time for Apple stock.

How bad was it?  At the close of trading Thursday, Apple shares had lost more than 14 percent of their value since New Year's Day. That kind of monthly loss has only happened to the Cupertino powerhouse three other times in a decade. The last time? September 2008.

But really, that doesn't fully capture the impact of the stock's tumble. That's because while Apple tumbled, the broader markets were having a banner start to the year, with the Nasdaq up 4.1 percent and the S&P 500 up 5 percent.

How unusual is that? Since the year 2000, there had never been a month when Apple lost more than 14 percent while the Nasdaq rose. There had been only one month when Apple lost more than 14 percent while the S&P rose, back in May 2001, but that was a half a percent.
