The Facebook IPO is set for May 17, 2012. I was curious about how the general market reacted after the last mega IPO for Google. Here are the comparative charts starting in August 2004 until Google peaked out along with the indices.
With the current market in a defensive mode, the old adage to "Sell in May" may not apply this time around. The MCO and SUMmation Index are moving slowly towards a buy configuration and the Facebook IPO may be the catalyst.
