The European initial public offering barometer, a monthly survey of investor sentiment, has dropped to an all-time low, as initial public offerings flounder in volatile markets. However, institutions' appetite for credit has soared to the same highs as May 2007.

The IPO barometer, complied by Frankfurt-based research company Sentix, shows both institutional and individual sentiment has fallen to a record low of -50, with individual investors feeling the most negative about initial public offerings.
