About 86% of the money came from Institutional investors -- $18.32 billion; individual investors contributed $2.94 billion.
This sort of data is always tough to draw conclusions from: We know there is a record amount of cash in Money Markets, but the tough question is why?
I can think of many reasons -- none of which have any quantitative support:
• Hugely profitable, cash rich corporate earnings gotta sit somewhere;
• Skittish investors don't believe the rally, leaving money "safe;"
• Big bonus pools/high earners cash not put to work yet;
• The ongoing option backdating scandal continues to plague investor confidence;
• There's always been huge cash on the sidelines, even thru the 1990's bull market;
iMoneynet, the source of this data, expects to see this cash hoard continue to rise into 2007.
Is this pile of cash significant? That is an interesting question, and one I simply do not know the answer to...
