According to researchers at the Investment Company Institute (ICI), by the end of 2012 an estimated $14.7 trillion will have been under management, representing a $1.7 trillion increase over 2011 levels. The increase in this value may be due in part to the overall increase in the values of the major stock indexes in the United States, as well as very strong increases in stock prices in various key international markets. And because of the overall weakness in the U.S. dollar relative to other foreign currencies, some foreign stock prices recorded double-digit growth rates. Also in 2012, for the first time since 2008, investors contributed approximately $196 billion into mutual funds. Additionally, in 2012 investors reinvested $194 billion of income dividends and $93 billion in capital gains distributions back into the markets.
