Inflow and outflow data for the biggest exchange-traded funds offer investors an insider’s look into where other investors are putting their money. CNBC’s Bob Pisani breaks down where investors are betting their money: China, anti-inflation and financial stocks.

As reported by CNBC, gold is the most popular exchange-traded investment. In the first quarter alone, gold funds accepted $12 billion in additional investor capital, making it the number one investment in 2009. Were the SPDR Gold Shares (GLD: Quote, Profile, Advanced Chart, News) to be ranked against the biggest holders of gold in the world, it would rank at number 6, above the country of Switzerland and below Italy, which currently holds about twice as much gold.

Inflation protected Treasuries are also a popular play on Wall Street after receiving little attention for years. The iShares Barclays TIPS Bond Fund (TIP: Quote, Profile, Advanced Chart, News) drew $2.3 billion to swell to $12 billion under management.

Emerging market funds round out the list of most popular investments after iShares MSCI Emerging Markets ETF (EEM: Quote, Profile, Advanced Chart, News) collected $1.5 billion in the first quarter alone.

Credit Agricole Structured Asset Management (CASAM) has been given the reins to develop an exchange-traded fund based on the successful Dow Jones EURO STOXX 50 Index. A GlobeNewswire press release reports that the previously mentioned index launched early in 1998 and has since grown by more than 188%. EURO STOXX 50 Index is made up of 50 supersector leaders among twelve European countries, such as France, Germany, and Italy. Valerie Baudson, Managing Director of ETF Development at CASAM, is quoted in the release, saying, “With the launch of our ETF on the Dow Jones EURO STOXX 50, we offer our clients simple, liquid and transparent access to equities in the euro zone.” The index offers investors an intelligent benchmark to European stocks, according to Werner Burki, chairman of STOXX supervisory board. The upcoming ETF is due to trade on the NYSE Euronext Paris platform.

With the American Stock Exchange (AMEX) completing its merge with the NYSE Euronext, Northern Trust Global Investments (NTGI) will be transferring six of its NETS brand ETFs to the new united exchange. PRNewswire identifies the six ETFs that had been trading on the AMEX and will be making the move. These ETFs are: NETS FTSE 100 Index Fund (UK) ETF (LDN: Quote, Profile, Advanced Chart, News), NETS DAX Index Fund (Germany) ETF (DAX: Quote, Profile, Advanced Chart, News), NETS S&P/ASX 200 Index Fund (Australia) ETF (AUS: Quote, Profile, Advanced Chart, News), NETS S&P/MIB Index Fund (Italy) ETF (ITL: Quote, Profile, Advanced Chart, News), NETS FTSE/JSE Top 40 Index Fund (South Africa) ETF (JNB: Quote, Profile, Advanced Chart, News), NETS FTSE Singapore Straits Times Index Fund ETF (SGT: Quote, Profile, Advanced Chart, News).

The Deutsche Boerse is the home of 22 new Dow Jones ETFs that have just been licensed to Commerzbank AG. The GlobeNewswire press release has identified the indexes as: Dow Jones EURO STOXX 50, Dow Jones EURO STOXX Select Dividend 30, Dow Jones STOXX 600, all 18 Dow Jones STOXX 600 Supersector indexes and the Dow Jones Industrial Average. With the access to this extensive list of indexes through ETFs, investors will have broad exposure to U.S. and European markets, as well as various sectors. Werner Buerki, chairman, STOXX supervisory board confirms that point by saying, “The 21 Dow Jones STOXX indexes chosen by Commerzbank for their lineup of ETFs offer investors broad varieties to participate in the performance of the core European markets and sectors.”

The broad market indexes are described further in the article. For example, Dow Jones EURO STOXX 50 Index is comprised of 50 sector leaders within twelve European countries, such as France, Germany or Spain.

The other main type of index is the Dow Jones STOXX 600 Supersector Index. There are 18 of this indexes that are based on companies of the Dow Jones STOXX 600 but are specific to various sectors such as Financials, Health Care, or Technology.
