NEW YORK -- One of the hottest investment markets is getting ready to add even more sizzle, as new and unique exchange-traded funds (ETFs), some currently in SEC registration and still under regulatory scrutiny, are expected to roll out shortly.

That was the buzz at an ETF summit media conference held here last week, sponsored by Barclay's Global Investors of San Francisco. Barclay's is the leader of the ETF pack as the sponsor of 97 ETFs branded under the iShares name with more than $100 billion in ETF assets globally. In fact, Barclay's has the biggest market share of the exchange-traded fund market (48.8%), followed by State Street Global Advisors of Boston (33.3%) and Bank of New York (15%).
