As the exchange traded fund universe expands, the industry has shifted its focus to specialized and geared products. Nevertheless, equity ETFs remain the go-to investment products, accounting for the majority of the overall fund space.

According to Bianco Research, over 97% of equity ETF assets cover plain vanilla, long-only U.S. or international equity indexing strategies for the year ended June 2012, writes James Bianco at The Big Picture. While a lot of attention has been placed on inverse/leveraged products, the ETF category makes up less than 3% of overall industry assets. [Investors Moved Back to Stock ETFs in July]

Even with the increased interest in bonds, fixed-income assets only accounted for 19% of all assets, overshadowed by equity ETFs, which made up 69% of all assets.

It is also interesting to note that assets in real estate ETFs were five times larger than assets in currency funds.

According to the ETF Industry Association, fixed-income ETFs attracted $63.5 billion for the year ended June, followed by U.S. equity ETFs with $48.3 billion, global/international equities with $16.2 billion, real estate with $5.0 billion, $4.8 billion and specialized ETFs with $128 million.

The relatively new specialty category includes new “enhanced” indices that follow specific strategy when selecting component stocks.

Looking at equity ETFs, long-only U.S. equity funds brought in $45.0 billion over the year ended June, follwed by global/international with $15.3 billion, U.S. short leveraged with $1.9 billion, U.S. short with $725 million, U.S. long leveraged with $669 million, global/international long leveraged with $618 million, global/international short leveraged $202 million and global/international short $156 million.

Asset class allocations include U.S. equity funds $564 billion, global/international equities $246.5 billion, fixed income $222.1 billion, commodities $109.4 billion, real estate $28.8 billion, currencies $5.7 billion and specialty products $598 million.

Within equity ETFs, long U.S. equities accounted for $546.2 billion of the overall $564 billion, long global/international equities were $244.4 billion, U.S. long leveraged was $8.6 billion, U.S. short leveraged was $5.9 billion, U.S. short was $3.3 billion, global/international long leveraged was $824 million, global/international short leveraged was $731 million and global/international short was $503 million.
