(Story corrected to add launch of four additional single-country, small-cap ETFs, for a total launch of six funds.)

iShares, the world’s largest issuer of exchange-traded funds, launched six additional ETFs on the BATS exchange, including two focused on Finland and Denmark. The rollouts come days after the launch of a Norway-focused fund, which was the first-ever primary ETF listing on BATS.

Both of the new funds come with a 0.53 expense ratio. Links to their prospectuses and their tickers are as follows:

• iShares MSCI Denmark Capped Investable Market Index Fund (BATS: EDEN)
• iShares MSCI Finland Capped Investable Market Index Fund (BATS: EFNL)

The other four are small-cap single-country equities funds, and each comes with an annual expense ratio of 0.59 percent.

Those funds are:

• iShares MSCI Australia Small Cap Index Fund (BATS: EWAS)
• iShares MSCI Canada Small Cap Index Fund (BATS: EWCS)
• iShares MSCI Germany Small Cap Index Fund (BATS: EWGS)
• iShares MSCI United Kingdom Small Cap Index Fund (BATS: EWUS)

BATS arrival in the world of primary listings of ETFs should make for greater competition in the space, which is has been occupied solely by the New York Stock Exchange and the Nasdaq. It could mean cheaper listing fees for sponsors, though it’s not yet clear if ETF companies would ever pass on such savings to fund holders.

Earlier this week, on Jan. 24 iShares launched the iShares MSCI Norway Capped Investable Market Index Fund (BATS: ENOR).
